Q: I have low sperm motility and the doctor advised me take testoviron injection. But my doctor, by mistake, gave me Susten (progesterone) 100 mg instead of Sustanon 100 twice in two weeks. I know Susten is a female drug to be taken during pregnancy. I just want to know will it have adverse effects if administered to a male.

A:Susten is a progesterone, a female hormone. It is not to be used during pregnancy in females. Prolonged use can adversely affect if wrongly given to males but very short term use will not produce any lasting side effects. Testoviron (testosterone) is to be administered only if there is documented deficiency of the hormone in males. Otherwise it can actually decrease fertility.
