IVF does not affect natural pregnancy. In vitro fertilization (IVF) is a process whereby eggs and sperm are combined outside the body, and then the fertilized eggs are cultured into embryos and transferred into the woman’s uterus, and the whole process does not affect the natural conception of the two parties in the future. Moreover, if the woman has been trying to conceive for many years due to blockage of one fallopian tube or tubal incompatibility, ovarian ovulation disorder, or abnormal sperm count, and has undergone IVF, and has given birth to a child, and is more relaxed mentally, and the ovarian ovulation returns to normal, and the peristaltic function of the fallopian tubes is normal, then the likelihood of getting pregnant naturally will be increased. If both men and women have diseases that affect fertility, it is recommended to actively treat them, keep a good mindset during the preparation period, develop good living habits, and actively prepare for pregnancy for 1 year, and if there is still no natural conception, IVF can be chosen.
