Granulosa cells expressing anti-Müllerian hormone (AMH) are widely used as a marker of growing follicles. However, the in vivo roles of granulosa cells in follicular development and female fertility remain unclear. Here, we analyzed AMH-toxin receptor-mediated cell knockout (AMH-TRECK) transgenic (Tg) mice on a NOG background, in which AMH-expressing granulosa cells are specifically depleted by diphtheria toxin (DT). We first found that, after a single DT injection into postnatal AMH-TRECK Tg females, AMH-expressing granulosa cells in primary and secondary follicles exhibited cleaved caspase-3 signals 1 day later and were depleted 4 days later. Second, after repeated DT injections weekly from 1 to 7 weeks of age in AMH-TRECK Tg females, antral follicles and corpora lutea were rarely observed, and the numbers of primordial, primary, and secondary follicles were decreased. Following PMSG and hCG stimulation, repeated DT-injected Tg females exhibited a reduced number of ovulated oocytes with a low proportion of mature oocytes, resulting in reduced IVF rates and fertility. Further, after a cessation of repeated DT treatment, ovarian weight and follicular development recovered: the numbers of primary, secondary, and antral follicles were recovered, whereas the primordial follicle pool remains reduced. We conclude that selective depletion of AMH-expressing granulosa cells in vivo impairs follicular development and fertility.

During this process, ATP demands and the physiological environment of germ cells change progressively. Therefore, ATP supply strategies are shaped by adaptation to stage-specific physiological constraints rather than by selection of pathways with the highest energetic efficiency. In the testes, metabolic pathways are remodelled in a stage-dependent manner in response to requirements for stemness and genome stability, changes in substrate availability associated with passage across the blood-testis barrier, energetic demands of meiosis, and extensive cellular reorganisation during spermiogenesis. Although sperm have limited transcriptional and translational capacities in the epididymis, their membrane properties, signalling systems, and metabolic functions mature through exposure to region-specific luminal environments and molecular transfer from the epididymal epithelium. In mature sperm, glycolysis and oxidative phosphorylation are spatially compartmentalised yet functionally coordinated, with their relative contributions adjusted in response to substrate availability, oxygen tension, and functional demand. Additional processes, including carbon recycling potentially mediated by gluconeogenesis-like reactions, may support ATP homeostasis under specific conditions. This review re-evaluates these findings within a unified framework in which physiological constraints define the metabolic pathways available at each developmental stage, thereby reshaping ATP supply strategies. Metabolic remodelling in the testes, maturation in the epididymis, and integration in mature sperm thus represent successive and interconnected processes that establish adaptive ATP supply throughout male germ cell development.</p>","PeriodicalId":21127,"journal":{"name":"Reproduction","volume":" ","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this review, we synthesize current evidence linking circadian and sleep disruption to pregnancy complications, with a particular focus on the temporal regulation of key hormones, including progesterone, oestrogen, cortisol, oxytocin, and melatonin. We discuss how altered rhythmicity of hormone production and tissue responsiveness may impair target tissue function, maternal cardiovascular adaptation, and the development of gestational diabetes.
