Male Sexual Activity Research Articles

The decline of male sexual activity and function after surgical treatment for rectal cancer.

The prevalence of sequelae following rectal cancer (RC) treatment is high. We investigate the prevalence and temporal change in sexual dysfunction among male RC patient, along with their counselling and treatment needs and associations between sexual dysfunction and clinical factors. Patient/materials and methods: Patient-reported outcome measures were completed 3 and 12 months after RC surgery. We used the five-item International Index of Erectile Function score to measure sexual function in sexually active patients and ad hoc items to explore their sexual activity level, causes of disrupted sexual life, and self-rated sexual function. Clinical data were obtained from the Danish Colorectal Cancer Group database Results: In total, 364 of 490 (74%) eligible male patients were included. Their mean age (standard deviation [SD]) at surgery was 68.3 (11) years. Forty-one percent reported being sexually inactive at the time of diagnosis. Among sexually active men, 44% had resigned from sexual activity at 12 months, mainly due to erectile dysfunction (ED), as reported by 55%. Only 16% experienced improvement; 19% experienced a worsening of their ED category in the 12-month observation time. Stoma was associated with both ED (odds ratio [OR] 5.6; 95% confidence interval [CI] [1.8, 17.4]) and low self-rated sexual function (OR 3.5 95% CI [1.8 , 6.7]). Phone contact to discuss sexual problems was requested by 29%; 19% were referred to professional treatment. Sexual dysfunction is common following RC, without improvement over time. Systematic screening enables identification of patients needing professional help.

Use of immunocontraception in the regulation of male goat sexual activity.

This study focused on continuous monitoring of the immunocontraceptive effect of Improvac® vaccine on the sexual activity of male goats determined by measuring plasma testosterone levels, testicular biometric and ejaculate examination. The animals in the experimental group (n=12) were administered two doses of 2 ml of Improvac® at a four-week interval; the animals in the control group (n=5) received 2 ml of saline. Blood collection, semen collection and testicular measurements were performed at 14-day intervals. A total of 8 samples were collected from each animal. In 9 animals a significant decrease (p<0.05) in testosterone concentration was observed two weeks after the first dose. At the end of the experiment (16 weeks), eight goats reached a testosterone concentration below the detection limit and one goat had a concentration of 0.47nmol/L. The testicular size was significantly (p<0.01) smaller four weeks after the first dose. At the end of the experiment, the testicular size was approximately three times smaller (p<0.001). Motility was 0% in two goats at the end of the experiment, 1% in one animal and 10% in one animal. The median sperm concentration was significantly lower (p<0.01) at the end of the study. A significant (p<0.0001) shift in the percentage of morphological changes was recorded eight weeks after the first administration. At the end of the study, there were five animals with azoospermia, two with 100% morphologically altered sperm, one with 99% and one with 96% morphologically altered sperm. In the three male goats, a significant skin reaction occurred after the first application, which resulted in an inadequate response to the treatment. Our results show that Improvac had a significant effect on the sexual function and sperm production in 9 out of 12 male goats.

Personal genital satisfaction is associated with differences in perception of male and female sexual anatomy and function.

