Background/objectives: Minipuberty is thought to play an important role in the sexual maturation of infants. Maternal disorders during pregnancy were found to have an impact on the activity of the reproductive axis in the first year of life. This prospective, matched, cohort study was aimed at investigating whether the course of minipuberty in boys is affected by maternal gestational diabetes mellitus (GDM).

The aim of this study is to evaluate the distribution of the histological results of the endocervical curettage (ECC) at large loop excision of the transformation zone (LLETZ) as well as the additional diagnostic information and its impact on further clinical treatment recommendations in accordance with national guidelines. The ECC in addition to LLETZ can serve to detect (pre)cancerogenic lesions above the endocervical cone margin, although its predictive value as well as diagnostic accuracy remains vague due to limited studies performed on this topic. In this retrospective cohort study, 1121 patients who underwent LLETZ and concomitant ECC during a twelve-year period (2009-2021) were analyzed.

Background: To date, there is no reliable measure for the prevention of postoperative hemorrhage after thyroid surgery. An increase in the postoperative hemorrhage rate at our institution in 2021 prompted us to look for possible causes with a special focus on perioperative systolic blood pressure, the individual surgeon, and surgeon-to-patient gender congruence.

Methods: We drew on our prospectively managed database to review 43,360 consecutive thyroid surgeries.

Minipuberty is the second phase of physiological activation of the reproductive axis, playing a role in the postnatal development of sexual organs. The course of female minipuberty was found to be affected by low maternal vitamin D status and hypothyroidism during pregnancy. The aim of the current study was to assess the hormonal profile and the size of sexual organs in daughters of mothers with gestational diabetes mellitus.

Purpose: Polycystic ovary syndrome (PCOS) is the leading cause of anovulatory infertility, often requiring ovarian stimulation in affected women attempting to conceive. Male partner semen quality and shared lifestyle factors can significantly impact reproductive outcomes. However, current international guidelines lack evidence-based recommendations on the necessity and timing of semen analysis for the fertility management of anovulatory PCOS women.

Article Synopsis
  • Minipuberty refers to the temporary activation of the reproductive hormone system, essential for developing genital organs in males and females.
  • A study found that daughters of women with low vitamin D during pregnancy had increased hormone activity and larger reproductive organs compared to those born to women with sufficient vitamin D levels.
  • The research indicates that maternal vitamin D deficiency leads to longer-lasting and more pronounced reproductive system activation in female infants, suggesting the impact of maternal health on offspring development.

: Fallopian tubal pathology is a primary risk factor for female infertility, with simple proximal disease and proximal disease extending more distally being more common than pure distal occlusion. Proximal tubal occlusion is often attributed to ascending events, such as pelvic inflammatory disease. Conversely, while distal occlusion can also be attributable to ascending pelvic inflammatory disease, it can also have a pelvic origin, such as through endometriosis and ruptured appendicitis.

Hysteroscopy has been recognized as a reliable method for the evaluation of female infertility for several years. The outpatient setting is particularly convenient, as patients do not require general anesthesia and do not have to stay overnight. In recent years, more and more articles have dealt with the role of diagnostic hysteroscopy in tubal evaluation.

Article Synopsis
  • In a study of women referred for potential PCOS, it was found that at least 2% were misdiagnosed and actually had Functional Hypothalamic Amenorrhea (FHA).
  • There is a need for better diagnostic markers to distinguish between PCOS and FHA to prevent misdiagnosis.
  • Incorrect treatment for undiagnosed FHA could lead to harmful long-term effects for women.

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.

Purpose: Functional hypothalamic amenorrhea (FHA) is due to hypothalamic dysregulation. Literature lacks data about prolactin in FHA women, although both prolactin levels and FHA are associated with stress. Moreover, polycystic ovarian morphology is common in FHA and there is an association between FHA and polycystic ovary syndrome.

Background: Women with functional hypothalamic amenorrhea (FHA) reveal polycystic ovarian morphology (PCOM) in up to 50%. If stress sensitivity in women with polycystic ovary syndrome (PCOS) is the reason why PCOS women are prone to develop FHA, patients with FHA caused by stress should reveal PCOM more often.

Methods: In a retrospective cohort study, 38 stress-associated and 38 excessive exercise-induced FHA women were included.

Postoperative intraabdominal adhesions can occur after more than 90% of gynecologic surgeries. They not only cause chronic pelvic pain and small bowel obstruction, but are also one of the main reasons for infertility. Adhesions are not only a burden for the affected patients, but are also a burden for the healthcare system, since the treatment of adhesion-associated complications costs a considerable amount of money.

There are limited data on how non-infectious risk factors influence tubal patency in women with subfertility. With hormonal shifts influencing tubal secretions, it has been argued that subfertile women with polycystic ovary syndrome (PCOS) have lower tubal patency. In a retrospective study, 216 women, who underwent diagnostic evaluation for PCOS and infertility, were included.
