I Think My Sperm Count is Lower After Using Propecia for 5 Weeks

It has been 5 weeks since i started propecia, i think my sperm count and density as well might have decreased a bit, should i keep on using the medication? No loss of libido though.

A known side effect of finasteride (Propecia) is a reduced volume of ejaculate and this occurs in somewhere between 10-20% of patients, but all of these men will have a normal sperm count when tested for their actual count. You may be confusing ejaculate volume (which is often lower when taking the drug) to sperm count (usually range is in the 15-60 million per cc). There is more to sperm being present that is important. One looks at the health of the sperm (morphology), the motility of it, the sugar (fructose) in the fluid, etc.

If you want to know if you have azoospermia (no sperm in the semen) then you can get your doctor to recommend that you be tested. There are some rare reports and concerns that finasteride can reduce the actual sperm count and even produce sterility if the azoospermic counts go down to very low numbers. When this happens, the process often reverses when you stop taking finasteride.
