For women:
Blends™ treatments, both topicals and capsules, should be avoided if pregnant, trying to get pregnant, or breastfeeding.
For men:
Many men will go off finasteride or dutasteride containing pills and compounds while trying to conceive, as there is some thought that while taking the pills its decreases sperm count and/or motility. This effect is temporary only while taking such medications, so most men who take a holiday from the pills, will resume after conception.
