Is there a role for ovarian stimulation and intra-uterine insemination after age 40?

The objective of this study was to determine the conception rate in infertile couples in which the female partner was > or = 40 years old and who had received ovarian stimulation treatment and intra-uterine insemination (IUI). It was a retrospective study of 77 patients who underwent a total of 210 treatment cycles. Protocols for ovulation induction included clomiphene citrate, human menopausal gonadotrophin (HMG) and clomiphene citrate plus HMG. Patients were monitored using transvaginal ultrasound, and two IUI were performed 24 and 48 h after the determination of urinary luteinizing hormone (LH) surge or human chorionic gonadotrophin (HCG) injection. A total of 11 pregnancies were reported, giving a pregnancy rate of 14% per patient and 5% per cycle. Eight spontaneous abortions occurred, giving a pregnancy wastage of 73%. In a previous comparative analysis of 543 patients < 39 years old receiving IUI and identical protocols of ovarian stimulation, 141 pregnancies were achieved, giving a pregnancy rate of 21% per patient and 10% per cycle. The miscarriage rate in that group was 18%. This report compares IUI results for women > or = 40 years with those obtained previously for younger women, and shows the very poor success rate in women > 40 years of age. This information will be important in the proper counselling of this group of patients, as well as indicating that a prompt recommendation for assisted reproductive treatment should be made soon after the failure of a few attempted cycles of ovarian stimulation treatment and IUI.

Directional coronary atherectomy in women compared with men.

The influence of gender on the procedural outcome of directional coronary atherectomy (DCA) is controversial. This study of 373 consecutive patients (418 lesions) undergoing DCA demonstrates that the procedural success rate of DCA is significantly lower in women compared with men (72.7 vs. 82.9%, p = 0.011). Women have significantly smaller coronary arteries than men (2.5 mm vs. 2.7 mm, p = 0.028) and were older than men (66 vs. 61 years, p = 0.0001). Multivariate analysis identifies small coronary vessel size rather than female gender per se as an independent predictor of poor procedural outcome. Procedural success rates in women with coronary vessel size > or = 2.5 mm is significantly higher (92.2%) than in women with coronary vessel size < 2.5 mm (73.1%), and parallels that in men with vessel size > or = 2.5 mm (89.3%). Inability to engage the ostium of the coronary artery adequately with the guiding catheter and to cross the lesion with the atherectomy device is significantly more common in women compared with men. Major ischemic complication rates are similar in women and men (8.5 vs. 8.7%). Groin complications are significantly more common in women compared with men (13.5 vs. 2.9%). We conclude that procedural success rates in women may be improved by careful patient selection, with particular attention to small vessel size. DCA is best performed in vessels > 2.5 mm in diameter.

Predictors of Pregnancy Success in Repeated Miscarriage

Factors that may have a bearing on subsequent pregnancy success or failure in patients with recurrent abortion were examined in 165 women with a history of three or more consecutive miscarriages in the first trimester. The overall success rate was 67.9%. Factors that were found to correlate significantly with success rate were length of abortion history, total number of abortions, interval from last miscarriage to present pregnancy, and whether there was any degree of subfertility. Logistic regression analysis showed that the abortion x years index and maternal age accounted for all the variation observed in our data. Where all other known causes of abortions are excluded, recurrent aborters can be subdivided into two populations--namely, those with a relatively good prognosis characterized by a short abortion history and absence of subfertility problems, compared to those with a poor prognosis namely those with a long abortion history or presence of subfertility problems. These data clearly demonstrate major differences in success rates in women depending on the number of abortions and the length of abortion history (abortion x year index), particularly in women over the age of 30 years.

Construction of a neovagina for patients with a flat perineum

Vaginal dilatation affords an acceptable functional success rate for women with vaginal agenesis, provided there is an introitus with a pouch or dimple. In contrast, women with a flat perineum who lack labia majora, labia minora, and vaginal introitus have no alternative to development of a vagina-like orifice other than surgical vaginoplasty. This study addresses the anatomic and functional success rate of these women after undergoing modified McIndoe technique. Thirty-four patients with microphallus were assigned the female gender as the sex of rearing at the Johns Hopkins Hospital between 1951 and 1987. A majority of patients underwent surgical revision of the external genitalia and gonadectomy before 2 years of age. Family counseling was begun at birth. Of these patients, 15 (17 to 25 years old) who requested the ability to have sexual relations underwent modified McIndoe vaginoplasty. All 15 of these women have experienced satisfactory coitus. All but one patient have an adequate size vagina. Results of this group indicate that patients with ambiguous genitalia as a result of male hermaphroditism or microphallus can achieve functional success after vaginal creation with a modified McIndoe technique despite the presence of a flat perineum.