Prior studies primarily of men correlated low personal genital satisfaction (PGS) with decreased sexual activity; however, the association between PGS and genital anatomy perceptions is unknown, and there is a paucity of studies examining women. We assessed the relationship between genital satisfaction, survey respondent sexual activity, and perceptions of anatomy and function. A 54-item REDCap survey was distributed to any-gendered volunteers ≥18 years of age through ResearchMatch from January to March 2023. Responses were split into (1) high PGS and (2) low PGS. Analysis was performed using chi-square tests on survey responses and a Mann Whitney U test on median satisfaction level. Outcomes were genital anatomy perceptions, sexual activity, and respondents' PGS. Of the 649 respondents who started the survey, 560 (86.3%) completed it. Median PGS was 7 of 10, forming subgroups of high (≥7 of 10) satisfaction (n = 317 of 560 [56.6%]) and low (<7 of 10) satisfaction (n = 243 of 560 [43.4%]). The mean age was 45.8 ± 16.8 years, and demographics were notable for 72.1% women (n = 404 of 560), 83.2% White (n = 466 of 560), 47.9% married (n = 268 of 560), and 75.5% bachelor's degree holders (n = 423 of 560). Comparing high- and low-PGS groups, more low-PGS respondents felt normal flaccid penis length to be <2 inches (11.1% vs 5.1%; P = .008). High-PGS respondents more often responded that it is normal for women to have orgasms over half the time (20.8% vs 13.2%; P = .0002) or to identify as being sexually active (81.1% vs 71.6%; P = .008). Women were more likely than men to report larger normal testicle sizes as 60.1 to 90 mL (24.5% vs 10.3%; P < .0001), whereas more men felt that normal testicle size was 7 to 15 mL (26.3% vs 11.4%; P < .0001). Orgasm length perceptions also differed: more women felt female orgasm length was 2.6 to 5 seconds (36.6% vs 16.7%; P < .0001), and more men believed female orgasms to be longer, at 7.6 to 10 seconds (29.5% vs 17.3%; P = .002), 10.1 to 12.5 seconds (11.5% vs 5.2%; P = .0008), and >12.5 seconds (12.2% vs 5.7%; P = .009). Respondents' views on their genitalia differed by gender, with women more likely to feel that their genitals are normal compared with men (89.4% vs 75.0%; P < .0001). PGS may be a useful screening tool given its association with sexual activity. Our large-scale survey assesses public perceptions of genital anatomy and function. Limitations include a lack of gender nonbinary perceptions. Gender and PGS interact with perceptions of male anatomy and female sexual activity, and the frequency of sexual activity was higher among high-PGS respondents; however, the direction of these interactions remains unclear and requires future causal analysis.

The Macroscopic Measurement Of The Liver And Kidney Of Male Mice (Rattus Norvegicus Berkenhout) Treated With Neptunia Plena Lour Leaf Extract

The Supan Supan Laki plant (N. plena Lour) has been used traditionally by a group of people in Pal Batu Village, Paminggir District, North Hulu Sungai Regency as a herbal medicine to increase male sexual activity. Based on previous research, this plant has been proven to have a positive effect in increasing fertility in test animals. However, until now, there is no certainty regarding the safety of using this plant. This study aims to examine the effects and safety of consuming Supan Supan Laki extract on the macroscopic appearance of the liver and kidneys in mice. This research was carried out, there were four treatment groups in this study, namely Na-CMC 0.5%; 87.5mg/KgBW; 175mg/KgBW; and 350mg/KgBW, given for 28 days using a Completely Randomized Design (CRD) trial design. On the 29th day, surgery was performed to observe the liver and kidney macroscopically. Measurement of color, surface and relative organ weight parameters of the kidneys and liver of mice. The results of the study showed that administration of Supan Supan Laki leaf extract caused significant changes in the macroscopic appearance of the liver and kidney organs. In the research analysis using the One Way Anova test, the results of the test showed that the liver (p&gt;0.05) did not have a significant level of variation, while the kidney (p&lt;0.05) had a significant level of variation so that it could be concluded that the effect of N.plena Lour leaf extract have different effects on the relative weight of the heart and kidney organs.

(287) Influence of Severe Chronic Scrotal Pain on Men’s Sexual Activity: An Indication for Surgery?

