Hormone disorders, illness, reproductive anatomy trauma and obstruction, and sexual dysfunction can affect sperm and prevent conception. The longer men go without treatment, the longer they’re likely to be the problem. In some male patients it’s irreversible; however, some may be caused by a treatable medical condition.
The development of sperm takes place in the ducts of the testes. As the cells divide, they produce mature sperm cells. It takes about 16 days to complete a cycle of six stages and mature sperm is only produced after five cycles. It’s the endocrine system that controls sperm development. This is a delicate process because sperm needs two months to develop, and if there is illness during the first cycle, the sperm may not grow to maturity. Even if the male is in good health at the time, he is examined for the IVF procedure, the damage might have occurred earlier.
If the cause for the infertility has been successfully diagnosed, the male role in IVF is the next step.
First of all, the sperm will be mixed with the eggs in the Petri dish. If the procedure is in vivo, the sperm and egg will be deposited in one of her fallopian tubes or in her uterus. Ifit’s determined that your sperm is causing the infertility, it may be necessary to go to donor sperm.
After the female partner has been prepared with a round of infertility drugs and it is determined that she is producing eggs that are ready to be fertilized, then you will supply the sperm, which will also undergo preparation by the removal of inactive cells and seminal fluid. The semen may also be collected ahead of time and frozen and then thawed at the proper time. Sperm and egg(s) will be incubated together for about 18 hours when it is assumed that the egg is fertilized. It should show two pronuclei—hers and his. These will later fuse to become a single nucleus. When the doctor sees the two pronuclei, he is very happy because it’s an indication that a successful fertilization has occurred.
After a few days, the embryo will be implanted in the uterus and will hopefully thrive and grow there into a healthy baby.
