TESA – TESE ICSI
TESA – TESE ICSI is a process in which testicular sperm extraction is used to have sperm directly from the testes when is absent from the semen.
When TESA – TESE ICSI is necessary
- Sperm production in the semen is inadequate in the testes.
- There is an obstruction stopping the sperm from exiting the penis.
Testicular tissue samples are removed and sent to a sperm bank. In the event that sperm is found in the tissue sample, it will be preserved and frozen. Men may choose to freeze their sperm prior to receiving cancer treatment, or they may choose to attempt biological children following cancer treatment.
The process of testicular sperm aspiration (TESA) involves puncturing the testis with a needle and aspirating tissue without applying any pressure. Percutaneous epididymal sperm aspiration (PESA) involves aspirating fluid directly from the head of the epididymis using a tiny needle. These retrieved sperm cells are used in reproductive therapies such as Intracytoplasmic Sperm Injection (ICSI) and do not necessitate a surgical incision.
Why the procedure is useful
Intracytoplasmic sperm injection (ICSI), a particular kind of IVF, is utilized in conjunction with the quantity of sperm discovered using PESA or TESA.
Before beginning any fertility treatments, the testicular sperm extraction (TESE) procedure is performed to ensure that sperm production is occurring. Once this is confirmed, the procedure is repeated the day of egg retrieval, using the fresh sample for intracytoplasmic sperm injection (ICSI).
Sometimes, if there are sufficient viable cells, the sample might be frozen for use in upcoming treatment cycles. After the fertilized eggs are cultivated in our lab for a few days, a healthy embryo is inserted into the uterus.