Abstract Introduction Severe chronic scrotal pain significantly influences numerous aspects of a patient’s life and activities, particularly sexual activity. Objectives This study seeks to explore the clinical characteristics and the effects of chronic scrotal pain on male sexual activity, with a focus on patients with severe chronic scrotal pain who were candidates for microsurgical denervation of the spermatic cord. Methods This is an observational study that encompassed all patients with severe chronic scrotal pain who underwent microsurgical denervation of the spermatic cord at the Department of Andrology, Binh Dan Hospital, from January 1, 2022, to May 31, 2023, after other causes had been excluded. Results Thirty-one patients with chronic scrotal pain underwent surgery, with a mean age of 24.2 ± 4.3 years and a pain duration of 2.3 ± 1.6 years. Pain was located in the scrotum (41.3%), testis-epididymis (47.8%), spermatic cord (24.6%), and inguinal (15.1%), with postepididymitis (45.3%) being the predominant cause. The average Numerical Rating Scale (NRS) pain score before surgery was 6.8 ± 2.3. Thirteen out of thirty-one patients experienced severe pain (NRS = 7-10). The Quality of Life (QOL) scores were 6.75 ± 1.1 for patients with moderate pain and 4.6 ± 4.0 for those with severe pain. A smaller testicle size was observed in 43.5% of patients, and 51.6% had varicose veins on ultrasound, measuring 3.4 ± 1.2 mm. Sixteen out of thirty-one patients reported that scrotal pain impacted their sexual activity. Patients with higher pain scales (NRS 7-10) had significant effects on erectile function compared to those with moderate pain (P &amp;lt; 0.05). Decreased libido was reported in 34.1%, and lowered testosterone levels in 37.5% of the patient group. Sexual activity induced pain in 60.9% of cases, and the incidence of erectile dysfunction was significantly higher in the high pain scale group (P = 0.02). No significant statistical difference was observed between the duration of intercourse and the severity of scrotal pain. Conclusion Chronic scrotal pain, predominantly observed in young patients, has substantial impacts on the quality of life and sexual performance. Therefore, a meticulous consideration of sexual factors is imperative in male patients with chronic scrotal pain. Surgical indications for chronic scrotal pain treatment may be deemed necessary for sexual disorders associated with scrotal pain. Disclosure No.

(352) High Genital Satisfaction is Associated with Increased Sexual Frequency and Larger Perceived Penile Anatomy

Abstract Introduction Satisfaction with personal genitalia has profound impacts on quality of life and sexual health. Prior studies of men correlated genital dissatisfaction with decreased sexual activity; however, the association between satisfaction and perceptions of “normal” genital anatomy is unknown. Objective We aimed to assess the interplay between genital satisfaction, sexual activity, and genital anatomy expectations. Methods A 54-item RedCap survey was distributed to volunteers aged ≥18 years through the ResearchMatch database from January to March 2023. Responses were split into: 1) high genital satisfaction (≥7/10 satisfaction rating) and 2) low satisfaction (&amp;lt;7/10). We collected data on perceptions of “normal” genital anatomy and function in addition to sexual function and preferences. Analysis was performed using JMP Pro 16. Results 649 respondents initiated and 558 respondents completed the survey (86% completion rate). Median genital satisfaction was 7/10. 27.9% of respondents identified as male and 72.1% as female. The mean age was 45.8 years, 83.2% were white, 47.9% married or 25.0% never married, and 75.5% had at least a bachelor’s degree. More low-satisfaction respondents reported perceived “normal” erect penis girth &amp;lt;2 inches (7.8% vs. 3.8%, p=0.04), flaccid penis length &amp;lt;2 inches (11.1% vs. 5.1%, p&amp;lt;0.01) and semen volume &amp;lt;2 mL (5.8% vs. 1.3%, p&amp;lt;0.01). More high-satisfaction respondents believed women had orgasms over half the time (20.8% vs. 13.2%, p=0.02). More high-satisfaction respondents were sexually active (81.1% vs. 71.6%, p&amp;lt;0.01). Of the respondents who were sexually active, high satisfaction was more associated with sexual encounters 1-3 times weekly (44.5% vs. 32.1%, p&amp;lt;0.01). Conclusions Genital satisfaction impacts perceptions of male anatomy and female sexual activity. Frequency of sexual activity was higher among high-satisfaction respondents, thus genital satisfaction may be a useful screening tool to determine sexual activity. Disclosure No.

