BACKGROUND Functional male gametes are produced through complex processes that take place within the testis, epididymis and female reproductive tract. A breakdown at any of these phases can result in male infertility. The production of mutant mouse models often yields an unexpected male infertility phenotype. It is with this in mind that the current review has been written. The review aims to a...

Background: Mammals utilise an XX/XY system of sex determination in which the Y-linked gene SRY (Sexdetermining region Y) exerts a dominant masculinising influence on sexual development. Sex chromosome homology and comparative sequence studies suggest that SRY evolved from the related SOX3 gene on the X chromosome, although there is no direct functional evidence to support this hypothesis. The ...

The goal of this video study was to investigate whether the gender composition a pair influences collaboration during programming process. Pair is an agile software development technique in which two people share computer and jointly develop program. One programmers, driver, operates keyboard mouse; other, navigator, reviews code helps without touching or mouse. These roles are swapped at regul...

The presence of cytochrome P-450 and associated mono-oxygenase activities was examined in brain microsomes from male and female mice. Although the cytochrome P-450 level in male mouse brain was very low as compared with mouse liver, the aminopyrine N-demethylase and morphine N-demethylase specific activities in male mouse brain were much higher than those observed in mouse liver. Ethoxycoumarin...
