TESA or testicular sperm aspiration is the newest sperm retrieval method. This treatment is prescribed to men with azoospermia, a condition in which an absence of sperm is found in their ejaculate. In the past, the main choices to treat azoospermia were reconstructive surgery or donor insemination. Presently, the advent of intra-cytoplasmic sperm injection (ICSI) has made numerous azoospermia men become biological fathers utilizing sperm obtained from their epididymis or testis.
When Is TESA Recommended?
Sperm retrieval is performed when pregnancy is the objective yet not possible without assistance. It is for men who have practically no sperm in the semen or men who are not able to ejaculate. In these cases, sperm can be collected from different parts of the reproductive tract. For good pregnancy rates, sperm retrieval is utilized with in vitro fertilization (IVF) and intracytoplasmic sperm injection(ICSI).
In vitro preparation (IVF) is the process to combine an egg and sperm in a lab dish for fertilization. This combined sperm and egg are known as embryos. The embryo is moved to the uterus for development.
Intracytoplasmic sperm injection (ICSI) is an IVF process where a single sperm can be injected directly into an egg.
How is TESA performed?
TESA procedure in Mahabubnagar is performed by placing a needle into the testis and aspirating fluid and tissue utilizing negative pressure. The sample can be processed to extricate the sperm cells in the embryology lab utilizing the ICSI or intracytoplasmic sperm injection.
The sperm cells need not be matured and pass through the epididymis to fertilize an egg. Since the testicular sperm is immature, they need ICSI, a strategy in which a single sperm is taken from the semen and injected directly into the egg.
TESA can give some discomfort for a few days as it’s a marginally mind-boggling procedure. It is done under local anesthesia or sedation as per the patient’s inclination in daycare no need for any hospital stay. If tesa doesn’t provide enough sperm, testicular biopsy is needed in such cases.
