Exposure to plasticizers di(n-butyl) phthalate (DBP) and diethylhexyl phthalate (DEHP) during sexual differentiation causes male reproductive tract malformations in rats and rabbits. In the fetal male rat, these two phthalate esters decrease testosterone (T) production and insulin-like peptide 3 (insl3) gene expression, a hormone critical for gubernacular ligament development. We hypothesized t...

The plainfin midshipman fish, Porichthys notatus, is a seasonal breeding teleost fish for which vocal-acoustic communication is essential for its reproductive success. Female midshipman use the saccule as the primary end organ for hearing to detect and locate "singing" males that produce multiharmonic advertisement calls during the summer breeding season. Previous work has shown that female aud...

Individuals of species inhabiting temperate and boreal latitudes optimize the timing of energetically costly processes by curtailing nonessential energetically demanding processes when environmental conditions are not favourable. One proximate environmental variable used to fine-tune moment-to-moment changes in reproductive physiology and behaviour is food intake. The neuroendocrine mechanisms ...

Even in the days of Galen and Vesalius, cerebral appendage was viewed as an organ whose task is to excrete some products. very dark for their purpose. It only since creation doctrine internal secretion by Brown-Squard that facts began accumulate determined actual place pituitary gland group endocrine glands indicated its enormous physiological pathological significance human body. One main intr...

Placenta is a unique organ, without which the very phenomenon of human pregnancy impossible. Semiallogeneous nature, localization placenta, complex and heterogeneous cellular composition determines its multifaceted role in course physiological pregnancy, indicates importance studying this organ number reproductive pathologies. The purpose review was to analyze literature sources illustrating en...

Egg-induced lesions in the upper and the lower female reproductive tract are important complications of the infection with Schistosoma mansoni. The understanding of the pathophysiology and pathology of genital lesions is only rudimentary, simple and reliable diagnostic tools are not at hand, epidemiological data do not exist and how to treat best the women affected, is not known. In view of rec...
