What is a risk associated with the use of 17 hydroxyprogesterone caproate?

The choice of possible hypospadias in male offspring as a risk associated with the use of 17-hydroxyprogesterone caproate is rooted in the implications of hormonal exposure during pregnancy. 17-hydroxyprogesterone caproate is utilized primarily as a preventative measure for preterm birth, especially in women with a history of spontaneous preterm birth. Studies have suggested that exposure to synthetic progestins, including 17-hydroxyprogesterone caproate, during critical periods of development may influence the reproductive system, particularly in male fetuses.

Hypospadias is a condition where the opening of the urethra is not located at the tip of the penis, which can be impacted by the hormonal environment in utero. The mechanism is not entirely clear, but there is an association observed between the use of certain hormonal therapies in pregnancy and the occurrence of urogenital defects in male offspring. This highlights the importance of considering the potential impacts of medications used for the management of pregnancy complications on fetal development.

Understanding this risk underscores the need for careful evaluation and monitoring when prescribing such treatments during pregnancy, as well as the importance of counseling for expectant parents regarding possible outcomes.
