Correlations in family size across generations could have a major influence on human population size in the future. Empirical studies have shown that the associations between the fertility of parents and the fertility of children are substantial and growing over time. Despite their potential long-term consequences, intergenerational fertility correlations have largely been ignored by researcher...

Introduction Fertility is a very complex trait, difficult to define, to record and to evaluate all the factors that influence fertility. Fertility is strongly influenced by environmental effects and in part by genetics, the male for fertilization and the female for conception. In general, the fertility trait is hereditary but only to a small degree. There does however exist sufficient genetic v...

Rat protein DE is an androgen-dependent cysteine-rich secretory protein (CRISP) synthesized by proximal epididymal regions. DE, also known as CRISP-1, is localized on the equatorial segment of acrosome-reacted spermatozoa and participates in gamete fusion through binding to egg complementary sites. Immunization of rats with DE inhibits fertility and sperm fusion ability, suggesting that DE repr...

Background: Curcumin is an active constituent, obtained from rhizome of Curcuma longa linn, known to have broad medicinal properties, was studied for its effect on fertility in female rats. has anti-ovulatory probably by antiestrogenic activity through suppression negative feedback estrogen pituitary.Methods: Inbred Charles Foster albino rats (150-180 gm) were used study. They divided into diff...

Radiotherapy is one of the standard cytotoxic therapies for cancer. However, it has a profound impact on ovarian function leading to premature ovarian failure and infertility. Since none of the currently available methods for fertility preservation guarantees future fertility, the need for an effective radioprotective agent is highly intensified. The present study investigated the mechanisms of...

BACKGROUND High-density lipoprotein (HDL) appears to be the dominant lipoprotein particle in human follicular fluid (FF). The reported anti-atherogenic properties of HDL have been attributed in part to reverse cholesterol transport. The discoveries of the scavenger receptor class B type I (SR-BI) and the ATP-binding cassette A1 lipid (ABCA1) transporter have generated studies aimed at unravelin...
