If you are using topical Minoxidil or a combined Minoxidil-Finasteride product like Man Matters MinFin, and you are planning to start a family, it is natural to wonder whether these medications could interfere with pregnancy. In this article based on his educational video, Dr. John Watts -- dermatologist, trichologist and hair transplant surgeon in Hyderabad -- answers this question with reference to clinical evidence.
Can topical Finasteride enter the bloodstream?
"It is only the scalp that can absorb the topical application lotion. It will never get into the bloodstream and cannot affect the semen quality," says Dr. John Watts. In Man Matters' MinFin, the Finasteride concentration is only 0.1%. Even if trace amounts are absorbed, they are metabolised and excreted through bile and faeces before reaching the reproductive system.
What do studies on oral Finasteride show?
A Rhesus monkey study showed that with 1 mg oral Finasteride, only 7.6 nanograms per decilitre passed into the semen -- 750 times less than the effective dose that could impact semen quality. A Double Blind Randomized placebo-controlled human study found no significant change in sperm concentration, motility, morphology, or total sperm count with 1 mg oral Finasteride.
"At the most, what Finasteride does is control DHT but has no role to play in spermatogenesis -- the process of creation of sperm. The latter is the function dependent upon the testosterone hormone," explains Dr. John Watts.
One important caution: keep it away from your partner
Despite the safety profile for male users, Dr. Watts advises keeping Finasteride products away from female partners. Women who are pregnant or may become pregnant should not handle Finasteride products, as the drug can be absorbed through skin.