Investigation of extragonadal teratomas in two Poecilia wingei.

Teratoma is a rare tumour in fish consisting of tissues from more than one germ layer, that may be located in either the gonads or extragonadal sites. Teratomas in many fish species remain poorly understood. In this work, we performed the first histological examinations of extragonadal teratomas in Poecilia wingei and also examined the influence of a large teratoma on male sexual activity. The studied teratomas shared general organizational features, but they also had variations in both external and internal features. In teratomas, the most common and highly differentiated tissues were striated muscle and nervous tissue. Despite the tumour, the male P. wingei exhibited normal mating behaviour and retained the ability for successful copulation. The structural features of extragonadal teratomas in guppy fish indicate a possible connection between these tumours and a failure of conserved processes operating in the embryonic germline.

Effects of male to female Japanese quail (Coturnix japonica) interactions on female´s plumage and skin condition

The high incidence of aggression in mature domestic birds is a major concern for the poultry industry. In Japanese quails, an overall score on female plumage condition was proposed to identify whether their male partner showed an aggressive profile towards them. This study delves further into the relationship between aggressive and/or sexual male Japanese quail performances and the plumage and skin condition of their female counterparts. We used an original “more rigorous” scoring system and a single female body areas approach, aiming to easily identify specific regions that are predominantly affected by male´s aggressive and/or sexual behavior and could be used to predict male´s performance. Additionally, this study investigates whether deteriorations in female plumage and skin condition induced by males when paired with a single female (1 male and 1 female) for pedigree purposes can also be similarly evidenced when females are housed for multiplication purposes in groups of 4 every 1 male. After 60 days of cohabitation, males were classified as low or highly aggressive based on the number of pecks recorded, and female skin and plumage status was evaluated. The study found significant positive correlations between male pecking and female's head and neck plumage and skin status, but no correlation between male sexual behaviors and female plumage and skin status. Using the male classification according to the extreme aggressive performance towards their female mate, females housed with highly aggressive males had worse neck plumage and head and neck skin status than females housed with low aggressive males. In addition, these highly aggressive males initiated more copulation sequences but achieved the same number of cloacal contacts as low-aggressive males. Regarding groups, highly aggressive males continued to express aggressive behaviors more frequently to the 4 females than those classified as low aggressive. It was observed that the female group housed with highly aggressive males had worse head plumage status than those housed with low aggressive males. Our findings suggest that the level of male aggressiveness can be discerned by examining the condition of the females' head and neck plumage, irrespective of whether they are housed in pairs or within groups. Plumage and skin body regions and conditions evaluated appear not useful when aiming to infer male quail sexual activity.

Changes in social, sexual, and hedonic behaviors in rats in response to stress and restoration by a negative allosteric modulator of α5-subunit containing GABA receptor

Major depressive disorder (MDD) is a debilitating and costly human condition. Treatment for MDD relies heavily on the use of antidepressants that are slow to produce mood-related changes and are not effective in all patients, such as selective serotonin reuptake inhibitors (SSRIs). Several novel compounds, including negative allosteric modulators of GABA-A receptors containing the α5-subunit (GABA-NAMs), are under investigation for potential fast acting therapeutic use in MDD. Preclinical evidence that these compounds produce a rapid antidepressant-like response comes primarily from simple tests of escape behavior and preference for rewarding stimuli after chronic stress. To increase the ethological relevance of these compounds, we tested the hypothesis that the GABA-NAM, L-655,708, would produce an antidepressant-like response in more complex stress-sensitive social and sex behaviors, which are of relevance to the symptoms of human depression. In male rats subjected to chronic restraint stress, injection of L-655,708 increased reward in a sexual conditioned place preference task, increased male sexual activity with a receptive female, and re-established male social dominance hierarchies within 24 h. We also report increased sucrose preference in the social defeat stress (SDS) model of depression following GABA-NAM administration, demonstrating that its antidepressant-like actions are independent of the type of chronic stress administered. This work extends the impact of GABA-NAMs beyond traditional tests of anhedonia and further supports the development of alpha5 subunit-selective GABA-NAMs as a potential fast-acting therapeutic approach for treating human MDD.

