Background: The study was conducted to evaluate the effects of low-dose estrogen compared to placebo on ovarian activity during the traditional 7-day hormone-free interval (HFI) of an oral contraceptive (OC).
Study Design: Women were randomized to placebo or low-dose estrogen for 7 days during the HFI. Serum levels of estradiol, follicle-stimulating hormone (FSH), luteinizing hormone and inhibin B were obtained before, during and after treatment.
Results: Mean hormone levels remained constant or only increased slightly for the low-dose estrogen group compared to greater more sustained increases observed for the placebo group. Estradiol, FSH and inhibin B levels were substantially higher for those on placebo. Differences were most noticeable by the end of the HFI and persisted into the subsequent cycle.
Conclusion: Subjects receiving low-dose estrogen for 7 days during the HFI demonstrated more pronounced ovarian suppression compared to placebo as evidenced by attenuation of increases in serum inhibin B, FSH and estradiol levels.

UPDATE ON MEDICAL TREATMENT OF ENDOMETRIOSIS: NEW DRUGS OR NEW THERAPEUTIC APPROACHES?
Gynecol Obstet Invest
December 2024
Background: No conceptually new drugs for the safe and successful cure of endometriosis are likely to become available soon. Hormonal modulation of ovarian function and suppression of menstruation remain the pillars of disease control. However, existing drugs may be used following novel modalities to limit the consequences of endometriosis progression.

Menopausal symptoms of sleep disturbances, cognitive deficits, and hot flashes are understudied, in part due to the lack of animal models in which they co-occur. Common marmosets (Callithrix jacchus) are valuable nonhuman primates for studying these symptoms, and we examined changes in cognition (reversal learning), sleep (48 h/wk of sleep recorded by telemetry), and thermoregulation (nose temperature in response to mild external warming) in middle-aged, surgically-induced menopausal marmosets studied at baseline, during 3-week phases of ethinyl estradiol (EE, 4 μg/kg/day, p.o.

Background: Kallmann syndrome (KS) is a rare genetic disorder marked by hypogonadotropic hypogonadism and either anosmia or hyposmia. It exhibits genetic heterogeneity, with mutations identified in only 30 % of cases, involving various genes such as KAL1, FGFR1, FGF8, CHD7, and SOX10. Here, we present a case of gonadotropin deficiency associated with KS, observed in both a mother and her daughter, the latter conceived through assisted reproductive technology using the mother's ovum.

Essential for hormonal male contraception (HMC) is the inhibition of follicle-stimulating hormone (FSH), the hormone responsible for spermatogenesis. No drugs exist that can selectively suppress FSH without also inhibiting luteinizing hormone (LH), the hormone responsible for the biosynthesis of testosterone (T) and estradiol (E2) in men. The consequences are a loss of T and E2, with the accompanying symptoms and signs of T deficiency and E2 deficiency, respectively.

A 46-year-old woman on low-dose estrogen-progestin (LEP) therapy for endometriosis developed a right-sided pneumothorax. Surgical findings included a pulmonary bulla in the right middle lung lobe and a small hole in the center tendon of the diaphragm, both of which were partially resected. Histopathology confirmed the presence of endometrial tissue, leading to a diagnosis of thoracic endometriosis.
