BACKGROUND
In functional hypothalamic amenorrhea (FHA), luteinizing hormone and follicle-stimulating hormone levels show high interindividual variability, which significantly limits their diagnostic value in differentiating FHA from polycystic ovary syndrome (PCOS). Our aim was to profile the LH:FSH ratio in a large sample of patients with well-defined FHA.
METHODS
This observational study included all consecutive patients with FHA presenting to the Department of Gynecologic Endocrinology and Reproductive Medicine, Medical University of Vienna, between January 2017 and August 2023. The main parameters of interest were the LH level, the FSH level, and the LH:FSH ratio. In a subgroup analysis, we compared the LH:FSH ratio of patients with PCO morphology (PCOM) on ultrasound with that of patients without PCOM.
RESULTS
A total of 135 patients were included. Only a minority of patients revealed FSH and LH levels ≤ 2.0 mIU/mL (13% and 39%, respectively). Most patients (81.5%) had an LH:FSH ratio ≤ 1.0, while a minority (2.2%) had a ratio ≥ 2.1. The LH:FSH ratio was similar in patients with and without PCOM.
CONCLUSION
In a well-defined FHA sample, the LH:FSH ratio was ≤ 1 in most patients. The LH:FSH ratio may prove useful in distinguishing FHA from PCOS but needs further investigation.

BACKGROUND
Dienogest (DNG) improves endometriosis-associated pain (EAP) and patients' quality of life; however, the modern cornerstone of the management of endometriosis is the long-term adherence of the patient to medical treatment.
OBJECTIVE
To evaluate DNG as a long-term treatment of endometriosis, focusing on patients' compliance and side effects, also correlating with different phenotypes of endometriosis.
METHODS
This was a cohort study on a group of patients with endometriosis ( = 114) undergoing long-term treatment with DNG. During the follow up visits (12, 24, and 36 months) patients were interviewed: an assessment of EAP was performed by using a visual analogue scale (VAS) and side effects were evaluated by using a specific questionnaire of 15 items.
RESULTS
At 12 months, 81% were continuing the DNG treatment, with a significant reduction of dysmenorrhea, dyspareunia, dyschezia, dysuria and chronic pelvic pain. Of the 19% that discontinued the treatment: 62% was due to spotting, reduced sexual drive, vaginal dryness, and mood disorders. The improvement of EAP was significant for all endometriosis phenotypes, especially in patients with the deep infiltrating type. At 36 months, 73% of patients were continuing the treatment, showing a significant reduction of EAP through the follow up, along with an increase of amenorrhea (from 77% at 12 months to 93% at 36 months). In a subgroup of 18 patients with gastrointestinal disorders, DNG was administered vaginally at the same dosage, showing similar results in terms of efficacy and tolerability.
CONCLUSIONS
DNG was an effective long-term treatment for all endometriosis phenotypes, with few side effects that caused the discontinuation of the treatment mainly during the first year. Thus, the course of 1-year treatment is a predictive indicator for long-term treatment adherence.

SUMMARY
Total testosterone, which is peripherally converted to its biologically active form dihydrotestosterone (DHT), is the first-line hormone investigation in hyperandrogenic states and infertility in premenopausal women. Polycystic ovary syndrome (PCOS), the most common cause of hyperandrogenism and infertility in young women, is often associated with mild elevations of total testosterone. Whereas very high levels of total testosterone (>2-3 SD of normal reference), are most often associated with hyperandrogenic signs, menstrual irregularity, rapid onset of virilization, and demand a prompt investigation. Herein, we report a case of a 32-year-old woman who was referred to the endocrinology outpatient clinic due to secondary amenorrhea and extremely high testosterone levels without any virilization signs. We initially suspected pitfalls in the testosterone laboratory test. Total serum testosterone decreased after a diethyl-ether extraction procedure was done prior to the immunoassay, but testosterone levels were still elevated. An ovarian steroid-cell tumor (SCT) was then revealed, which was thereby resected. Twenty-four hours post surgery, the total testosterone level returned to normal, and a month later menstruation resumed. This case emphasizes that any discrepancy between laboratory tests and the clinical scenario deserves a rigorous evaluation to minimize misinterpretation and errors in diagnosis and therapeutic approach. Additionally, we describe a possible mechanism of disease: a selective peripheral target-tissue response to high testosterone levels that did not cause virilization but did suppress ovulation and menstruation.
LEARNING POINTS
Total testosterone is the most clinically relevant hormone in investigating hyperandrogenic states and infertility in premenopausal women. Very high total testosterone levels in women (>2-3 SD of normal reference) are most often associated with hyperandrogenic signs, menstrual irregularities, and a rapid onset of virilization. In women with very elevated testosterone levels and the absence of clinical manifestations, laboratory interference should be suspected, and diethyl ether extraction is a useful technique when other methods fail to detect it. Ovarian steroid cell tumors (SCT) encompass a rare subgroup of sex cord-stromal tumors and usually secrete androgen hormones. SCTs are clinically malignant in 25-43% of cases. A selective response of peripheral target tissues to testosterone levels, with clinical manifestations in some tissues and no expression in others, may reflect differences in the conformation of tumor-produced testosterone molecules.

