I would have to know more about your history to ascertain whether Finasteride is a cause of decrease of your sex drive. For example: 1. How long have you been taking Finasteride? 2. Do you have a history of sexual dysfunction? Also, you are in your hair transplant recover period and that may be affecting you as well. These are some of the things you should speak with your hair restoration doctor about.I have seen and treated about 2,000 men with Finasteride and the vast majority do not complain of sexual dysfunction. It has been shown in a very small percentage to reduce interest in sex for about a 6 week period but return to normal after 6 weeks. It does in fact raise circulating testosterone and reduces circulating DHT. If further interested read the link below from PubMed. But most importantly discuss this matter with your doctor. Finasteride will save and regrow hair in your crown area and without it you may lose a lot more hair.
You may lose some your non transplanted hair. The best hair results come from transplants and Finasteride as usually less non transplanted hair is lost.
