What is TESE / PESA
A Percutaneous Epididymal Sperm Aspiration (PESA) and Testicular Sperm Aspiration (TESA) are surgical procedures that are used (typically in conjunction with IVF) to find and extract sperm from the male partner who does not have sperm in his semen/ejaculate
In some individuals, spermatozoa may not be present in the ejaculate. This condition is called Azoospermia. This can be either due to problems in sperm production itself or due to obstruction to the flow of semen during ejaculation. Reproductive tract obstruction can be acquired - as a result of infection, trauma, iatrogenic injury which can occur during bladder neck, pelvic, abdominal or inguino-scrotal surgery.
Two Techniques of Sperm Retrieval:
Epididymal sperm retrieval & micromanipulation have revolutionized treatment of male infertility in the past decade. Men with congenital bilateral absence of the vas defences (CBAVD) or reproductive tract obstruction are now able to achieve pregnancies with use of these advanced techniques.
