RESUMO

RESEARCH QUESTION: How should the fertility of a woman with persistent specific ovarian dysfunction after long-term mitotane exposure be managed? DESIGN: Case report. A 33-year-old woman who underwent surgery for adrenocortical carcinoma and treated with mitotane was referred for infertility. She rapidly became amenorrhoeic while taking mitotane, a condition that persisted for 5 years after cessation. Repeated serum hormone evaluation showed collapsed androgen levels, low oestradiol, high gonadotrophins (LH 69 and 63; FSH 23 and 43 IU/l), relatively high inhibin B level and slightly decreased anti-Müllerian hormone levels (1.4 and 0.7 ng/ml). An ultrasound scan revealed an antral follicle count of 13, contrasting with high serum gonadotrophin levels. After failure to obtain follicular growth after ovarian stimulation, in-vitro maturation (IVM) of immature oocytes aspirated from the antral follicles was carried out for microinjection with the spermatozoa of the patient's partner. RESULTS: Two cycles of unstimulated egg retrieval were carried out, producing seven IVM oocytes, which were microinjected. A total of three cleavage-stage embryos were vitrified and unsuccessfully transferred after endometrial preparation using hormone replacement therapy (HRT). After a 20-month break, two new attempts were carried out under HRT with the aim of achieving a fresh embryo transfer. The last attempt succeeded after transfer of a single day-2 embryo, and the patient delivered a healthy baby. CONCLUSION: Persistent specific impaired ovarian function 5 years after withdrawal of mitotane, and the first live birth after IVM in this situation, are reported. The question of fertility preservation before long-term mitotane treatment is raised.

RESUMO

RESEARCH QUESTION: To compare stimulated cycle (STC) versus modified natural cycle (MNC) for endometrial preparation prior to frozen embryo transfer (FET) in terms of convenience and efficacy. DESIGN: Prospective, open-label, randomized controlled study including 119 patients aged 20-38 years, undergoing intra-conjugal IVF/intracytoplasmic sperm injection, having regular cycles, at least two day 2 or day 3 frozen embryos, for whom it was the first or second FET performed, randomized to either MNC (n = 59) or STC (n = 60). Monitoring consisted of ultrasound and hormonal measurements. The number of monitoring visits required was compared between the two groups. RESULTS: STC required a significantly lower number of monitoring visits compared with MNC (3.6 ± 0.9 versus 4.4 ± 1.1, respectively, P < 0.0001), a lower number of blood tests (2.7 ± 0.8 versus 3.5 ± 1.0, respectively, P < 0.0001) and of ultrasounds (1.2 ± 0.4 versus 1.5 ± 0.6, respectively, P = 0.0039). FET during 'non-opening' hours (22.6% versus 27.5%, respectively, P = 0.32) and cancellation rates (11.7% versus 11.9%, respectively, P = 0.97) were comparable between the STC and MNC groups. No difference concerning HCG-positive rates (34.0% versus 23.1%, respectively, P = 0.22) nor live birth rates (24.5% for STC versus 23.1% for MNC, respectively, P = 0.86) was observed. Quality of life as defined by the FertiQol score was not different (P > 0.05 for each item). CONCLUSION: Altogether, these findings can be used for everyday clinical practice to better inform patients when deciding on the protocol to use for FET. These results suggest that MNC is a good option for patients reluctant to have injections, but requires increased monitoring. STC may offer more flexibility for patients and IVF centres.

RESUMO

BACKGROUND: Testicular morphology and immunohistochemical studies have never been reported in genetically documented adult patients with 5 alpha-reductase type 2 deficiency (5α-R2 deficiency). CASE PRESENTATION: We describe the testicular histopathology of a 17-year-old XY subject with 5α-R2 deficiency caused by the recurrent homozygous Gly115Asp loss of function mutation of the SRD5A2 gene.We also performed an immunohistochemical analysis in order to further study the relationship between seminiferous tubules structure, Sertoli cell differentiation and androgenic signaling impairment in this case. We thus evaluated the testicular expression of the anti-Müllerian hormone (AMH), androgen receptor (AR) and 3ß-hydroxysteroid dehydrogenase (3ßHSD). Histological analysis revealed a heterogeneous aspect with a majority (92%) of seminiferous tubules (ST) presenting a mature aspect but containing only Sertoli cells and devoid of germ cells and spermatogenesis. Focal areas of immature ST (8%) were also found. Testicular AR and 3ßHSD expression were detected in adult male control, 5α-R2 deficiency and CAIS subjects. However, AMH expression was heterogeneous (detectable only in few AR negative prepubertal ST, but otherwise repressed) in the 5α-R2 deficiency, conversely to normal adult testis in which AMH was uniformly repressed and to an adult CAIS testis in which AMH was uniformly and strongly expressed. CONCLUSION: Intratesticular testosterone can repress AMH by itself, independently of its metabolism into dihydrotestosterone. We also compare our results to the few post pubertal cases of 5α-R2 deficiency with available histological testicular description, reported in the literature. We will discuss these histological findings, in the more general context of evaluating the fertility potential of these patients if they were raised as males and were azoospermic.

