There are two types of azoospermia: In the case of azoospermia, the probability of obtaining usable sperm is low, and the possibility of using donor sperm may need to be considered. Other researchers believe that the incidence of these birth defects occurring is similar to those found in natural pregnancy, and therefore should not be a deterrent in using them. If sperm cannot be collected by via masturbation, they can be surgically removed intrracitoplasmatica a testicle through a small incision.
Experts recommend that men with little or no sperm in their semen not due to a blockage have genetic testing before they start ICSI. To prepare for a procedure using your own eggs, you must get daily shots and be closely monitored for 2 weeks before the eggs are collected.
ICSI, Intracytoplasmic sperm injection
These mature eggs are collected 34 to 36 hours later. A glass tool is used to hold an egg in place then a tiny glass tube is used to put one sperm directly into the egg.
After allowing time for development culturing in the lab overnight, eggs are checked to see if they have been fertilized. After this incubation period, the eggs that have been successfully fertilized and have had 3 to 5 days to further develop further are selected.
Your doctor will recommend how many embryos to transfer, based on your inyecxion and other information about inyedcion. The other embryos may be frozen for future use. Some of the injections can be rather painful.

All of these procedures are done on an outpatient basis and they only require a short recovery time. Your doctor may also advise you to avoid strenuous activities for the rest of the day.
Used as part of an In Vitro Fertilization treatment cycle and provided that the eggs are of good quality, ICSI is often successful for men who have impaired or no sperm in their ejaculate. Please discuss these risks with your doctor. A woman over age 35 to maximize her chances of conceiving with her own eggs and having a healthy pregnancy, she may choose to have more embryos transferred than a younger woman would.
But this increases her risk of having multiple pregnancy.
Because of the risks to the babies of multiple pregnancy, many experts recommend that you limit the number of embryos transferred. Your doctor will recommend a certain number of embryos based on your age and other factors such as general health and fitness. Women over 40 have a high rate of embryo loss when they use their inyecccion eggs.
Donor eggs may work better these women.

ICSI is an effective treatment for sperm-related infertility but it may have genetic risks. People who have a chromosomal problem can seek genetic counselling to learn about their chance of having a child with birth defects.
If you and your doctor are concerned about the possibility of passing on a genetic disorder to your childtalk to your doctor about testing the embryo before it is transferred to the mother.
