Pig Seminal Plasma Extracellular Vesicles Enhance Motility During Preservation of Epididymal Spermatozoa but Impair Capacitation and IVF Parameters

Andrology, EarlyView.
ABSTRACT Background Extracellular vesicles (EVs) produced by accessory sex glands play a key role in sperm functionality, influencing motility, viability, acrosome integrity, metabolic activity, and capacitation. Most studies on the effects of EVs on spermatozoa have focused on ejaculated spermatozoa, which have already been exposed to their own native

Gonadotropin and kisspeptin gene expression, but not GnRH, are impaired in cFOS deficient mice. [PDF]

, 2015
cFOS is a pleiotropic transcription factor, which binds to the AP1 site in the promoter of target genes. In the pituitary gonadotropes, cFOS mediates induction of FSHβ and GnRH receptor genes.

Does synchronising follicular wave emergence improve outcomes in non‐superstimulated donor cattle undergoing ovum pick‐up (OPU) for in vitro embryo production?

Australian Veterinary Journal, EarlyView.
In vitro embryo production (IVEP) is now a widely commercialised assisted reproductive technology used in cattle reproduction. The use of follicle‐stimulating hormone (FSH) to superstimulate donor cattle prior to ovum pick‐up (OPU) is generally regarded as an effective strategy to improve oocyte quality, developmental competence and increase embryo ...

Enhanced at puberty 1 (EAP1) is a new transcriptional regulator of the female neuroendocrine reproductive axis [PDF]

, 2007
The initiation of mammalian puberty and the maintenance of female reproductive cycles are events controlled by hypothalamic neurons that secrete the decapeptide gonadotropin-releasing hormone (GnRH).

Potential Effects of Prepubertal Exposure to Perfluorooctane Sulfonic Acid on the First Wave of Folliculogenesis in Young CD‐1 Mice

Birth Defects Research, Volume 118, Issue 5, May 2026.
ABSTRACT Background Perfluorooctane sulfonic acid (PFOS) belongs to a group of synthetic chemicals referred to as per‐ and polyfluoroalkyl substances (PFAS) that are known to degrade slowly. Exposure to PFOS has been reported to cause birth defects and disrupt female sex hormone levels in mice.

Luteinizing hormone receptor knockout mouse: What has it taught us?

Andrology, Volume 14, Issue 4, Page 1017-1028, May 2026.
Abstract Luteinizing hormone (LH), along with its agonist choriongonadotropin (hCG) in humans, is the key hormone responsible for the tropic regulation of the gonadal function. LH and hCG act through their cognate receptor, the luteinizing hormone/choriongonadotropin receptor (LHCGR; more appropriately LHR in rodents lacking CG), located in the testis ...

Recognizing menopause in women with amenorrhea induced by cytotoxic chemotherapy for endocrine-responsive early breast cancer. [PDF]

, 2012
Cytotoxic anticancer treatment may induce amenorrhea or menopause to a variable extent. These side effects may not only impair or impede fertility but also cause sexual dysfunction, bone loss, and menopausal symptoms, with a strikingly negative effect on

Women with PCOS have a later menopausal transition and a lower prevalence of menopausal symptoms at age 46: A population‐based birth cohort study

Acta Obstetricia et Gynecologica Scandinavica, Volume 105, Issue 5, Page 836-846, May 2026.
Findings from a population‐based cohort study indicate that late peri−/postmenopausal status, as well as menopausal symptoms, were less prevalent in women with PCOS at age 46, supporting the hypothesis of prolonged ovarian function and a delayed menopausal transition with this condition.

Mutation in MSH5 Causes Primary Ovarian Insufficiency and Successful Therapeutic Intervention by In Vitro Fertilisation

Journal of Cellular and Molecular Medicine, Volume 30, Issue 9, May 2026.
ABSTRACT Primary ovarian insufficiency (POI) is a genetically heterogeneous disorder characterised by cessation of menstruation before the age of 40 years with elevated levels of follicle‐stimulating hormone. Germline variants in the MSH5 gene cause POI. In this study, we investigated a Han Chinese family with POI.
