Propecia Overview

Propecia is a prescription medication used for the treatment of male pattern baldness. It contains 1-mg of finasteride, a medication that was originally used to reduce enlarged male prostate. Since Propecia was approved by the FDA in 1998, it has been used by millions of men. Unfortunately, more and more men are complaining of severe Propecia side effects that persist even after they stop taking the medication.

Propecia works by inhibiting an enzyme called 5-alpha reductase. Normally, 5-alpha reductase is used to regulate hormones in a man’s body. It converts testosterone into dihydrotestosterone (DHT). In man with male pattern baldness, exposure to DHT caused them to lose their hair. Propecia inhibits 5-alpha reductase, which decreases the amount of DHT by 70-80%.

When DHT is inhibited, more testosterone is converted into estrogen. Increased amounts of estrogen can lead to many types of harmful sexual side effects, including problems with erections, loss of interest in sex, less ejaculate volume, growth of male breast tissue (gynecomastia), and more. Even more troubling, many these are now reporting that these side effects do not resolve once they stop taking Propecia.

Propecia and Gynecomastia

High levels of estrogen in a man’s body can lead to gynecomastia, or enlarged male breast tissue. When Merck initially started selling Propecia, gynecomastia was not listed as a potential side effect, and Merck stated that there was no scientific evidence linking 1-mg finasteride to gynecomastia.

However, after Propecia was sold and used by millions of men, there were more and more reports of men suffering from gynecomastia. The warning label now includes information about this risk, but not about the risk of persistent gynecomastia, despite evidence that this is a side effect of Propecia.

In fact, there is strong evidence that finasteride can cause persistent gynecomastia. In this study, one patient who stopped taking finasteride had enlarged breast tissue 10 months later. Another patient who stopped taking finasteride had enlarged breast tissue 6 years later.


Gynecomastia is the non-cancerous growth of male breast tissue. It is not the same as fat deposits in the breast area caused by obesity. Gynecomastia is a separate condition that often occurs due to a hormonal imbalance which causes enlargement of glandular tissue in “cone-shape” around the male nipple. During a physical examination, a doctor can diagnose gynecomastia because it is firmer than fat deposits.

Gynecomastia is not life-threatening. However, it can cause to feel like he has a permanent physical disfigurement. This can cause untold amounts of psychological distress and suffering, social anxiety, and embarrassment. Furthermore, enlarged male breasts are often very sensitive and even painful at times, causing physical discomfort.

Studies of Propecia and Gynecomastia

In June 1995, The American Journal of the Medical Sciences published a study regarding the link between finasteride and gynecomastia. The researchers who authored the study were concerned that doctors were not discussing the risk of gynecomastia with their patients. They warned that gynecomastia is a serious but often overlooked side effect of finasteride. They also warned that there need to be more studies of finasteride and gynecomastia to assess the actual risk of persistent gynecomastia.

In the report, the researchers described several cases of gynecomastia in several men taking finasteride. One was a 62 year-old man who was taking finasteride to reduce his enlarged prostate. Doctors found that the man had suffered a massive change to his endocrine system, including a significant decrease in DHT levels with an increased ratio of estrogen.

The researchers also described the cases of two men who had suffered persistent gynecomastia after stopping finasteride. One had enlarged breasts 10 months after stopping finasteride, and the other had enlarged breasts for 6 years after stopping finasteride.

The researchers warned that finasteride patients should be closely monitored for this side effect.
