Side effects of monoxide hair regrowth treatment?

Minoxidil has not been shown to negatively impact males fertility. I suggest seeing a hair loss expert to evaluate and go over your condition and provide you information about your best treatment options. There are great non-invasive options like PRP/progesterone and/or hair transplantation. See an expert. Best, Dr. Emer

Topical minoxidil is a medication used for hair loss.  It is not known to not cause fertility problem in men.  If you are concerned it is best to discuss medication and its side effects with your doctor.

The most common side effect of Minoxidil is local irritation of the scalp.Other side effects are ocassional fluttering of the pulse (palpitations), and increase in facial hair in women.Minoxidil should have no effect on sperm or fertility-you may be thinking of Propecia(Finasteride).

No.  Unlike this popular hair-loss drug, another drug, Finasteride is associated with a variety of side-effects on male reproduction primarily affecting libido and should not be touched by women or children but no warnings about Minoxidil have been issued to my knowledge. 60 days is not enough of a trial to determine if it works or not. You need to take Minoxidil for 3-4 months to find out. It does have side effects such as lower blood pressure and is irritating to the skin for some folks.

Topical
minoxidil should not impact male fertility.
