PROCEDURES FOR SPERM HARVESTING AND RETRIEVAL – TESA AND TESE
HOW IS MALE INFERTILITY TREATED?
Some male infertility conditions can be treated with medications and hormone therapy or micro-surgical procedures. Other conditions may require advanced male fertility treatments to harvest and retrieve sperm. The procedures Dr. Robert Pugach utilizes are:
- TESA – TESTICULAR SPERM ASPIRATION
- TESE – TESTICULAR SPERM EXTRACTION
TESE is done for men who typically have no sperm in their ejaculate and an underlying condition such as Sertoli Only syndrome where sperm can be made but have no way of getting out of the Sertoli cells in the testicles. It is timed to egg retrieval in a female partner but some sperm may also be frozen.
PESA – PERCUTANEOUS SPERM ASPIRATION
Testicular sperm aspiration can be done by placing a needle into testicular tissue and withdrawing viable sperm. It is appropriate for men with obstruction of the vas deferens where couples want in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI).
MESA – MICROSURGICAL EPIDIDYMAL SPERM ASPIRATION
This is the procedure typically performed for men with obstruction of the epididymis or vas deferens, situations that occur after a vasectomy or in men with congenital absence of the vas deferens.
