Abstract
ObjectiveInfertility of ovulatory cause can account for a quarter of infertility etiologies and one of the questions in the patients' clinical history is about their self-perception of the regularity of their menstrual cycles. The aim of this study was to assess whether the information on menstrual regularity is consistent with the assessment of the presence or absence of ovulation.MethodsCross-sectional study. The inclusion criteria were: patients with infertility for at least one year, complete examination and ovulation monitoring, aged between 18 and 38 years completed. The patients were divided into two paired groups: those who reported regular menstrual cycles and those who reported irregular cycles. In the ultrasonographic monitoring of ovulation we separated those who ovulated from those who did not ovulate, and applied the Fischer's test.ResultsAmong the 199 patients who reported having regular menstrual cycles, 113 had proven ovulation upon ultrasound monitoring and 86 patients did not ovulate. Among the 29 patients who reported irregular cycles, 24 did not ovulated at the cycle monitoring. The Fisher's exact test was applied and the p-value found was significant.ConclusionThe story of the patient in the clinical interview about the presence of regular or irregular menstruation correlates with the presence or absence of ovulation, it should be taken into consideration in the reasoning regarding the infertility etiology. This report would be important to guide the patient's ovulatory regularity diagnosis.
Highlights
With female puberty, women reach fertility through the beginning of the monthly reproductive cycles that prepare the body for pregnancy (Moore, 2004)
The following biochemical tests were requested for all patients: follicle-stimulating hormone (FSH) between 2nd and 4th day of the cycle, luteinizing hormone (LH), prolactin and thyroid-stimulating hormone (TSH)
The groups were subjected to statistical tests to see whether they were similar to the average of the variables desirable for the pairing
Summary
Women reach fertility through the beginning of the monthly reproductive cycles that prepare the body for pregnancy (Moore, 2004). The menstrual cycle consists of all the physiological changes caused by the integrated action of the cortex-hypothalamus-pituitary-ovarian-uterine axis, and ends and begins with menstruation. The patterns of menstrual bleeding are considered relevant indicators of reproductive health, but few studies focus on these aspects. Bleeding patterns are hypothetically associated with hormonal fluctuations during the cycle. In the medical history of couple with infertility are the usual questions about the patient’s menstrual regularity. Information is often based on the patient’s memory, sometimes caught off guard by the question. The aim of this study is to assess whether the information on menstrual regularity is consistent with the assessment of the presence or absence of ovulation and if it is important as a component of the patient’s clinical history
