IMSI / TESA / PESA
IMSI
Intracytoplasmic morphologically selected sperm injection (IMSI) examines the sperm and selects healthy ones using high-magnification digital imaging microscope.
IMSI involves the following steps:-
1. Selections of sperms: The collected sample is examined under a microscope 15 times stronger than the normal microscope to collect the first set of sperm
2. Discading abnormal sperm: After examining under the microscope, sperms with abnormalities are discarded.
3. ICSI: Then the sperms are inserted into the female partner’s vagina using a catheter through the cervix. ICSI is done if any assistance is required for the fertilization to happen.
Pesa
Percutaneous Epididymal Sperm Aspiration
Pesa treatment involves needle biopsy, where the needle is directly placed into the epididymis.
Tesa
Testicular Sperm Aspiration
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.
Sometimes men produce semen but lack necessary sperm count for fertilization to happen.
With the help of medical techniques like TESA/PESA sperm is retrieved surgically and then IVF treatment is done. The best method is chosen after conducting few tests
