Question

Quizplus · Accepted Answer

The descent of the testes is influenced by changes in the relative growth rates of the intra-abdominal structures, specifically the gubernaculum and the inguinal canal. This process usually occurs during the third trimester of fetal development but can continue for several months after birth. Hormones such as testosterone and insulin-like factor 3 also play a role in this process, but FSH and LH are not directly involved in the descent of the testes.
