Abstract:
Over the past decade many publications attest to the substantial increase in public and scientific concern regarding the potential of industrial and environmental chemicals to interfere with male reproductive function. Spermatogenesis, (the process of sperm formation) depends on a series of complex biological interactions which can be interrupted at various stages by chemical insult. Recently a number of these chemicals have been used experimentally to directly disrupt testicular function to provide an insight into the processes involved in normal spermatogenesis. Based on these investigations

Patterns of methylation at the 5-position of cytosine are postulated to be involved in several mammalian processes such as the regulation of gene expression, genomic imprinting and X chromosome inactivation.

The establishment of methylation patterns is believed to be initiated during gametogenesis and continue during early embryonic development.

Abstract:
Spermatogenesis takes place in the seminiferous epithelium and it is a tightly regulated process that produces spermatozoa from spermatogonia. During spermatogenesis, germ cells have to traverse the seminiferous epithelium, from basal to adluminal compartment and finally reach the luminal edge of the seminiferous tubules at spermiation. During the transit of germ cells, they have to get across the blood-testis barrier (BTB), which is formed by adjacent Sertoli cells. Thus, although BTB is considered as one of the tightest blood-tissue barrier, the BTB undergoes cyclic restructuring to “open”

Abstract:
Approximately 131 million Chlamydia trachomatis infections occur annually. The rates of infection are similar between males and females, but female infections have been more widely characterised. C. trachomatis causes infertility in men and women but little is known about the male disease. This study investigated the ability of chronic infections to cause male infertility. In mice, Chlamydia colonises specialised testicular cells, resulting in partial destruction of the testicular structure and production of anti-sperm-antibodies.
