Symptoms may also occur without regard to menstruation, these being the appearance of whitish flow in the nipples (without having any relation to breastfeeding) or pain during sexual intercourse. In men, the symptoms of infertility related to sperm can be the presence of semen of yellow or green tonality, red or brown spots; ejaculations very odorous, thick, watery or with little amount.

Frozen sperm is also useful in the case of men who are about to undergo chemotherapy or radiotherapy, because these treatments could jeopardize their future fertility.
