This is an effective method with the highest pregnancy rates and minimal discomfort for a man and the least pain. The sperm is retrieved from their testicle or epididymis by biopsy. Then the sperm is transferred into the woman’s eggs. An important note: the procedure is performed microsurgically.
Ejaculate in some men lacks the sperm. In this case, many reproductive technologies, including IVF and ICSI, require some additional measures. The main aim of preparation procedures is to get the adequate amount of sperm. The following methods are used:
- TSE - testicular sperm extraction;
- MESA - microsurgical epididymal sperm aspiration;
- PESA - percutaneous epididymal sperm aspiration.
MESA allows obtaining the necessary amount of sperm of high quality. This is the most effective method and the safest as well. The risk of complications is very low. This is very important because treatment of male infertility must be not only effective but also safe.
Using any of these methods, doctors do their best to obtain the material of good quality for further freezing and using in the next cycles, in case IVF attempt fails.
Azoospermia is a medical condition of a man whose semen contains no sperm. The development of this condition can be explained by several factors. Azoospermia is classified into two types.
- Obstructive azoospermia. It refers to no sperm in a man’s semen as a result of blocked spermatic ducts and the sperm can not be delivered. Blocked spermatic duct ducts can be a congenital pathology or a complication of vasectomy. In this case, the sperm is of good quality but it should be retrieved using certain manipulations. Most often PESA is used when a fine needle is inserted into the epididymis to collect the sperm. An alternative procedure is TSE with biopsy. Both procedures are performed in the clinic with local anesthesia. If in obstructive azoospermia, there is spermatogenesis then success rate of TSE is 100%.
- Non-obstructive azoospermia is a pathology is associated with critically low number of sperm in the semen. Biopsy is performed to identify small areas in the testicle where sperm is produced. This procedure is call TSE. Today a new procedure is used to treat male infertility – microTES. Special surgical microscopes are used and the area with spermatogenesis can be identified very accurately. One more option is testicular mapping allowing to collect up to 70% of the sperm for fertilization.
After the above mentioned methods we typically recommend ICSI/IMSI to increase success rates of fertilization.
