Epididymis 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...

Inhibition of In Vitro Fertilizing Capacity of Cryopreserved Mouse Sperm by Factors Released by Damaged Sperm, and Stimulation by Glutathione

BACKGROUND In vitro fertilization (IVF) of eggs by frozen and thawed C57BL/6J mouse sperm is inhibited by dead sperm and enhanced by preincubation of the sperm in calcium-free medium. In other species, the presence of sperm killed by freezing and thawing has been associated with the generation of hydrogen peroxide. METHODOLOGY/PRINCIPAL FINDINGS The proportion of eggs fertilized by cryopreser...

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...

Evaluation of Fertilizing Capacity of Rabbit Sperm on the Basis of Annexin V-labelled Membrane Changes

The aim of this study was (1) to analy�e fresh intact or differently influenced rabbit sperm samples, using Annexin V–binding method for the detection of membrane phosphatidylserine translocation, and (2) to estimate obtained results in relation to the conceptional rate of rabbit females fertili�ed with semen from different groups. Following sample groups were designed: 1. freshly collected sem...

Evaluation of Fertilizing Ability using Frozen Thawed Sperm in the Longtooth Grouper, Epinephelus bruneus

This study examines the effects on fertilization rate (FR), hatching rate (HR), and normal individual rate after artificial fertilization using frozen thawed sperm according to the cryoprotectant (DMSO) concentration and the period of cryopreserved sperm of longtooth grouper, Epinephelus bruneus. Performing artificial fertilization using frozen-thawed sperm, after freezing the sperm at differen...
