Sperm Retrieval Techniques

Sperm retrieval or sperm harvesting refers to procedures in which sperm is retrieved directly from the testes or the epididymis which is the tube that carries the sperm from the testes to the vas deferens. It is indicated in men that have no sperm or low sperm count on semen analysis. Sperm retrieval techniques have greatly improved the chances of conception for male factor infertility. Sperm can be retrieved from either the epididymis which is the duct that carries the sperm from the testes to the vas deferens or directly from the testes. Epididymal sperm retrieval techniques are - PESA - Percutaneous epididymal sperm aspiration MESA - Microscopic epididymal sperm aspiration Testicular sperm extraction techniques are - Testicular sperm extraction (TESE) - In this a small amount of testicular tissue is removed and this can then be used for IVF. Microsurgical sperm extraction (MicroTESE) - In this an operating microscope to find pockets of sperm production within the testes and extract sperm from the healthiest tubules. Depending on the IVF program, sperm that is harvested is used fresh by timing it with the partner’s egg retrieval or is frozen for later use. #spermretrieval #PESA #MESA #TESE #microTESE #malefactorinfertility #azoospermia #IVF #fertility #infertility #reproductivehealth #womanshealth #fertilihealth #vasectomyreversal #patienteducation #ICSI #frozensperm #donorsperm
