For over 15 years, reproductive toxicologists have explored the physiological outcomes and mechanism of fetal phthalate exposure to determine the risk posed to human male reproductive health. This review examines the fetal male reproductive system response to phthalate exposure across species including rat, mouse, and human, with emphasis on the testis. In the rat, in utero phthalate exposure c...

Abstract Background Anti-Müllerian hormone is a dimeric glycoprotein produced by the granulosa cells of preantral and small antral follicles ovaries. It reliable biomarker ovarian reserve, ageing, response in management women with infertility. However, there are few studies on determinants serum anti-Müllerian Nigerian women. This study aimed to investigate among adult reproductive age. The was...

BACKGROUND Rodent and in vitro studies have demonstrated the estrogenicity of bisphenol A (BPA). However, few studies have examined the relationship between human exposure to BPA and male reproductive function. OBJECTIVES We investigated the relationships between environmental BPA exposure and reproductive parameters, including semen quality and male reproductive hormones, in prospectively re...

The vast majority of species are excluded fromhuman-dominated landscapes, but some species persist and appear to thrive, despite facing challenges they would not encounter in less disturbed habitat. Corticosteroid (cort) secretion may play a significant role in enabling an animal to cope with urban breeding habitat because it helps mediate physiological and behavioral responses to environmental...

OBJECTIVES A number of factors involved in the control of energy balance and metabolism act as modulators of gonadal axis. Ghrelin, a peptide secreted from the stomach and hypothalamus, has emerged as an orexigenic food intake controlling signal acting upon hypothalamus. Recently, the potential reproductive role of ghrelin has received great attention. This study was designed to investigate the...

We present 2 cases of likely rare event. In case 1, 3rd degree consanguineous marriage revealed inv(6) with same break points in parents who were found to be phenotypically normal. The same inv(6) being inherited in progeny but presented with low AMH (anti Mullerian hormone) and high level of FSH (follicular stimulating hormone) leading to polycystic ovarian syndrome/premature ovarian failure. ...

a:4:{s:10:"Background";s:391:"Unusual effect of celecoxib may be seen in some patients that have used this drug for a long time. Celecoxib is a form of non-steroidal anti-inflammatory drug (NSAID) that directly targets COX-2, an enzyme responsible for inflammation and pain which is the main feature of celecoxib. The goal of this survey is to assess the effect of celecoxib on male-reproductive s...

apparent rise in the incidence of infertility in females and the trend shifting towards delayed child bearing brought up the concept of ovarian ageing. women in their early thirties show poor ovarian reserve which is an entity named as early ovarian ageing. early ovarian ageing is mostly genetically determined, but acquired modifiable factors like smoking, or ovarian surgery have some roles. in...

Reproductive behaviour of animals requires a well-adapted muscular system. This study examines the structural and functional development of ovipositor muscle properties in female locusts during reproductive development. A possible regulation by juvenile hormone (JH) was assessed by comparing muscle properties in immature and mature females and with those whose JH production was inhibited by all...

In many animal societies, dominant individuals monopolize reproduction, but the tactics they employ to achieve this are poorly understood. One possibility is that aggressive dominants render their subordinates infertile by inducing chronic physiological "stress." However, this hypothesis has been discarded largely for cooperatively breeding species, where reproductive monopolies are often extre...
