The effects of two environmental endocrine disruptors, the synthetic pharmaceutical estrogen 17-ethinylestradiol (EE) and bisphenol-A (BPA), were analysed in male and female rats in a very sensitive developmental period, puberty. Immunohistochemistry was used to evaluate changes in the number of ...

Men are born with immature male organs and, with the onset of puberty, hormonal changes occur that allow sperm to begin to be generated. Inside the testicles, in structures called seminiferous tubules, sperm will be produced permanently. Subsequently, the sperm are transported through the vas defe...
advanced age at childbearing, rising childlessness and a lower number of children. As reproduction shifts to later ages, genetic factors may become increasingly important. Although monogenic genetic effects are known, the genetics underlying human reproductive ...

This is when the boy's voice suddenly and uncontrollably changes pitch mid-word or sentence, due to the growth of the larynx and the lengthening of the vocal cords. Stage four of male puberty commonly takes place when a boy is around 14 or 15 years old. Hair begins showing up in the ...

All people assigned male at birth have a male reproductive system, but it doesn't come fully function until puberty, which typically starts more than 10 years after birth. Unlike the female reproductive system, much of the male reproductive system is on the outside of the body. The male sex...
However, in tests with a sexually receptive female as partner, the group treated with E during puberty and adolescence showed a far higher frequency of mounting and intromission-like behaviors than controls. In tests for sexual approach behavior, these females approached other females more than ...
Gestational hypoxia impacted female offspring during puberty more than males, whereas it impacted male offspring during young adulthood more than females. These novel findings demonstrate that hypoxic insults during pregnancy mediate developmental programming of the cortical and subcortical pathways, in which...
