Purpose: This descriptive analysis evaluated the 2022 assisted reproductive technology (ART) data collected by the Japan Society of Obstetrics and Gynecology registry.
Methods And Results: In 2022 (cutoff date 30 November 2023), 634 of 635 registered ART facilities participated; 602 implemented ART treatment, with 543 630 registered cycles and 77 206 neonates (9.1% and 10.
Purpose: Polycystic ovary syndrome (PCOS) significantly affects women. This study investigated the association between serum anti-Müllerian hormone (AMH) levels and menstrual cycle disorders, and AMH for PCOS in a general cohort of young Japanese women.
Methods: We measured serum AMH levels in 528 healthy female students at two universities in Japan between 2014 and 2020.

Background: Primary ovarian insufficiency (POI) is characterized by the development of hypergonadotropic hypogonadism before 40 years of age and leads to intractable infertility. Although in vitro fertilization and embryo transfer with donated eggs enables pregnancy, not a few patients desire pregnancy using their oocytes. However, follicular development is rare and unpredictable in patients with POI.

Methods: Forty-three women with endometriomas were compared to 22 women with benign ovarian cysts and 30 women who underwent assisted reproduction as controls. Changes in serum LRG levels were assessed before and after surgery, and during dienogest treatment.
Background: Evidence suggests that hypothyroidism and thyroid autoimmunity (TAI) are possibly associated with ovarian dysfunction. This meta-analysis aimed to investigate whether hypothyroidism and/or TAI affect the ovarian reserve and evaluated using the anti-Mullerian hormone (AMH).
Methods: PubMed, EMBASE, Web of Science, and Cochrane Controlled Trials Register databases from inception to October 2020 were searched to identify relevant studies.
Our case and the literature review suggest that placenta accreta spectrum, with use of uterotonics and manual removal of placenta, could be risk factors for postpartum unscarred uterine rupture.

This can be addressed using appropriate animal models of PCOS. In this review, we describe rodent models of hormone-induced PCOS that focus on the perturbation of the hypothalamic-pituitary-ovary (HPO) axis and abnormalities in neuropeptide levels.

- A study in Japan examined how adenomyosis affects pregnancy complications and outcomes by surveying 725 medical facilities.
- The research included data from 272 pregnant women with adenomyosis, identifying complications such as miscarriages, preterm deliveries, and hypertension, without significant differences based on treatment types.
- Findings suggest that larger and diffuse adenomyosis is linked to worse pregnancy outcomes, with increased risks of hypertension and infections in those with the diffuse type.
Aim: A multicenter, retrospective survey was conducted in order to investigate the current clinical status of adenomyosis in Japan.
Methods: The questionnaires covered the management of infertile women with adenomyosis and the outcomes of infertility treatment in women with adenomyosis. The questionnaires were sent to 1149 facilities in Japan.
