Many studies have showed the role of androgens on ovarian follicular maturation. The present study investigated the effect of serum concentration of androgens, LH, and insulin-like growth factor 1 (IGF1) in the early follicular phase on the results of the ovulation induction (I/O) and intrauterine insemination (IUI) cycles. This cross-sectional study was done in the infertility clinic of Akbar Abadi hospital. Fifty-nine infertile patients who were not affected by polycystic ovary syndrome (PCO) and were candidates for induction ovulation or intrauterine insemination were chosen at random. The serum concentrations of androgens (free testosterone, dihydroepiandrosterone, and androstenedione), LH, and IGF1 were measured on the third day of menstruation. Sonographic monitoring was started from the ninth day of the cycle. The ampule of hCG was injected when there was at least one follicle with the diameter of 18 mm. The relationships of concentration of androgens, LH, and IGF1 with follicular growth parameters and pregnancy rate were analysed. There was no statistically significant link between the number and diameter of follicles with concentration of free testosterone, dihydroepiandrosterone, androstenedione, IGF1, and LH. There was no statistically significant link between the number of follicles in the ovaries and concentrations of testosterone (P = 0.090 and r = 0.223), dihydroepiandrosterone (P = 0.642 and r = 0.062), androstenedione (P = 0.526 and r = 0.084), IGF1 (P = 0.470 and r = 0.096), and LH (P = 0.446 and r = 0.102). There was no statistically significant link between the mean follicular diameter and concentration of testosterone (P = 0.822 and r = 0.03), dihydroepiandrosterone (P = 0.733 and r = 0.045), androstenedione (P = 0.526 and r = 0.084), IGF1 (P = 0.799 and r = 0.034), and LH (P = 0.626 and r = 0.065). Beta human chorionic gonadotropin (β-hCG) was positive in 11 patients (18.6%) and negative in 48 patients (81.4%). Serum concentrations of androgen profile, LH, and IGF1 in the positive (β-hCG) group were not significantly different in comparison with the negative β-hCG group. It seems that in women who were not affected by PCO, concentrations of free testosterone, dihydroepiandrosterone, androstenedione, IGF1, and LH in the early follicular phase were not related to follicular growth parameters and pregnancy rate.

Abstract Background: It is controversial whether gonadotropin-releasing hormone agonist (GnRHa) pretreatment can benefit the pregnancy outcomes in frozen-thawed embryo transfer (FET) cycles. In most of studies, GnRHa was administered during the mid-luteal phase for pretreatment. Few studies focus on FET cycles with GnRHa administered in early follicle phase.Methods: The retrospective cohort study was conducted in a university-affiliated IVF center. 630 patients in the GnRHa FET group and 1141 patients in the hormone replacement treatment (HRT) FET without GnRHa group from October 2017 to March 2019 were included. The menstruation cycle of these patients was irregular. Results: There were no differences observed between the two groups in patient’s characteristics. However, the GnRHa FET group showed a higher percentage of endometrium with triple line pattern (94.8% vs 89.6%, p<0.001) on the day of progesterone administration, and an increased implantation rate (34.7% vs 30%, p<0.01), biochemical pregnancy rate (60.6% vs 54.3%, p = 0.009), and clinical pregnancy rate (49.8% vs 43.3%, p = 0.008), as compared to that in the HRT FET cycles with similar endometrial thickness, ectopic pregnancy rate, and early miscarriage rate. Binary logistic regression analysis showed the GnRHa FET group to be associated with an increased chance of clinical pregnancy rate compared with HRT FET without GnRHa group (P=0.014, odds ratio [OR] 1.30, 95% confidence interval [CI] 1.06-1.61).Conclusions: Pretreatment with a long-acting GnRHa in early follicular phase can improve the clinical outcome of the FET cycles. However, further randomized control trials (RCTs) will be needed to verify these results.

