Frozen Sperm

Sperm freezing or technically sperm cryopreservation is the process of collecting and freezing sperm in liquid nitrogen for some future use. Some of the common reasons associated with freezing sperm include – possible cancer treatments, occupational hazards, career & lifestyle choices, and in most cases, it is for fertility treatment in-absentia.

Sperm Extraction and Retrieval Procedure: PESA | TESA | TESE
What is a PESA TESA TESE?

TESA, TESE and PESA are forms of male fertility treatments that include recovery of sperms through the minor medical surgical process. These are different types of sperm retrieval including – Percutaneous Epididymal Sperm Aspiration (PESA), Testicular Sperm Aspiration (TESA), Testicular Sperm Extraction (TESE).

PESA involves the use of needle and syringe technique as for a needle biopsy, while TESA Treatment is similar to a needle biopsy but involves placing a needle attached to a syringe through the skin of the scrotum, and simply sucking out the fluid from the testicle. In case of TESE the testicle is surgically opened to extract a larger sample of tissue and retrieve the sperm.

Why does it work?
These procedures work primarily because of the fundamental cause of male infertility, which is not the absence or low quality of sperm but that there is a challenge with the delivery mechanism of the same. This could be caused by blockages, or any other anatomical challenges which make it difficult for the sperm to reach the uterine cavity for fertilization.

What is the process?

The process of sperm extraction and implantation involves three steps – evaluation, extraction, and implantation. The evaluation is to determine the cause of the infertility and arrive at the appropriate procedure for extraction of the sperm. Extraction involves the actual retrieval of the sperm, while insemination takes place either via the IUI or IVF modes.
