IVF physical health depends on both sperm and eggs. IVF, also known as in vitro fertilization-embryo transfer, is a procedure in which the sperm and eggs of a couple who cannot conceive naturally are taken out of the body, combined outside the body and undergo early embryonic development, and then transferred to the mother’s uterus for development to give birth to babies, so it is said that the health of IVF depends on both the sperm and the eggs. If a couple is preparing for IVF, both partners should have a healthy lifestyle during this period, abstaining from alcohol and smoking, not staying up late and developing good habits. If the man’s sperm is healthy and energetic and the woman’s eggs are mature and of high quality, the embryo formed by the combination of the two will be of good and healthy quality.
