RANTES and human sperm fertilizing ability: effect on acrosome reaction and sperm/oocyte fusion.
Beta-chemokine, regulated on activation and normally T-cell expressed and presumably secreted (RANTES), is present in both the male and female genital tract fluids where its levels increase in diseases related to infertility, such as endometriosis and male genital tract infections. beta-Chemokine receptors (CCR3 and CCR5) are expressed on freshly ejaculated human sperm cells and a sperm chemoat...
متن کاملEpididymis cholesterol homeostasis and sperm fertilizing ability.
Cholesterol, being the starting point of steroid hormone synthesis, is a long known modulator of both female and male reproductive physiology especially at the level of the gonads and the impact cholesterol has on gametogenesis. Less is known about the effects cholesterol homeostasis may have on postgonadic reproductive functions. Lately, several data have been reported showing how imbalanced c...
متن کاملLipid peroxidation was associated to the impairment of the fertilizing capability of gilthead sperm exposed to surfactants.
The present study was designed to determine whether lipid peroxidation was associated with the impairment of the fertilizing capability of gilthead sperm after acute exposure to anionic surfactant Sodium Dodecyl Sulphate (SDS). Spawned eggs and sperm were collected from adult giltheads. Sperm suspensions (100,000,000 spermatozoa/mL) were dosed separately with different concentrations of SDS (0....
متن کاملEffect of Extenders and Temperatures on Sperm Viability and Fertilizing
In this study the effect of extenders and temperatures on sperm viability and fertilizing capacity of boar sperm during long-term storage was investigated. Acrosomal integrity, membrane integrity, motility and hypo-osmotic resistance were evaluated by fluorescence and light microscopy. An in vitro fertilization test was performed to assess the fertilizing capacity of stored spermatozoa. The fiv...
متن کاملProtein tyrosine phosphorylation of the human sperm head during capacitation: immunolocalization and relationship with acquisition of sperm-fertilizing ability.
The occurrence of tyrosine phosphorylation (TP) in the sperm head during capacitation has been poorly investigated, and no data exist on the relationship of its dynamics with the acquisition of sperm fertilizing ability. This study localized TP of head proteins in human spermatozoa during capacitation and explored its relationship with acquisition of the ability to display progesterone (P)-stim...
