TL;DR: It is shown that oestrogen regulates the reabsorption of luminal fluid in the head of the epididymis, which raises further concern over the potential direct effects of environmental oestrogens on male reproduction and reported declines in human sperm counts.

TL;DR: It is concluded that germ cells are a site of estrogen synthesis in the adult mouse testis through the conversion of cytochrome P450 enzyme to estrogen.

TL;DR: Dietary genistein at 500-1500 ppm produces antilipogenic effects in mice at serum levels that humans are realistically exposed to, indicating it may be a critical aspect of its adipose effects.

TL;DR: The results indicate that all organs in the male excurrent ductal system of the rat express ERalpha and are potential targets of estrogen, however, the ductuli efferentes are the site of the most intense ERalpha expression.

TL;DR: Examination of morphological and functional changes in adult seminiferous tubules associated with PTU-induced increases in testicular size and sperm production demonstrates that increases in Sertoli cell numbers result in increased sperm production and supports the idea that SERToli cells are the major regulators of the magnitude of sperm production.
