Background The highly sensitive period of preimplantation development represents that embryo is very vulnerable to exogenous agents. Many of the developmental abnormalities may arise from the inevitable maternal periconceptional exposures to toxic substances in the environment which may threaten reproductive capability and pregnancy outcomes. In this article, an overview of the association betw...

In view of the persistent claim of Australian Vietnam veterans that their health and that of their children were adversely affected, aspects of reproductive behaviour and the distribution of disease and disability in family units were investigated in a sample of Tasmanian veterans and another group chosen for comparison of selected characteristics. One third of veterans reported serious health ...

The male reproductive system includes the gonads (testes), a series of specialized ducts (the epididymis, ductus deferens, ejaculatory duct, and urethra), accessory glands (the seminal vesicles, prostate, and bulbourethral glands), and the external genitalia (penis and scrotum). The female reproductive system includes the gonads (ovaries), derivatives of an embryonic system of ducts (the uterin...

objective: in this study we investigated the effects of spearmint (mentha spicata labiatae) on the reproductive system, fertility and number of offspring in adult male rats. materials and methods: adult wistar male rats in one control (c) and three experimental groups (i, ii and iii) received 0, 10, 20 and 40 mg/kg spearmint extract orally for 45 days, respectively.  following this treatment, t...

The male reproductive system (Figure 1) consists of a series of glandular, muscular, and ciliated tubes and diverticula dedicated to the production, storage, nourishment, and activation of spermatozoa, and to their transport into the female reproductive tract. There are three products of the system: the germ cells, the seminal fluid that bathes them when they are emitted, and hormones that regu...
