Bacteria, parasites, viruses and fungi are some important clinical pathogens that may cause the microbial infections of male reproductive tracts, and also interfere with the reproductive function in male [2]. 15% of the cases of male infertility are due to reproductive tract inflammations and infections [3]. Several organs of the male reproductive system, such as male accessory sex glands, test...

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...

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...

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...

OBJECTIVE Analysing scientific publications about male sexual and reproductive health in Colombia during the last two decades and determining the main findings about knowledge regarding the topic in Colombia. METHODOLOGY A systematic review was made of scientific publications in international databases concerned with male sexual and reproductive health in Colombia. Inclusion criteria concerne...

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...

Ginseng is often referred to as the King of all herbs, and is found to be a promising agent to improve general well-being. Ginseng has also been reputed as an aphrodisiac, and is used to treat sexual dysfunction as well as to enhance sexual behavior in traditional Chinese medical practices. Data from animal studies have shown a positive correlation among ginseng, libido, and copulatory performa...

OBJECTIVE To evaluate the health effects of parental dietary exposure to GM rice TT51 on the male reproductive system of rat off spring. METHODS Rice-based diets, containing 60% ordinary grocery rice, MingHui63, or TT51 by weight, were given to parental rats (15 males/30 females each group) for 70 days prior mating and throughout pregnancy and lactation. After weaning, eight male offspring ra...

In dioecious plants, reproductive efforts of male and female plants can be differentially affected by herbivory due to sex-specific allocation and re-modulation of resources. Here, we investigate the effects of foliar herbivory by the polyphagous species Spodoptera littoralis (Boisduval) (Lepidoptera: Noctuidae) on male and female reproductive traits of Silene latifolia (Poir.) (Caryophyllaceae...