RESUMO

OBJECTIVE: To describe the use, efficacy and safety profile of follitropin delta in women undergoing IVF/ICSI in routine clinical practice after one treatment cycle. STUDY DESIGN: This was a French multicenter, prospective, observational study conducted in 14 fertility centers between June 2020 and June 2021. During this period, 248 women undergoing IVF or ICSI were treated with follitropin delta for the first time. Women were followed up to 10-11 weeks after the first fresh or frozen embryo transfer. The main outcomes were use of dosing algorithm, follitropin delta dosing patterns, ovarian response, pregnancy, and adverse drug reactions in routine clinical practice. RESULTS: The analyzable population consisted of 223 patients with mean ± SD age of 33.0 ± 4.4 years, body weight of 65.7 ± 11.8 kg, and the median (IQR) AMH level was 2.6 (1.5-4.0) ng/mL. For 193 patients (86.5 %) it was the first IVF/ICSI cycle and for 30 (13.5 %) the second. The algorithm was used for the calculation of the starting dose for 88.3 % of the patients. The mean daily starting dose of follitropin delta was 11.4 ± 4.1mcg for the whole analyzable population and 14.4 ± 5.2 mcg for the sub-group of 26 patients dosed without the algorithm. The mean duration of stimulation with follitropin delta was 10.8 ± 5.2 days. The mean total dose of follitropin delta administered was 122.2 ± 80.0 mcg. An antagonist protocol was used in 90.3 % of patients. The mean ± SD number of oocytes retrieved among patients that started stimulation was 11.3 ± 6.8 and 46.1 % of patients achieved the targeted response of the algorithm of 8-14 oocytes retrieved. A fresh transfer was performed for 77.6 % of patients; the mean ± SD number of embryos transferred was 1.3 ± 0.5. The implantation rate was 36.0 %. Per started cycle, clinical pregnancy was reported in 35.0 % of the patients and ongoing pregnancy in 29.6 %. In total, 5 patients (2.2 %) reported an event of OHSS. CONCLUSION: Clinical results as collected in routine clinical practice are promising, showing a favorable effectiveness-safety profile of follitropin delta for a very varied patient population (including anovulatory PCOS, very poor responders, or non-IVF naïve patients). These real-world data complement results from clinical trials and provide useful information for usual clinical practice within a heterogeneous population group.

RESUMO

CONTEXT: Isolated hypogonadotropic hypogonadism (IHH), characterized by gonadotropin deficiency and absent puberty, is very rare in women. IHH prevents pubertal ovarian stimulation, but anti-Müllerian hormone (AMH) and antral follicle count (AFC) have not been studied. OBJECTIVES: (1) To compare, in IHH vs controls, AMH, ovarian volume (OV), and AFC. (2) To compare, in IHH, ovarian responses to recombinant human follicle-stimulating hormone (rhFSH) and rhFSH plus recombinant human luteinizing hormone (rhLH). SUBJECTS: Sixty-eight IHH women; 51 matched healthy women. METHODS: Serum LH, FSH, sex steroids, inhibin B (InhB), AMH, and OV and AFC (sonography) were compared. Ovarian response during rhFSH administration was assessed in 12 IHH women with low AMH levels and low AFC and compared with hormonal changes observed in six additional IHH women receiving rhFSH plus rhLH. RESULTS: InhB was lower in IHH than in controls. AMH levels were also significantly lower in the patients, but two-thirds had normal values. Mean OV and total, larger, and smaller AFCs were lower in IHH than in controls. Ovarian stimulation by rhFSH led to a significant increase in serum estradiol and InhB levels and in the number of larger antral follicles. AMH and smaller AFC increased early during rhFSH stimulation but then declined despite continued stimulation. rhFSH plus rhLH stimulation led to a significantly higher increase in estradiol levels but to similar changes in circulating InhB and AMH than with rhFSH alone. CONCLUSIONS: IHH women have both low AMH levels and low AFC. However, their decrease can be reversed by follicle-stimulating hormone. Serum AMH and AFC should not serve as prognostic markers of fertility in this population.

