It is not necessary for women to have an orgasm to conceive, but it is possible to conceive without an orgasm, but having an orgasm can increase the chances of conception because: ① Experimental studies have found that the pressure in the uterus is positive during orgasm and drops sharply to negative after orgasm, thus creating the effect of sperm inhalation by the uterus; ② During sexual arousal, the inner 2/3 of the vagina is spherically enlarged and the outer 1/3 is constricted due to the contraction of blood vessels and the muscles surrounding it. (3) The normal vaginal environment is acidic, which is not conducive to sperm survival and activity, but during orgasm, the leakage of fluid from the vaginal wall vessels increases and tends to be alkaline, which is conducive to sperm activity. Therefore, stop ignoring your body’s call, put down your mind baggage, actively engage in sex, and maybe the crystallization of love will come at that moment!