Gender Differences in Response to COVID-19 Infection and Vaccination.

Since COVID-19 first appeared, a number of follow-up events have taken place. In an effort to find a solution to this catastrophe, a great deal of study and analysis has been conducted. Because of the high morbidity and exceptionally large losses, scientists are being pushed to conduct more research and find vaccination and treatments. The virus has a wide range of effects, one of which is how it affects sexual activity in both men and women. The impact of the cardiovascular system and susceptibility to embolism, lung stress, and infection heightens the probability of hospitalization in the intensive care unit for pregnant women who have contracted COVID-19. There is no evidence of infection being passed from mother to child. In the current review, the role of COVID-19 infection and vaccination on male and female sexual activity, hormones, and the menstrual cycle for females, as well as on male sex hormones and sexual activity during infection and after vaccination, are being investigated. There are no reports of the virus being isolated from the semen of an infected patient or recently recovered patients. A recent investigation on the influence of the virus on gender susceptibility to sexual organs and function has been uncovered throughout this study.

The endogenous cannabinoid system modulates male sexual behavior expression.

The endocannabinoid system (ECS) plays a key neuromodulatory role in the brain. Main features of endocannabinoids (eCBs) are that they are produced on demand, in response to enhanced neuronal activity, act as retrograde messengers, and participate in the induction of brain plasticity processes. Sexual activity is a motivated behavior and therefore, the mesolimbic dopaminergic system (MSL) plays a central role in the control of its appetitive component (drive to engage in copulation). In turn, copulation activates mesolimbic dopamine neurons and repeated copulation produces the continuous activation of the MSL system. Sustained sexual activity leads to the achievement of sexual satiety, which main outcome is the transient transformation of sexually active male rats into sexually inhibited animals. Thus, 24 h after copulation to satiety, the sexually satiated males exhibit a decreased sexual motivation and do not respond to the presence of a sexually receptive female with sexual activity. Interestingly, blockade of cannabinoid receptor 1 (CB1R) during the copulation to satiety process, interferes with both the appearance of the long-lasting sexual inhibition and the decrease in sexual motivation in the sexually satiated males. This effect is reproduced when blocking CB1R at the ventral tegmental area evidencing the involvement of MSL eCBs in the induction of this sexual inhibitory state. Here we review the available evidence regarding the effects of cannabinoids, including exogenously administered eCBs, on male rodent sexual behavior of both sexually competent animals and rat sub populations spontaneously showing copulatory deficits, considered useful to model some human male sexual dysfunctions. We also include the effects of cannabis preparations on human male sexual activity. Finally, we review the role played by the ECS in the control of male sexual behavior expression with the aid of the sexual satiety phenomenon. Sexual satiety appears as a suitable model for the study of the relationship between eCB signaling, MSL synaptic plasticity and the modulation of male sexual motivation under physiological conditions that might be useful for the understanding of MSL functioning, eCB-mediated plasticity and their relationship with motivational processes.

Male sexual activity with age-Brazilian specialists point of view

There is an established concept in society that men decrease their sexual activity with age and, if they are intellectual, this reduction occurs early. However, if men with the same health characteristics were studied, probably the results would be less unfavourable to the elderly. The daily normal sperm density is (50 to 250) X 106 sperm/ml of seminal fluid and extragonadal spermatozoal reserve is from (500 to 1000) X 106, of which about 200 X 106 are available for ejaculation. There are several factors that reduce spermatogenesis, including age, but the most fertile forms of spermatozoa and their motility reach their highest concentration between 40 and 50 years. The minimal sperm count effective in fertilization is 20 X 106 sperm/ml semen, a value that can be found even after the age of 80 years. Considering that semen is continuously produced, there is a natural desire for ejaculation, manifested by libido, regardless of age, ethnicity, social class and intellect, as long as there are no impeding factors. Sexual dysfunctions result from emotional and psychic disorders, serious pelvic and systemic diseases, as well as complications from trauma, surgical treatments and radiotherapy. Sexual activities are natural and, like all other physiological aspects, are influenced by organic, mental, social, cultural and educational disorders.

