Fertility is the ability to conceive and produce offspring. Infertility is the inability to conceive after a year of unprotected intercourse. Infertility can affect men and women of all ages.
In vitro fertilization (IVF) is a procedure in which an egg is removed from a woman and fertilized by a sperm outside the body. The fertilized egg is transferred to the uterus to establish a pregnancy. Different sperm harvesting procedures can be used to obtain sperm and they include:
Testicular Sperm Aspiration (TESA) – It is a procedure performed under local anesthesia where in a needle is inserted into the testicle and sperms are aspirated.
Percutaneous Sperm Aspiration (PESA)-This technique involves aspiration of sperm using a small needle and is coordinated with egg retrieval.
Testicular Sperm Extraction (TESE) – In this method small sample of testicular tissue will be collected through a small incision in the testis.
Microdissection TESE- It is an advanced version of TESE that involves removal of minimal testicular tissue with maximum sperm yield.