RESUMO

Kallmann syndrome (KS) patients carrying FGFR1 mutations can transmit the disorder to their offspring as can asymptomatic female carriers of mutations in KAL1. We describe for the first time two cases in which KS was suspected during fetal life because of the family context and malformation detection by fetal ultrasound: syndactyly or unilateral renal agenesis in subjects with respectively FGFR1 and KAL1 mutations. In relevant family history, ultrasound monitoring can detect KS associated signs before birth and thus enable neonatal diagnosis and early management. These observations also underline the importance of genetic counselling for patients who may transmit KS to their offspring.

RESUMO

CONTEXT: Primary ovarian insufficiency (POI) is a major cause of anovulation and infertility in women. This disease affects 1% of women before 40 years, and several genetic causes have been reported. OBJECTIVE: The aim of the study was to evaluate the prevalence of NOBOX mutations in a new large cohort of women with POI and to characterize these variants and identify a NOBOX novel target gene. PATIENTS AND METHODS: A total of 213 unrelated patients with POI were screened for NOBOX mutations, and luciferase reporter assays were performed for the mutations identified. RESULTS: We reported 3 novel and 2 recurrent heterozygous missense NOBOX rare variants found in 12 patients but not in 724 alleles from ethnic-matched individual women with occurrence of menopause at a normal age. Their functional impact had been tested on the classic growth differentiation factor-9 (GDF9) promoter and on KIT-L, a new NOBOX target gene. The p.Gly91Thr, p.Gly111Arg, p.Arg117Trp, p.Lys371Thr, and p.Pro619Leu mutations were deleterious for protein function. CONCLUSIONS: In our series, 5.6% of the patients with POI displayed heterozygous NOBOX mutations. We demonstrate that KIT-L could be now a direct NOBOX target. These findings replicate the high prevalence of the association between the NOBOX rare variants and POI.

RESUMO

CONTEXT: Mitotane is an adrenolytic and anticortisolic drug used in adrenocortical carcinoma (ACC), Cushing's disease (CD), and ectopic ACTH syndrome. Its effects on the ovaries are unknown. OBJECTIVE: To evaluate the ovarian and gonadotrope effects of mitotane therapy in premenopausal women. PATIENTS: We studied 21 premenopausal women (ACC: n=13; CD: n=8; median age 33 years, range 18-45 years) receiving mitotane at a median initial dose of 3 g/day (range 1.5-6 g/day). METHODS: Gynecological history was collected and ovarian ultrasound was performed. Four women also underwent ovarian CT or magnetic resonance imaging. Serum gonadotropin, estradiol (E2), androgens, sex hormone-binding globulin (SHBG), and circulating mitotane levels were determined at diagnosis and during mitotane therapy. RESULTS: In the women included, ovarian macrocysts (bilateral in 51%) were detected after a median 11 months (range: 3-36) of mitotane exposure. The median number of macrocysts per woman was two (range: 1-4) and the median diameter of the largest cysts was 50 mm (range: 26-90). Menstrual irregularities and/or pelvic pain were present in 15 out of 21 women at macrocyst diagnosis. In two women, the macrocysts were revealed by complications (ovarian torsion and hemorrhagic macrocyst rupture) that required surgery. Mitotane therapy was associated with a significant decrease in androstenedione and testosterone levels and a significant increase in LH levels. Serum FSH and E2 levels were also increased, and SHBG levels rose markedly. CONCLUSIONS: Mitotane therapy causes significant morphological and ovarian/gonadotrope hormonal abnormalities in premenopausal women. Follicular thecal steroid synthesis appears to be specifically altered and the subsequent increase in gonadotropins might explain the development of macrocysts. The mechanisms underlying these adverse effects, whose exact prevalence in this population still needs to be determined, are discussed.

RESUMO

In order to compare the effectiveness of urinary and recombinant FSH (rFSH) preparations in achieving the threshold of follicular growth, stimulated cycles from patients with chronic anovulation, treated with a constant dose of FSH until the emergence of a selected follicle, were retrospectively analysed. Sixty-four cycles were performed using a similar starting dose of either urinary FSH (group 1) or rFSH (group 2), which was kept constant up to the time of follicular selection, assessed on ultrasound (follicular diameter >10 mm). The results of this study showed that, while the number of selected follicles was similar, the mean daily FSH dose required to achieve the threshold of follicular selection was significantly lower in group 2 (70.4 +/- 3.4 IU/day) than in group 1 (86.5 +/- 4 IU/day; P < 0.005). Furthermore, at the time of human chorionic gonadotrophin (HCG) administration, the total FSH dose was significantly lower in group 2 than in group 1, but plasma oestradiol values were equivalent. These data suggest that the higher effectiveness of rFSH preparations over urinary ones may be explained by a lower threshold dose required to achieve follicular selection.