Sertoli-Leydig cell tumors (SLCT) are a rare form of sex cord stromal tumors. germline mutations have been identified in a portion of these cases. We report a 15-year-old individual who presented to a well-child visit with secondary amenorrhea and subjective observations of a deepening voice and broadening shoulders. Elevations were noted in serum testosterone, inhibin B, androstenedione, and DHEA. Pelvic ultrasound and magnetic resonance imaging (MRI) revealed a left ovarian complex lesion measuring 5.8 x 5.5 x 4.6 cm. A laparoscopic unilateral salpingo-oophorectomy was performed with negative pelvic washings and a diagnosis of stage 1A, poorly differentiated/grade 3 SLCT of the ovary. Somatic and germline testing both demonstrated pathologic variations. Adjuvant chemotherapy with cisplatin/etoposide/ifosfamide (PEI) was completed under the care of pediatric oncology, and this patient is now undergoing surveillance with no signs of recurrence. Syndrome is associated with multiple tumors, including SLCT, pleuropulmonary blastoma (PPB), cystic sarcomas, and Wilms tumor among others. Patients with SLCT found to have a mutation should undergo genetic testing and cancer screening, which may help to identify neoplasms associated with the mutation at an early stage. This case will serve as a useful addition to the literature and review suggested pre-operative, operative, and surveillance guidelines.

BACKGROUND
Epithelioid trophoblastic tumor (ETT) is the rarest gestational trophoblastic tumor, with poor response to chemotherapy. Hysterectomy, as the cornerstone therapy for early ETT, is particularly challenging in reproductive-age women who often have a strong desire for fertility preservation. The management of extra-uterine ETT could be even more complicated and inconsistent. Here we reported a case of isolated ETT lesions in lungs managed with thoracic surgery without hysterectomy.
CASE PRESENTATION
A 32-year-old woman presented with amenorrhea for 2 months. Her serum β- human chorionic gonadotropin (hCG) levels fluctuated between 52 and 75 mIU/mL. The patient underwent removal of intrauterine device and suction and curettage, but only proliferative endometrium was found. Methotrexate was given for a provisional diagnosis of ectopic pregnancy of unknown location, while β-hCG had no significant decline. She complained of mild chest pain during the past half year, and the chest computed tomography (CT) result showed two mixed ground-glass nodules of 24 mm × 14.2 mm in right upper lobe and 10 mm × 8 mm in the right lower lobe and a thin-walled cavity in the posterior segment of the left lower lobe. Right upper wedge resection and right lower segmentectomy were performed 3 months later. The result of the pathological examination of pulmonary mass indicated an epithelioid trophoblastic tumor. She was diagnosed with ETT at stage III (with right lung metastasis) according to FIGO 2000. Her menstrual cycle recovered within 1 month after the first thoracic surgery. However, β-hCG was elevated again to 9 mIU/mL, and the positron emission tomography/computed tomography (PET/CT) scans revealed the consolidation of the nodule in the left lower lobe which enlarged to about 1.0 cm × 1.7 cm. Her second pulmonary surgery without hysterectomy was conducted. Followed for 12 months for postoperative monitoring, the patient was found to be disease-free with negative results of serial serum β-hCG and chest CT.
CONCLUSION
Our case highlights the efficacy of fertility-sparing surgery for isolated ETT in lungs. The surgical management of pulmonary isolated ETT could be individualized under long-term supervision. Sporadic reports on the favorable outcome of extra-uterine ETT with fertility-sparing surgery were described in the last decades. The safety of this surgical strategy might be warranted only if enough reliable data is accumulated.

Cesarean scar ectopic pregnancy is one of the rarest of all ectopic pregnancies. Cesarean scar ectopic can occur after previous uterine manipulation, in vitro fertilization, hysterotomy, etc. With the increasing number of cesarean sections, the incidence of cesarean scar ectopics has increased worldwide. A high degree of suspicion over the occurrence of ectopic pregnancy after a cesarean section should be maintained by all healthcare workers. Timely diagnosis and treatment according to the presentation of an individual is of utmost importance. Here, we present a case of a 24-year-old second gravida with nine weeks of amenorrhea and a previous cesarean section presenting with the possibility of a scar ectopic, initially managed with medical management, followed by a planned laparotomy.

