In terms of orgasm sensation, it’s the difference between having a full-course dinner and just having a puny little appetizer. But I have a HUGE interest in still having great ejaculations (“semen”). I have no interest in fathering a child (“sperm”) at this point in my life. Urologist couldn’t have cared less about THAT possibility. Within a couple of days, my semen volume shrunk to practically nothing. Bad move on my part as she didn’t bother to mention the effects it could have on my sexual experiences. I was put on Finasteride by a FEMALE urologist.

Semen is simply the fluid in which the sperm travels, it’s not the sperm itself. John, I think you’re making semen synonymous with sperm. To John (the one who said what difference does it make if your semen volume shrinks since you’re probably at the age where you wouldn’t want to conceive a child), Journal of Clinical Endocrinology and Metabolism 2007 92:1659–65. The effect of 5-Alpha-Reductase Inhibition with Dutasteride and Finasteride on Semen Parameters and Serum Hormone in Healthy Men.

SOURCE: Amory JK, Wang C, Swerdloff RS, et al. You can always switch back to finasteride. You might experience a more noticeable drop in semen volume with one drug than another. Keep in mind, too, that even though these drugs are prescribed for the same condition, they work a bit differently. Keep in mind that these numbers are averages and not necessarily what one particular person will experience. Among the 73 participants who completed the trial, average semen volume dropped by 21.1% in men taking finasteride, and by 24% in those taking dutasteride over six months. But a randomized, placebo-controlled, head-to-head study of both drugs published in the Journal of Clinical Endocrinology and Metabolism in May 2007 yielded similar data. On average, their ejaculate volume decreased by 26%.īecause pharmaceutical companies conduct clinical trials under different conditions, we can’t compare their results. Avodart’s manufacturer also evaluated semen from 27 healthy volunteers who took that drug for a year. Other tests to evaluate semen in healthy male volunteers found a 22.1% median decrease in ejaculate volume. Following a four-year, placebo-controlled study of finasteride, the makers of Proscar noted that 3.7% of the 1,524 patients taking the drug reported decreased ejaculate volume in the first year fewer patients reported this problem in subsequent years. What you are experiencing is, I think, relatively common with both finasteride and dutasteride, although the drug manufacturers report that this side effect is uncommon. Marc Garnick, M.D., Editor in Chief of Harvard Medical School’s Annual Report on Prostate Diseases, says: After talking with my urologist, I recently started taking dutasteride (Avodart) instead. Although the drug reduced the size of my prostate, my body’s production of semen has diminished considerably. For the past several years, I used finasteride (Proscar) to treat my BPH.
