Histological Findings in Testes of Baboons (Papio spp.) and Dwarf Bucks (Capra hircus) Subject to Repeated Immunisation Against GnRH

Veterinary Medicine and Science, Volume 12, Issue 6, November 2026.
Long‐term repeated immunisation against GnRH resulted in the absence of active spermatogenesis and may lead to irreversible infertility in dwarf bucks and baboons. Histological examination revealed a marked reduction of the seminiferous tubular lumen, complete depletion of germ cells, germ cell vacuolization and tubular hyalinization.

Microbial and Metabolic Correlates of Endometrial Dysfunction in Polycystic Ovary Syndrome: A Translational Study

BJOG: An International Journal of Obstetrics &Gynaecology, Volume 133, Issue 12, Page 2092-2102, November 2026.
ABSTRACT Objective Women with polycystic ovary syndrome (PCOS) exhibit a substantially increased risk of miscarriage, yet the underlying mechanisms remain inadequately understood. This study aimed to investigate whether specific gut microbial dysbiosis and metabolic disturbance are associated with and may potentially contribute to endometrial ...

Tanner stages of thelarche in relation to anthropometric and ultrasound predictors in premenarcheal girls

Acta Obstetricia et Gynecologica Scandinavica, Volume 105, Issue 11, Page 2221-2235, November 2026.
We found a close correlation between thelarche and internal genital maturation on pelvic ultrasound, paralleling Tanner breast stages and supporting the concept of correlated external and internal pubertal development. Abstract Introduction Thelarche is often the first sign of puberty initiation in girls.

ManyBabies 3: A Multi‐Lab Study of Infant Algebraic Rule Learning

Developmental Science, Volume 29, Issue 6, November 2026.
ABSTRACT The ability to learn and apply rules lies at the heart of cognition. In a seminal study, Marcus et al. (1999) reported that 7‐month‐old infants learned abstract rules over syllable sequences and were able to generalize those rules to novel syllable sequences.

Arcuate kisspeptin neurons display two types of calcium events: Regulation by sex, gonads, and senktide

Journal of Neuroendocrinology, Volume 38, Issue 11, November 2026.
Abstract The pattern of gonadotropin‐releasing hormone (GnRH) release controls reproduction in vertebrates and is regulated by feedback from the gonads. Evidence is accumulating that steroid‐sensitive hypothalamic arcuate kisspeptin–neurokinin B–dynorphin (KNDy) neurons drive GnRH pulses.

Recent advances in polyendocrine metabolic ovarian syndrome, formerly polycystic ovary syndrome, with emphasis on endocrine and metabolic dysfunction and cardiovascular risk

Journal of Internal Medicine, Volume 300, Issue 5, Page 590-609, November 2026.
Abstract Polyendocrine metabolic ovarian syndrome (PMOS), previously known as polycystic ovary syndrome, affects 10%–13% of women of reproductive age and remains underdiagnosed despite its substantial health burden. The introduction of the new PMOS nomenclature in 2026 reflects a fundamental shift in understanding the condition as a lifelong endocrine ...

NR4A1‐Driven Granulosa Cell Ferroptosis Contributes to Obesity‐Related Ovarian Dysfunction and Metformin‐Mediated Ovarian Protection

The FASEB Journal, Volume 40, Issue 19, 15 October 2026.
Schematic illustrating that NR4A1‐driven granulosa cell ferroptosis mediates obesity‐related ovarian dysfunction, while metformin‐mediated ovarian protection is achieved via suppression of the PI3K/AKT–NR4A1 ferroptotic signaling cascade. ABSTRACT Obesity triggers ovarian dysfunction and female infertility accompanied by granulosa cell damage ...
