1. Does having an orgasm help you to get pregnant?
In theory, an orgasm could help you get pregnant, but experts agree it’s definitely not necessary. During an orgasm, the uterus contracts, causing a vacuum effect which could theoretically move sperm up into the uterus. But Sandra Gahn, co-author of The Infertility Companion: Hope and Help for Couples Facing Infertility points out, “There’s a certain logic in this theory, yet while studies have shown such a vacuum effect exists, whether it actually brings about a higher pregnancy rate is unproven.”
The key to getting pregnant is not having an orgasm (although it sure makes trying more fun), but timing intercourse to correspond with your fertile period. Trying to force yourself to have an orgasm every time is a recipe for disaster since the stress will not put you in the mood. If you do want to have an orgasm during intercourse, many women are not able to have an orgasm from intercourse alone, so added manual stimulation may help.
