Background: Many health problems are related to lifestyle and dietary factors. Increasing trend in reproductive disorders observed in recent years may be associated at least in part with these factors, which are compounded by some of the new emergent life styles. Materials and Methods: The data available suggests that lifestyle factors asuch as obesity, tobacco smoking or chewing, alcohol and s...

Reproductive health problem is more common nowadays and various causes like nutritional defect, socio-economic problems, life style changes are reason for that, among those reason, one important factor is environmental factor. In this study, the pesticide, Lindane is used to induce reproductive toxicity and the levels of male reproductive hormone, antioxidant and histopathology of rat testis wa...

The reproductive system is extremely susceptible to environmental insults, for example exogenous steroids during gestational development and differentiation. Experimental induction of androgen excess during prenatal life in female animal models reprograms their reproductive physiology, however the fetal programming of the male reproductive system by androgen excess has not been well studied. We...

Sexually selected traits are predicted to show condition dependence by capturing the genetic quality of its bearer. In separate-sexed organisms, this will ultimately translate into condition dependence of reproductive success of the sex that experiences sexual selection, which is typically the male. Such condition dependence of reproductive success is predicted to be higher in males than female...

Nesfatin-1, an anorexic nucleobindin-2 (NUCB2)-derived hypothalamic peptide, controls appetite and energy metabolism. Recent studies show that nesfatin-1/NUCB2 is expressed not only in the brain but also in gastric and adipose tissues. Thus, we investigated the distributions of nesfatin-1/NUCB2 in various tissues of male and female mice by real-time PCR, western blotting, and immunohistochemica...

BACKGROUND Functional male gametes are produced through complex processes that take place within the testis, epididymis and female reproductive tract. A breakdown at any of these phases can result in male infertility. The production of mutant mouse models often yields an unexpected male infertility phenotype. It is with this in mind that the current review has been written. The review aims to a...

Understanding of the development of the reproductive organs is essential to the evaluation of abnormalities in sexual differentiation. Recent advances resulting from application of genetic, biochemical, and ultrastructural techniques have helped to clarify the mechanisms regulating gonadal and reproductive tract development. The present review considers the major processes of sexual differentia...

Introduction: Wistar rats are an outbred strain of albino rats belonging to the species Rattus norvegicus. Histopathological studies on the testis was carried out to determine the effects of heat and lead on male fertility by evaluating some andrological parameters of the wistar rat such as morphology of spermatozoa, sperm count and motility. The main objective of this research was to compare t...

We investigated chromosomal instability in peripheral blood lymphocytes (PBL) of patients with reproductive failure in respect to age, smoking habits, gender, miscarriages, and semen parameters. The study involved 36 individual cases of reproductive failure (18 men and 18 women) attended at the Clinical Centre of Kragujevac, Serbia, and 30 healthy subjects (15 men and 15 women). Micronuclei (MN...

We mapped the cellular expression of estrogen receptor (ER) and ER mRNAs in the male reproductive system of the rat during development and adulthood by in situ hybridization. The expression patterns of ER mRNA in the gonad, efferent duct and initial segment of the epididymis during the perinatal period were essentially similar to those of the adult: ER mRNA signals were expressed most intensely...