The aims of this study were to investigate the role of inhibin in the distribution of healthy and atretic antral follicles and the secretion patterns of gonadotrophins. Ewes were actively immunized against either alphaN or alphaC of the inhibin alpha subunit with a primary injection and three booster injections. The control ewes received adjuvant only. The ovaries were removed either before or at 24 h after hCG administration in a synchronized follicular phase 48 h after removal of intravaginal progesterone pessaries. Morphological observations were made on every fifth section of the complete ovary (one per ewe) stained with haematoxylin and eosin. The mean number of corpora lutea observed per ewe with corpora lutea was not significantly different in ewes immunized against alphaN (2.4; alphaN-immunized ewes) or alphaC (2.6; alphaC-immunized ewes), and control (2.4) ewes, although some corpora lutea appeared cystic in the immunized ovaries. Compared with luteal phase concentrations, mean basal FSH concentrations in the early follicular phase were significantly increased in the alphaC-immunized ewes, similar in alphaN-immunized ewes and reduced in control ewes. No differences were observed in any of the LH parameters. Before hCG treatment, healthy antral follicles > 1 mm in diameter were not observed in any of the 52 follicles in the aC-immunized ewes and were observed in one of 37 follicles from alphaN-immunized ewes compared with 19 of 28 follicles in control ewes (P < 0.0001). For healthy antral follicles < 1 mm in diameter, there were 72 of 85 follicles in the alphaC-immunized ewes, 79 of 81 follicles in the alphaN-immunized ewes and 81 of 82 follicles in the control ewes. Similar results were obtained in healthy antral follicles < 1 mm in diameter at 24 h after hCG administration. In contrast to the control ewes, no healthy preovulatory follicles (> 6 mm in diameter) were observed in alphaN- and alphaC-immunized ewes either before or 24 h after hCG administration. Two newly formed corpora lutea from alphaC-immunized ovaries contained retained oocytes compared with none in control and alphaN-immunized ovaries. In conclusion, immunization against alphaN and alphaC may result in disruption of the normal processes of antral follicular growth and maturation independent of the concentrations of FSH and LH.

Increased reproductive success is among the most commonly proposed adaptive functions of romantic love. Here, we tested if hormonal changes associated with falling in love may co-vary with hormonal profiles that predict increased fecundity in women. We compared blood serum levels of estradiol (E2, E2/T), luteinizing hormone (LH), follicle-stimulating hormone (FSH), prolactin (PRL), free testosterone (fT), and cortisol (CT), measured in the early follicular phase of the menstrual cycle in single women (N = 69) and in women at the beginning of a romantic heterosexual relationship who reported being in love with their partner (N = 47). Participants were healthy, regularly cycling women aged 24 to 33 who did not use hormonal contraception. We found that women in love had higher levels of gonadotropins (FSH, LH) and lower testosterone levels compared to single women who were not in love. These groups of women did not, however, differ in terms of estradiol, prolactin, or cortisol levels.

Abstract The pattern of inhibin concentrations in blood during the menstrual cycle in primates has suggested an endocrine role of inhibin in the negative feedback control of FSH secretion during the luteal phase. Conversely, the fall in inhibin during the late luteal phase may play a role in the rise in serum FSH during the luteal-follicular phase transition. This hypothesis was examined by determining the effects of manipulation of inhibin on FSH secretion in stumptailed macaques. During the mid-luteal phase the putative inhibin feedback was inhibited by i.v. administration of 20 ml of ovine antiserum to human recombinant inhibin in 4 macaques. FSH secretion was unaffected during the initial 24 h period post-treatment and the timing of the rise in FSH which occurred during the subsequent luteal-follicular phase transition was normal. To determine whether the elevated serum concentrations of FSH observed during the early follicular phase could be reduced by administration of inhibin, 5 cyclic macaques were treated with 200 μg of recombinant human inhibin i.v. Serum FSH concentrations were unaltered. These results suggest that inhibin does not play a major role in modulating FSH secretion during the luteal-follicular phase transition.

Abstract Background Some studies have stated that intrauterine insemination (IUI) with controlled ovarian stimulation (COS) might increase the pregnancy rate, while others suggest that IUI in the natural cycle (NC) should be the first line of treatment. It remains unclear whether it is necessary to use COS at the same time when IUI is applied to treat isolated male factor infertility. Thus, we aimed to investigate efficacy of IUI with COS for isolated male factor infertility. Methods A total of 601 IUI cycles from 307 couples who sought medical care for isolated male factor infertility between January 2010 and February 2020 were divided into two groups: NC-IUI and COS-IUI. The COS-IUI group was further divided into two subgroups according to the number of pre-ovulatory follicles on the day of HCG: cycles with monofollicular development (one follicle group) and cycles with at least two pre-ovulatory follicles (≥ 2 follicles group). The IUI outcomes, including clinical pregnancy, live birth, spontaneous abortion, ectopic pregnancy, and multiple pregnancy rates were compared. Results The clinical pregnancy, live birth, spontaneous abortion, and ectopic pregnancy rates were comparable between the NC-IUI and COS-IUI group. Similar results were also observed among the NC-IUI, one follicle, and ≥ 2 follicles groups. However, with respect to the multiple pregnancy rate, a trend toward higher multiple pregnancy rate was observed in the COS-IUI group compared to the NC-IUI group (8.7% vs. 0, P = 0.091), and a significant difference was found between the NC-IUI and ≥ 2 follicles group (0 vs. 16.7%, P = 0.033). Conclusion In COS cycles, especially in those with at least two pre-ovulatory follicles, the multiple pregnancy rate increased without a substantial gain in overall pregnancy rate; thus, COS should not be preferred in IUI for isolated male factor infertility. If COS is required, one stimulated follicle and one healthy baby should be the goal considering the safety of both mothers and foetuses.
