To review, the human testis lies within the scrotum. The "sex cords" of the early embryo become follicles in the female ovary and seminiferous tubules in the male testes (Figs. 1.3 , 1.4 , and 1.5 ). The Sertoli cells in the seminiferous tubules are equivalent to the granulosa cells in...

The steroid composition of and steroid conjugation in human cadaver and boar testes were investigated by analyzing the endogenous steroids. Gas-liquid chromatography and gas chromatography-mass spectrometry were used to identify the steroids and to determine the position of the sulfate group in sulfate...
An endocrine gland is an organ in the human body, which produces hormones that are released directly into the blood of the organisms. The endocrine glands are the ductless glands. The different endocrine glands are distributed throughout the body including thyroid, parathyroid, testes, ovaries, hy...
The down-regulation of miR-141 and 429 coincides with the progression of testis development in both yellow catfish and human. At last, the expression pattern of nine arbitrarily selected miRNAs detected by quantitative RT-PCR was consistent with the Solexa sequencing results. Our study provides a...

In the preceding paper 1 , cytological evidence is presented to show that in 'sex-reversed' XX male mice 2 the sex-reversing factor, Sxr , is carried on a dark-staining body located on the distal end of the paternal X chromosome. The X-... BM Cattanach,EP Evans,MD Burtenshaw,... ...
