Spermatogenesis and cycle of the seminiferous epithelium.
Spermatogenesis is a complex biological process of cellular transformation that produces male haploid germ cells from diploid spermatogonial stem cells. This process has been simplifiedExpand

Localization of androgen and estrogen receptors in adult male mouse reproductive tract.
There is considerable variation, both within and between species, in reports of nuclear steroid receptor localizations in the male reproductive tract. In this study, androgen receptor (AR) andExpand

A role for oestrogens in the male reproductive system
Oestrogen is considered to be the ‘female’ hormone, whereas testosterone is considered the ‘male’ hormone. However, both hormones are present in both sexes. Thus sexual distinctions are notExpand

  • 9 July 2003
Testosterone and estrogen are no longer considered male only and female only hormones. Both hormones are important in both sexes. It was known as early as the 1930's that developmental exposure to aExpand

Expression of Stimulated by Retinoic Acid Gene 8 (Stra8) in Spermatogenic Cells Induced by Retinoic Acid: An In Vivo Study in Vitamin A-Sufficient Postnatal Murine Testes1
Abstract Vitamin A is required for male fertility and normal spermatogenesis. Retinoic acid (RA), an active metabolite of vitamin A, is necessary for spermatogonial maturation and proper entry ofExpand

ERM is required for transcriptional control of the spermatogonial stem cell niche
Division of spermatogonial stem cells produces daughter cells that either maintain their stem cell identity or undergo differentiation to form mature sperm. The Sertoli cell, the only somatic cellExpand

Immortalized germ cells undergo meiosis in vitro.
Establishing mammalian germ-cell lines capable of differentiation in vitro would greatly facilitate the study of gametogenesis and the meiotic process that is so fundamental for reproduction and theExpand

Claudin and occludin expression and function in the seminiferous epithelium
Integral membrane proteins that contribute to function of the blood–testes barrier (BTB) in mice include claudins 3, 5 and 11 and occludin. Although claudin 11 is expressed throughout all stages ofExpand
