Wanting a pregnancy in the household is a clinician conversation, not a HairBase washout spreadsheet. Do not crush tablets if someone who can become pregnant may handle them.
Finasteride 1 mg for male pattern is a 5-alpha-reductase inhibitor. Labels and clinics discuss sexual side-effects in a minority; semen and fertility questions belong to urology or the prescriber, not a forum stack. This page will not invent a PMID that “1 mg causes infertility.” Related files cover long-term safety questions and PSA confounding — different URLs.
Do not double minoxidil as a fertility workaround. Do not start dutasteride from a TikTok “stronger DHT block.” Pregnancy pictograms on 5AR drugs are serious.
A partner who is pregnant and handled crushed tablets should call their clinician. Chest pain or acute urinary retention is care now. This is not medical advice.

Different labels and indications. Do not mash doses.
Can my partner take it?
People who can become pregnant must not take 5AR drugs or handle crushed tablets.
Same as sexual-side-effect page?
Related label family, different URL. This file is fertility/pregnancy handling, not a ranking of AE rates.
