in wistar rats, reproductive behavior is controlled in a neural circuit of ventral forebrain including the medial amygdala (me), bed nucleus of the stria terminalis (bnst) and medial preoptic area (mpoa) via perception of social odors. diabetes mellitus (dm) is a widespread metabolic disease that affects many organs in a variety of levels. dm can cause central neuropathies such as neuronal apop...

immune infertility, in terms of reproductive failure, has become a serious health issue involving approximately 1 out of 5 couples at reproductive age. semen that is defined as a complex fluid containing sperm, cellular vesicles and other cells and components, could sensitize the female genital tract. the immune rejection of male semen in the female reproductive tract is explained as the failur...

Basic understanding of the male reproductive system is fundamental in effective evaluation and treatment of male infertility. This chapter is a concise introduction to the male reproductive anatomy and the intricately designed process of spermatogenesis along with its hormonal control.

-The Texas Platycynorta transversalis is regarded as a junior synonym of V . sayi. Karyotypes of male and female V. sayi from central Texas reveal 2n = 78. This number is almost twice that previously reported for any other harvestman. The male reproductive system of V. sayi is described and illustrated. Natural history data are provided for egg laying and developmental times. The supercooling p...

Paper presents the first description of the so far unknown sexual generation of Pterocomma tremulae (Aphididae, Aphidinae): oviparous female and alate male. It also provides detailed description of the male reproductive system. Discussion focuses on comparative analysis of male reproductive system with other aphid groups and possible importance of its structure in resolving phylogenetic interre...

As demonstrated in past studies, androgens appear to play critical roles in regulating reproduction in male sharks. However, little is known about the cell-specific actions of androgens in these fishes. To address this, this study examined androgen targets in reproductive organs of a seasonally reproducing shark, the bonnethead (Sphyrna tiburo). A partial bonnethead AR cDNA clone was isolated a...

Male infertility is directly or indirectly responsible for 60% of cases involving reproductive-age couples with fertility-related issues. Nevertheless, the evaluation of male infertility is often underestimated or postponed. A coordinated evaluation of the infertile male using standardized procedures improves both diagnostic precision and the results of subsequent management in terms of effecti...

Background: We have recently shown that human embryonic (hESCs) and induced pluripotent stem cells (hiPSCs) can differentiate into advanced spermatogenic cells including round spermatids by in vitro culture (Easley et al., Direct differentiation of human pluripotent stem cells into haploid spermatogenic cells. Cell Reports 2, 440-446 2012) and also, in collaboration, that rhesus spermatogonial ...

Diesel exhaust particles (DEPs) are particulate matter from diesel exhaust that contain many toxic compounds, such as polyaromatic hydrocarbons (PAHs). Some toxicities of PAH are thought to be expressed via aryl hydrocarbon receptors (AhRs). The male reproductive toxicity of DEPs might depend on AhR activation induced by PAHs. We hypothesized that AhR antagonists protect against the male reprod...
