Prenatal testosterone transfer refers to the transfer of testosterone from a mother to her unborn child. It is important for the development of the fetus, but excessive levels of testosterone can lead to various developmental and behavioral problems. Synonyms for this term include prenatal androgen transfer, maternal androgen transfer, and fetal testosterone exposure. These terms are used interchangeably in research studies exploring the effects of testosterone on prenatal development. Understanding the impact of prenatal testosterone transfer is vital for identifying and addressing any potential health issues that may arise as a result of altered hormone levels in utero.
