Microscopic testicular sperm extraction or Micro-TESE refers to a process that directly takes sperm from the testicular tissue of a man's reproductive system. The micro-TESE procedure aims to obtain the best quality sperm, get enough sperm to fertilize an egg from a woman and reduce damage to the reproductive organs.
Micro-TESE is considered for people who have abnormal sperm production due to previous testicular surgery, medical treatment, genetic problem and other male factor infertility issues.
Micro-TESE is conducted in the male patient under general anesthesia. A cut is made in the testis to search for the tubules containing sperms. Each testicle is examined under a high-power operating microscope. The surgeon searches for seminiferous tubules especially the swollen tubules which contain sperm. Later the testis is closed with very fine dissolvable sutures. The patient can go home after the procedure and should be able to do normal activities within 1 to 2 weeks.
If sperms are found during the procedure, they are extracted and used immediately to fertilize an egg or the sperm cells can be frozen, stored for future reproductive treatment using ICSI.