RESUMO

CONTEXT: Insulin-like factor 3 (INSL3) is a testicular hormone secreted during fetal life, the neonatal period, and after puberty. OBJECTIVE: To measure INSL3 levels in a large series of men with congenital hypogonadotropic hypogonadism (CHH)/ Kallmann syndrome (KS), in order to assess its diagnostic value and to investigate its regulation. PATIENTS: We studied 281 CHH/KS patients (91 untreated, 96 receiving T, and 94 receiving combined gonadotropin therapy [human chorionic gonadotropin, hCG, and FSH]) and 72 age-matched healthy men. METHODS: Serum INSL3 was immunoassayed with a validated RIA. RESULTS: Mean (±SD) INSL3 levels (pg/mL) were 659 ± 279 in controls and lower (60 ± 43; P < .001) in untreated CHH/KS patients, with no overlap between the two groups, when the threshold of 250 pg/mL was used. Basal INSL3 levels were lower in both untreated CHH/KS men with cryptorchidism than in those with intrascrotal testes and in patients with testicular volumes below 4 mL. Significant positive correlations between INSL3 and both serum total T and LH levels were observed in untreated CHH/KS. Mean INSL3 levels remained low in T-treated CHH/KS patients and were significantly higher in men receiving combined hCG-FSH therapy (P < .001), but the increase was lower cryptorchid patients. FSH-hCG combination therapy or hCG monotherapy, contrary to T and FSH monotherapies, significantly increased INSL3 levels in CHH/KS. CONCLUSIONS: INSL3 is as sensitive a marker as T for the evaluation of altered Leydig cell function in CHH/KS patients. INSL3 levels correlate with LH levels in CHH/KS men showing, together with the rise in INSL3 levels during hCG therapy, that INSL3 secretion seems not constitutively secreted during adulthood but is dependence on pituitary LH.

RESUMO

OBJECTIVE: To evaluate the degree of E2 deficiency in male congenital hypogonadotropic hypogonadism (CHH), and its response to different hormonal treatments. DESIGN: Retrospective and prospective studies. SETTING: Academic institution. PATIENT(S): Untreated or treated CHH, healthy men, untreated men with Klinefelter syndrome (KS). INTERVENTION(S): Serum sex hormone-binding globulin (SHBG) and total E2 (TE2) as well as bioavailable (BE2) and free (FE2) levels were measured and determined. MAIN OUTCOME MEASURE(S): Total, bioavailable, and free testosterone, TE2, BE2, FE2 were compared in normal men, untreated and treated CHH and in untreated KS. RESULT(S): TE2, BE2, and FE2 levels were very significantly lower in untreated patients with CHH (n=91) than in controls (n=63) and in patients with KS (n=45). The TE2 correlated positively with serum total T in patients with CHH. The TE2 also correlated very positively with serum LH in the combined population of patients with CHH and healthy men, suggesting that low E2 levels in CHH are due to severe LH-driven T deficiency. All fractions of circulating E2 were very significantly higher in patients with CHH receiving T enanthate (n=101) or the FSH-hCG combination (n=88) than in untreated patients with CHH. Contrary to dihydrotestosterone (DHT), both T enanthate and combined FSH-hCG therapy significantly and prospectively increased TE2 levels in patients with CHH. CONCLUSION(S): Contrary to KS, the male hypogonadism observed in CHH is associated with profound E2 deficiency, which can be overcome by aromatizable androgen or combined gonadotropin therapy.

RESUMO

OBJECTIVE: To describe a patient with primary amenorrhea revealing an occult progesterone-secreting ovarian tumor. DESIGN: Case report. SETTING: University medical center. PATIENT(S): A 20-year-old woman with primary amenorrhea. INTERVENTION(S): Investigations to identify the source of progesterone secretion. MAIN OUTCOME MEASURE(S): Discovery of an occult progesterone-secreting ovarian tumor. RESULT(S): Initial ovarian ultrasonography did not show any abnormal mass. Catheterization of ovarian veins suggested a right ovarian source of progesterone. After long-term follow-up, a right ovarian tumor became apparent and was surgically removed. After surgery, progesterone levels decreased and normal ovulatory cycles resumed. Pathologic and immunohistochemical analysis showed a Leydig cell tumor expressing cytochrome P450 side-chain cleavage and 3ss-hydroxysteroïd dehydrogenase enzymes, which are involved in progesterone biosynthesis, whereas P45017alpha-hydroxylase was not expressed, explaining the absence of hyperandrogenemia. Before surgery, two LH pulses were detected during a 6-hour study period and a lack of ovarian response to pulsatile GnRH administration. CONCLUSION: This is the first case of isolated progesterone secretion by an occult ovarian Leydig cell tumor and a novel etiology of primary amenorrhea. The results also suggest that sustained progesterone can exert an inhibitory effect on gonadotropin secretion at both hypothalamic and pituitary levels.
