Spermatogenesis, a study of germ cell development, is a long, orderly, and well‐defined
process occurring in seminiferous tubules of the testis. It is a temporal event whereby …

The still apt definition of a placenta is that coined by Mossman, namely apposition or fusion
of the fetal membranes to the uterine mucosa for physiological exchange. As such it is a …

Male gametes are generated through a specialised differentiation pathway involving a
series of developmental transitions that are poorly characterised at the molecular level …

Little is known of the molecular mechanisms whereby spermatogonia, mitotic germ cells of
the testis, self-renew and differentiate into sperm,. Here we show that Zfp145, encoding the …

Mammalian spermatozoa become motile at ejaculation, but before they can fertilize the egg,
they must acquire more thrust to penetrate the cumulus and zona pellucida. The forceful …

Bisphenol A (BPA) is a commercially important high production chemical widely used in
epoxy resins and polycarbonate plastics, and is ubiquitous in the environment. Previous …

It has been widely held that all that fathers essentially contribute to the next generation is
half their genome. However, recent progress towards understanding biological processes …

Prior to the pairing and recombination between homologous chromosomes during meiosis,
telomeres attach to the nuclear envelope and form a transient cluster. However, the protein …

Spermatogenesis in adult mammals is highly organized, with the goal being continual sperm
production. Vertebrate testes are arranged into recurring cellular associations that vary with …

This review describes the regulation of spermatogenesis taking into consideration the
hypothalamic–pituitary gonadal axis, the male reproductive organs and the endocrine and …
