The profound architectural changes that transform spermatids into spermatozoa result in a
high degree of DNA packaging within the sperm head. However, the mature sperm …

Objective To follow-up and expand discussion on the action mechanisms of antisperm
antibodies in human infertility, the etiology and control of antisperm antibody induction …

The existence of a complex population of mRNA in human sperm is well documented but
their role is not yet elucidated. Using discontinuous density gradients, we have isolated high …

This review emphasizes the comparative approach for developing insight into knowledge
related to cellular communications occurring in the hypothalamus–pituitary–gonadal axis …

The population explosion, unintended pregnancies, sexually transmitted diseases, and
cancer (cervical and breast) continue to cause major public health issues worldwide …

Round spermatids contain high levels of extremely varied mRNAs that are synthesized
either throughout early spermatogenesis or during spermiogenesis from the haploid …

Recombinant (r) fertilization antigen (FA)-1 was investigated for its immunocontraceptive
effect using the mouse as a model. Active immunization with the murine rFA-1 antigen raised …

BACKGROUND: Male infertility is the major cause of conception failure in about 25% of all
infertile couples. Understanding the causes of male infertility depends to a certain extent on …

Although it is well known that mRNA is present in mammalian spermatozoa, the relevance of
mRNA to capacitation and early embryo development in the pig remains unclear. In the …

Testicular morphology of vertebrate testis indicates requirement of local control. In urodeles,
the testis is organized in lobes of increasing maturity throughout the cephalocaudal axis …
