Generation IVF is mainly for infertile women, the requirements for women are relatively low, the requirements for male sperm are higher, there are certain requirements for sperm count, vitality, deformity rate, etc., which need to be met in order to do generation IVF. The spermatozoa for fertilization should have a normal shape. Normal spermatozoa morphology is like a tadpole, which is mainly composed of three parts: head, body, and tail, with a slightly flattened head, ovoid shape, and a regular and clear outline. The density of sperm should be more than 20 million per milliliter, if the density of sperm is too small, then the sperm survival rate will be reduced, which will lead to fertilization failure. Generation IVF usually involves selecting the most viable and healthy sperm from a large number of sperm with over 60% sperm viability as the union of the fertilized egg. Men are advised to check their sperm motility before undergoing IVF to see if it meets the requirements, and to pay attention to their daily routine and diet to ensure sperm motility.
