Eating sperm by a woman affected her or not? i heard somewhere eating sperm is good for girls.

Sperm: Neither good nor bad. ( i'm fairly sure that a male made that one up).

Sperm ingestion: There is a study that suggests possible health benefits from ingesting semen. It proported a reduced risk of breast cancer if a woman engages in fellatio at least three times a week. Two other benefits from semen that have been suggested (but do not involve ingestion per se) include an antidepressant effect on women and possible reduction of pre-eclampsia. See below.