COMPLICATIONS AFTER PENIS ENHANCEMENT WITH HYALURONIC ACID: A LITERATURE REVIEW

Introduction. The penis is a symbol of the primal sense of male fertility and sexual activity, which affects the sense of male personality and the ability to satisfy a partner. Some patients experience discomfort, even if their penis is within the normal size range from an anatomical point of view. The reason for the spread of penis enlargement procedures is related to the feeling of masculinity that the appearance of the genitals can give a man, as well as a changed perception of his body. Penis enlargement procedures are becoming more and more common among men who seek to achieve a more desirable aesthetic of their male organ. In addition, penis enlargement methods remain a controversial issue, as they do not have clear indications and can cause complications. Materials and methods. This study reviewed the literature on complications after penile enhancement with hyaluronic acid (HA). To achieve this goal, we conducted a systematic search for scientific medical information in English-language databases such as MEDLINE, Embase, AMED (Allied and Complementary Medicine), and HMIC (Health Management Information Consortium). We analyzed all articles that met the specified search parameters. In addition, we manually searched for relevant references in the found texts. Results. The use of HA injections for penis enlargement in men shows a low rate of complications both in the early- and long-term period after the procedure. In a small percentage of patients, early and expected side effects included swelling, bruising, subcutaneous nodules, and infections. In this work, radical ways of their correction are proposed for all types of complications, which makes the use of HA safe and effective for penis enlargement. Conclusions. Nowadays, there is a lack of high-level evidence-based information on complications after HA injections. Due to the growing demand for these procedures, the issue of their safety is relevant. According to the available statistics, the overall incidence of complications after HA injections is spontaneous without further side effects. If complications are detected, the prognosis after treatment is satisfactory. As a result, there are no standardized surgical protocols and recommendations for penile enhancement with hyaluronic acid in the world.

What Affects Male Sexual Activity: A Comprehensive Review

What Affects Male Sexual Activity: A Comprehensive Review

Interactive effects of arrival date, territory quality and male polyterritorial behaviour on the mating system of the sedge warbler Acrocephalus schoenobaenus: a path analysis

Classical models predict that male fitness is based on resources monopolized and invested in reproduction, and/or on individual quality providing offspring with sexually attractive traits or viable genes. However, these factors are frequently correlated, making their relative influence on male fitness difficult to describe and quantify. We analysed the relative influence of the main features of the sedge warbler's Acrocephalus schoenobaenus breeding system, i.e. age, arrival date, territory quality, male sexual activity (song and polyterritorial behaviour), on males' mating success, fledging success and local recruitment. Results show that this species' breeding system involves three main paths: 1) earlier‐arriving males have higher mating success, regardless of territory quality, 2) the quality of territories pre‐empted by earlier males directly influences recruitment and 3) mating success is influenced by male sexual activity (polyterritorial behaviour), but an additional territory also affects recruitment directly. As arrival date plays a significant role in all the paths, the whole system seems to depend on male quality; although the benefits accruing to male fitness are obtained not only through sexual selection but also through resource monopolization.

Antidepressant-like effect of male mating behavior through oxytocin-induced CREB signaling

Male sexual activity reduces the level of depression through oxytocin (OT) release within the brain. In this study, we showed that male mating behavior reduces depression-like behavior through OT-induced cAMP response element binding protein (CREB) signaling in the hippocampus. Moreover, we showed that mating behavior in wild-type (WT) male mice increased CREB phosphorylation in hippocampus, whereas that OT receptor knockout (OTR KO) male mice had no effect on CREB phosphorylation. CREB phosphorylation in hippocampus was also increased after OT induction in hippocampal slices prepared from WT mice. In addition, male mating behavior induced the expression of brain-derived neurotrophic factor (BDNF), which was not observed in OTR KO mice. Antidepressant-like effect of mating behavior had no effect in OTR KO mice. These findings suggest that male sexual activity has antidepressant effects through OT-induced CREB signaling in the hippocampus.

