Sperm Proteomics: Road to Male Fertility and Contraception
Spermatozoa are highly specialized cells that can be easily obtained and purified. Mature spermatozoa are transcriptionally and translationally inactive and incapable of protein synthesis. In addition, spermatozoa contain relatively higher amounts of membrane proteins compared to other cells; therefore, they are very suitable for proteomic studies. Recently, the application of proteomic approac...
متن کاملMale Contraception
Very few options for men to initiate fertility control are currently available. Due to the potential public health impact of a novel method of contraception for men in the developed and developing world, a number of organizations are conducting or supporting studies which focus on the male contraceptive aspect of reproductive health. These include bilateral and multilateral donors, national gov...
متن کامل[Male contraception].
Clear evidence shows that many men and women would welcome new male methods of contraception, but none have become available. The hormonal approach is based on suppression of gonadotropins and thus of testicular function and spermatogenesis, and has been investigated for several decades. This approach can achieve sufficient suppression of spermatogenesis for effective contraception in most men,...
متن کاملEffect of Astaxanthin on Human Sperm Capacitation
In order to be able to fertilize oocytes, human sperm must undergo a series of morphological and structural alterations, known as capacitation. It has been shown that the production of endogenous sperm reactive oxygen species (ROS) plays a key role in causing cells to undergo a massive acrosome reaction (AR). Astaxanthin (Asta), a photo-protective red pigment belonging to the carotenoid family,...
متن کاملEffect of Hypotonic Stress on Ornithine Decarboxylase
This report examines the effect of hypotonic stress on ornithine decarboxylase (ODC) activity and ODC mRNA concentrations in LLC-PKI cells. Earle’s balanced salts solution minus glucose (EBSS-G) with decreasing concentrations of NaCl was utilized as the ODC induction medium. Hypotonic EBSS-G increased both the concentration of ODC mRNA and the specific activity of ODC in LLC-PKl cells. Actinomy...
