Reproductive science has evolved to the point where the cause of infertility is still undetected in 20% of all infertility cases. Not the least of these is the neglected factor of the sexual act itself. It is a self-evident fact that sex is the lubricant of intimacy, and couples with harmonious sex life tend to have good relationship and high frequency of sex, and of course high conception rate with long-term high quality and regular sex life. Most of the couples preparing for pregnancy know that they can have intercourse during ovulation in order to conceive a baby, and they have heard many claims of sexual positions to help conception (the science of which is debatable), but most people do not know that women having orgasm during sex helps a lot in conception. This muscle contraction accelerates the peristaltic movement of the fallopian tubes, which improves the function of the umbilical end of the tubes to catch the eggs, and only when the tubes catch the eggs from the ovaries into the pelvis can they meet the sperm. The increase in peristalsis of the fallopian tubes during female orgasm does not only act on the umbilical end, it is an overall increase in peristalsis. Because the sperm and egg meet in the abdomen of the fallopian tube to be fertilized and then return to the uterus to be laid, it is very important that the tubes are open. The inside of the fallopian tubes are not smooth, but have many, many villi, so a soft and peristaltic tube will facilitate the movement of the fertilized egg. This is the second aspect of the female orgasm that helps with fertility. When women have orgasm, pelvic congestion is obvious, blood flow is accelerated, the uterus is rich in blood flow, and the endometrial tolerance increases, which is conducive to the fertilization of the egg, and this has been proven by the research of our fertility experts. Let reproduction become a natural result of sexual pleasure after a bar, it is the sweetest thing!