MicroRNAs (miRNAs) are single-stranded, non-coding RNAs that regulate mRNA expression on a post-transcriptional level. Observational studies suggest an association of serum miRNAs and polycystic ovary syndrome (PCOS), a common heterogeneous endocrinopathy characterized by hyperandrogenism (HA), oligo- or amenorrhea (OM) and polycystic ovaries. It is not known whether these miRNA profiles also differ between PCOS phenotypes. In this pilot study, we compared serum expression profiles between the four PCOS phenotypes (A-D) and analyzed them both in PCOS (all phenotypes) and in phenotypes with HA by quantitative-real-time PCR (qRT-PCR). The serum expression of miR-23a-3p was upregulated in phenotype B ( = 10) and discriminated it from phenotypes A ( = 11), C ( = 11) and D ( = 11, AUC = 0.837; 95%CI, 0.706-0.968; = 0.006). The expression of miR-424-5p was downregulated in phenotype C ( = 11) and discriminated it from phenotypes A, B and D (AUC = 0.801; 95%CI, 0.591-1.000; = 0.007). MiR-93-5p expression was downregulated in women with PCOS (all phenotypes, = 42) compared to controls ( = 8; = 0.042). Phenotypes with HA (A, B, C; = 32) did not show differences in the analyzed expression pattern. Our data provide new insights into phenotype-specific miRNA alterations in the serum of women with PCOS. Understanding the differential hormonal and miRNA profiles across PCOS phenotypes is important to improve the pathophysiological understanding of PCOS heterogeneity.

Review
Hyperandrogenism is a condition in which the levels of androgen hormones in the blood are significantly increased and could be of an adrenal or ovarian origin. The adrenal androgens, normally secreted by the zona reticularis, are steroid hormones with weak androgen activity. The causes of hyperandrogenism are diverse and could be endogenous and exogenous. Androgen excess affecting different tissues and organs results in clinical features such as acne, hirsutism, virilization, and reproductive dysfunction such as oligomenorrhoea/amenorrhoea. Although androgen excess is rarely associated with adrenal tumours, it is important as it could be predictive of malignancy. A careful evaluation of the androgen pattern, also in patients with clear signs of hyperandrogenism, could be useful. Laboratory evaluation should focus on measuring total testosterone levels, followed by the estimation of other androgens such as dehydroepiandrosterone and androstenedione, and using visualisation procedures in the further management. The treatment of adrenal hyperandrogenism is eminently surgical, in consideration of the frequent malignant origin. The aim of this review is to elaborate and summarize the prevalence and clinical management of hyperandrogenism of an adrenal origin by describing the physiological mechanisms of adrenal androgen steroidogenesis, the clinical manifestations of hyperandrogenism with a special reference to hyperandrogenism in adrenal adenomas and carcinomas, and the diagnostic methods that will lead us to establishing the correct diagnosis and different treatment options to manage this condition according to the clinical presentation of the patient.

Randomized Controlled Trial
Effects of injectable contraception with depot medroxyprogesterone acetate or norethisterone enanthate on estradiol levels and menstrual, psychological and behavioral measures relevant to HIV risk: The WHICH randomized trial.
BACKGROUND
Observational data suggest lower HIV risk with norethisterone enanthate (NET-EN) than with depo-medroxyprogesterone acetate intramuscular (DMPA-IM) injectable contraceptives. If confirmed, a switch between these similar injectable methods would be programmatically feasible and could impact the trajectory of the HIV epidemic. We aimed in this paper to investigate the effects of DMPA-IM and NET-EN on estradiol levels, measures of depression and sexual activity and menstrual effects, relevant to HIV risk; and to ascertain whether these measures are associated with estradiol levels.
METHODS
This open-label trial conducted at two sites in South Africa from 5 November 2018 to 30 November 2019, randomized HIV-negative women aged 18-40 to DMPA-IM 150 mg intramuscular 12-weekly (n = 262) or NET-EN 200 mg intramuscular 8-weekly (n = 259). Data were collected on hormonal, behavioral and menstrual effects at baseline and at 25 weeks (25W).
RESULTS
At 25W, median 17β estradiol levels were substantially lower than at baseline (p<0.001) for both methods: 76.5 pmol/L (interquartile range (IQR) 54.1 to 104.2) in the DMPA-IM group (n = 222), and 69.8 pmol/L (IQR: 55.1 to 89.3) in the NET-EN group (n = 225), with no statistical difference between the two methods (p = 0.450). Compared with DMPA-IM, NET-EN users reported significantly less amenorrhoea, fewer sexual acts, fewer users reporting at least one act of unprotected sex, more condom use with steady partner, more days with urge for sexual intercourse, more days feeling partner does not love her, and more days feeling sad for no reason. We did not find a clear association between estradiol levels and sexual behavior, depression and menstrual effects. Behavioral outcomes suggest less sexual exposure with NET-EN than DMPA-IM. The strength of this evidence is high due to the randomized study design and the consistency of results across the outcomes measured.
CONCLUSIONS
Estradiol levels were reduced to postmenopausal levels by both methods. Secondary outcomes suggesting less sexual exposure with NET-EN are consistent with reported observational evidence of less HIV risk with NET-EN. A randomized trial powered for HIV acquisition is feasible and needed to answer this important question.
