Penis in womb
Link to research DOI : Proper development of the fetal penis requires not just testosterone from the testes, but a second hormone produced by other tissues, including the placenta, according to a new study publishing February 14 in the open-access journal PLOS Biology from Paul Fowler of the University of Aberdeen, Michelle Bellingham of the University of Glasgow, and colleagues in the UK, France and Sweden. The results reveal a previously unknown pathway of masculinization of the external genitals, and may explain why placental dysfunction is associated with disorders of male genital development. However, the details of this backdoor pathway, including the source of the DHT precursor, have been unclear. To learn more about this pathway, the authors used mass-spectrometry to measure levels of different steroids in fetal plasma and tissue during the second trimester, when the most critical steps in penis development occur.

NCBI Bookshelf. Sex differences of importance to health and human disease occur throughout the life span, although the specific expression of these differences varies at different stages of life. Some differences originate in events occurring in the intrauterine environment, where developmental processes differentially organize tissues for later activation in the male or female. In the prenatal period, sex determination and differentiation occur in a series of sequential processes governed by genetic and environmental factors.

Scientists have shed light on the process that causes the penis to form in the womb, in research that brings us closer to understanding why some babies are born with genital defects. We already know that a fetus' testes need to give off the hormone testosterone so the penis can form in the womb. Now, an international team of researchers has presented a new piece of the puzzle, by building on previous research indicating another or "backdoor process takes place that also results in DHT being created independent of the testes. They think this happens in non-genital tissue like the placenta. Of the androgens hormones including testosterone, DHT, and androstenedione found in the circulatory system of male fetuses, androsterone was the principal androgen in the backdoor process, the authors wrote.
How deep is the cervix? As health advocates but not doctors , we're asked this question all the time. Where is the cervix and how do I know if mine is low or high? The real answer to these questions is: It depends. We come in all different shapes and sizes inside and out.
