Safety of gender affirming treatment in assigned female at birth transgender people and association of androgen and estrogen ß receptor polymorphisms with clinical outcomes.

PURPOSE: Gender affirming hormone treatment (GAHT) with androgens in assigned female at birth (AFAB) people with Gender Incongruence (GI) can induce and maintain variable phenotypical changes, but individual response may be genetically determined. To clarify the role of AR and ERß polymorphisms we prospectively evaluated AFAB subjects undergoing virilizing GAHT. METHODS: Fifty-two AFAB people with confirmed GI were evaluated before (T0) and after 6 (T6) and 12 months (T12) of testosterone enanthate 250 mg i.m. every 28 days. Hormone profile (testosterone, estradiol), biochemical (blood count, glyco-metabolic profile) and clinical parameters (Ferriman-Gallwey score, pelvic organs) were evaluated at each time-point, as well as number of CAG and CA repeats for AR and ERß, respectively. RESULTS: All subjects have successfully achieved testosterone levels within normal male ranges and improved their degree of virilization, in absence of significant side effects. Hemoglobin, hematocrit and red blood cells were significantly increased after treatment, but within normal ranges. Ultrasound monitoring of pelvic organs showed their significant reduction already after 6 months of GATH, in absence of remarkable abnormalities. Furthermore, a lower number of CAG repeats was associated with a higher Ferriman-Gallwey score post treatment and a higher number of CA repeats was associated with uterine volume reduction. CONCLUSION: We confirmed safety and efficacy of testosterone treatment on all measured parameters. This preliminary data hints a future role of genetic polymorphisms to tailor GAHT in GI people, but evaluation on a larger cohort is necessary as the reduced sample size could limit data generalization at this stage.

Ovarian Reserve Reduction With Surgery Is Not Correlated With the Amount of Ovarian Tissue Inadvertently Excised at Laparoscopic Surgery for Endometriomas.

The aim of the present study was to evaluate the effect of laparoscopic cystectomy on ovarian reserve by means of anti-Müllerian hormone (AMH) serial measurements and to compare AMH values with the number of inadvertently removed follicles in histological specimens. Fifty-two women were enrolled: 34 patients with endometriomas (group 1) and 18 patients with other benign ovarian cysts (group 2). All patients underwent laparoscopic cystectomy performed by a single experienced surgeon. The AMH was measured before, and 1, 3, and 6 months after cystectomy in group 1, and before and 6 months after surgery in group 2. Preoperative AMH levels (mean [standard deviation, SD]) in group 1 (3.39 [2.43] ng/mL) were not significantly different from group 2 (3.74 [2.57] ng/mL; P = .68). In group 1, a significant decrease in AMH levels of 43.4% was observed at 1 month (1.93 [1.36]; P = .003), and of 63.1% at 3 months (1.25 [1.00]; P = .007) postoperatively. The AMH increased not significantly between the third and sixth months in group 1 (+9.4%). Six months after surgery, AMH was reduced by 59.3% compared to baseline values in group 1 (P = .012), and by 29.5% in group 2 (P = .200). A significant difference in the AMH decrease was present between bilateral and monolateral endometriomas (P = .006). There was no correlation between the reduction rate of AMH and the number of follicles inadvertently removed in patients with endometriomas (P = .669). In conclusion, AMH decreases significantly after surgical excision of ovarian endometriomas. The postoperative decrease does not appear to correlate with the amount of ovarian tissue inadvertently excised with the endometrioma wall.

Inhibin B: are modified ranges needed for orchiectomised testicular cancer patients?

Inhibin B is a gonadal hormone that downregulates the pituitary production of follicle-stimulating hormone (FSH). In recent years, inhibin B has proved to be an excellent marker of spermatogenesis and even a predictive factor for the recovery of fertility in patients undergoing orchiectomy and antineoplastic treatments. We propose to study inhibin B levels in orchiectomised testicular cancer patients, in order to identify a minimum value representative of normal semen quality. This retrospective study evaluates hormonal and semen parameters of 290 normozoospermic patients attending the Laboratory of Seminology - Sperm Bank "Loredana Gandini" (Rome, Italy) for cryopreservation of seminal fluid following a diagnosis of testicular cancer (TC group) and 117 healthy, normozoospermic men as a control group (CTR group). The percentile distribution of gonadotropin and inhibin B values in the TC and CTR groups was analyzed. There was a statistically significant difference between the two groups in the levels of all hormones (P ≤ 0.001) and in all semen parameters (P < 0.05). About 20% of TC patients revealed inhibin B levels below the 5th percentile of CTR group, despite normozoospermia, and 31.4% had normal spermatogenesis in the presence of FSH values >95th percentile of CTR group. Orchiectomised patients for testicular cancer presented inhibin B levels lower than healthy patients, despite normozoospermia. Our study revealed the poor sensitivity of the current inhibin B reference range when applied to monorchidic patients, suggesting the need to establish more representative ranges to enable more appropriate counseling in relation to the patient's new endocrine condition.
