Luteinizing hormone receptor knockout mouse: What has it taught us?
Andrology, EarlyView.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 ...

Comparative Single‐Cell Transcriptomic Atlas Reveals the Genetic Regulation of Reproductive Traits
Advanced Science, Volume 13, Issue 17, 23 March 2026.A cross‐species single‐cell transcriptomic atlas of reproductive and central nervous system tissues from sheep and humans reveals conserved cellular programs and regulatory networks that regulated fertility. Integration with GWAS for sheep lifetime average litter size identifies UNC5–SLIT–BMP signaling as a core pathway coordinating neuroendocrine ...

Inhibin A and B secretion in mouse preantral follicle culture [PDF]
Human Reproduction, 1998 Conditioned media from single mouse ovarian follicles cultured from the early preantral stage up to complete maturity were analysed for different immunoreactive inhibin forms. The inhibin assays measured (i) alpha-specific inhibin, as represented by a mix of 32 and and 57 kDa inhibins, inhibin precursors, alpha-subunit and its precursors; (ii) dimeric ...

Zinc Deficiency Disrupts Germ Cell Nest Breakdown During In Vitro Ovary Culture
Molecular Reproduction and Development, Volume 93, Issue 2, February 2026.ABSTRACT In mammals, the size of the non‐renewable primordial follicle pool is established before or soon after birth. Primordial follicles, each composed of a single oocyte surrounded by somatic cells, are the only source of gametes during the entire reproductive lifespan of the female.

Isolation and characterization of preantral follicles from foetal bovine ovaries [PDF]
Veterinary Quarterly, 1994 A simple, mechanical method is described for the isolation of preantral follicles from bovine foetuses of 220-280 days of gestation. On average, 2918 + 621 (s.d.) preantral follicles were isolated per ovary. The isolated preantral follicles were characterized on the basis of the morphological appearance of the surrounding granulosa cells, the number of
