AI Article Synopsis

  • The study aimed to assess how low-dose GH-releasing factor (GRF) affects folliculogenesis in regularly menstruating women.
  • The trial involved seven participants who received GRF during specific cycle days while serving as their own controls.
  • Results indicated that GRF treatment improved follicular growth rates and endometrial thickness, suggesting that low-dose GRF may boost ovarian activity and promote follicle development.

Article Abstract

Objective: To evaluate the effect of low-dose GH-releasing factor (GRF) on folliculogenesis in regularly menstruating women.

Design: Prospective clinical trial where individual patients served as their own control.

Setting: Outpatient Reproductive Endocrine/Infertility Clinic of the Los Angeles County-University of Southern California Medical Center, Los Angeles, California.

Patients: Seven regularly menstruating women.

Intervention: During treatment cycles, subjects received 100 micrograms SC GRF on cycle days 2 to 11 and were observed during a control cycle.

Main Outcome Measures: Follicle number and diameter, as well as endometrial thickness were all assessed by vaginal ultrasound and blood was obtained for serum FSH, LH, E2, P, GH, insulin-like growth factor 1 (IGF-1), and insulin-like growth factor binding protein-3.

Results: During cycles treated with GRF, GH, and IGF-1 levels were normal. However, follicular growth rates and E2 to FSH ratios were significantly higher. The day of the peak E2 to follicular diameter ratio after GRF was earlier than in control cycles. Endometrial growth rates were also greater with GRF.

Conclusions: Our data, although preliminary, support the hypothesis that low doses of GRF may independently stimulate the ovary and enhance folliculogenesis.

Background: Clinical diagnosis of heavy menstrual bleeding (HMB) is dependent on patient report of menstrual product usage of pads and tampons, but it is unknown if newer reusable menstrual products (cup and underwear) are similarly diagnostic.

Methods: We enrolled 20 regularly menstruating individuals with HMB for two menstrual cycles. Participants completed a retrospective baseline Pictorial Blood loss Assessment Chart (PBAC) at the time of enrolment (eligibility PBAC score ≥100) as well as several different measures with each study cycle.

Background: Menarche, a milestone in a woman's reproductive journey, is influenced by various factors such as lifestyle and dietary habits. Recent studies have corroborated this claim and prompted further investigation. This study explores the connection between menarche timing with lifestyle and dietary habits among three generations of women from the Sakaldiha block of Chandauli district and presents valuable insights into the role of diet and lifestyle in this crucial reproductive event.

Article Synopsis
  • Abdominal wall endometriosis is a rare condition, particularly occurring in the muscles of the abdominal wall, as seen in a patient with a history of cesarean sections who experienced intense menstrual pain without visible lesions.
  • Imaging studies showed no abnormalities, leading to a surgical excision of a flat lesion in the abdominal wall muscles, which confirmed the diagnosis of endometriosis after histological analysis.
  • The patient had a smooth recovery and reported complete symptom relief six months post-surgery, highlighting the need for awareness of this uncommon condition for effective diagnosis and treatment.

Oestradiol and progesterone levels are higher in menstruating women than men of the same age, and their receptors are present in their neurosensory retina and retinal pigment epithelium. However, the impact of this hormonal environment on retinal physiology in women remains unclear. Using self-reported menstrual cycle phases as a surrogate for fluctuating hormonal levels, we investigated associations with retinovascular indices on colour fundus photograph and retinal thickness in optical coherence tomography across regularly menstruating women in the UK Biobank.

Introduction: PCOS is one of the most commonly occurring endocrinopathies among women and increasingly affects adolescent populations. The connection between PCOS and various endocrinological, psychological, and CVD is increasingly recognized. Some studies have shown elevated levels of visfatin and VEGF among patients with PCOS, which are markers of vascular endothelial dysfunction.