Immunohistochemical detection of chlamydia trachomatis in sexually transmitted infectious proctitis

IntroductionSince 2003, a progressive increase in sexually transmitted infections (STI), presented as proctitis, has been described in homosexual men. In 2013 Arnold et al. described microscopic features that enable pathologists to formulate a histological diagnosis of STI related proctitis. The aim of this study is to identify the presence of Chlamydia trachomatis by immunohistochemistry in a group of patients with male to male sexual activity and pathology compatible with STI proctitis.MethodsCross-sectional study. The study included 54 patients with risky sexual activity and histopathology compatible with STI-proctitis according to Arnold´s recommendations. The Chlamydia trachomatis identification was carried out retrospectively on paraffin blocks using mouse monoclonal antibodies from Santa Cruz biotechnology.Resultsall patients were young men with male to male sexual activity, 69% were positive for HIV. The most common endoscopic presentation was rectal ulcer (61%). Basal lymphoplasmacytic inflammation and mild crypt distortion were the most common histological findings. The immunohistochemical study identified positivity for Chlamydia trachomatis in 40% (18 of 45 tested) of STI proctitis cases.DiscussionThe epidemiological and endoscopic characteristics of the patients studied are similar to those previously reported. In accordance with Arnold et al., the most common histological findings were (a) mild distortion of the crypts; (b) dense and basal lymphoplasmacytic infiltrate and (c) scarcity of eosinophils. The positivity of chlamydia trachomatis in immunohistochemistry was lower than others studies that used PCR for this purpose. We did not find similar published studies to compare our results.ConclusionsIn summary, 54 cases of patients with STI related proctitis are presented, all of them with distinctive histological characteristics and third of the cases tested positive by IHC for Chlamydia trachomatis.

New data on clearwing moths (Lepidoptera: Sesiidae) of Sakhalin Island

Four species of clearwing moths found in Sakhalin Island in July 2021. Pen-nisetia hylaeiformis (Laspeyres, 1801), Sesia yezoensis (Hampson, 1919) and Synanthedon bicingulata (Staudinger, 1887) were collected using synthetic sex pheromones. Females of Synanthedon herzi Špatenka et O. Gorbunov, 1992 were collected from inflorescences of Eupatorium chinense L. (Asteraceae). Synanthedon bicingulata is recorded for the fauna of the island for the first time. Pennisetia hylaeiformis is represented by the subspecies assimilis Arita, 1992. For each of the collected species, data on the distribution, larval host plants, and sexual activity of males are given.

Surgical outcome of congenital penile curvature treatment with corporal rotation technique

Congenital penile curvature (CPC) is a rare condition in men but has considerable impact on male sexual activity as well as their mental health. Many techniques had been proposed to manage this condition, however the corporal rotation technique had the advantage of preserving the penile length. Therefore, we conducted a study on 16 men with CPC who were treated with corporal rotation surgery to evaluate the outcome of this technique. The results showed that the mean degree of curvature was 51 ± 12.2 degree. The majority of patients had a moderate penile curvature (&lt; 60 degree) and ventral curvature (75%). After the surgery, the residual curvature decreased significantly (from 51 ± 12.2 degree to 16.6 ± 6.34 degree with p &lt; 0.001). We observed no remarkable changes in all penile dimensions including stretched penile length (13.6 ± 0.93cm before the surgery compared with 13.3 ± 0.89cm after the surgery with p = 0.01). Erectile function of the subjects was also significantly improved especially in the intercourse satisfaction domain.
