PICSI: Purpose, Procedure & Results
What is Physiological Intra-Cytoplasmic Sperm Injection (PICSI)?
A good technology plays an important role in completing families who have long awaited the arrival of a new member. PICSI is one such advanced treatment option. This treatment has proved widely successful in improving the success rate of IVF.
When to opt for PICSI?
- High DNA fragmentation index in the spermatozoa: Damage to the DNA carried by the sperm.
- When repeated attempts for achieving fertilization through ICSI fail.
What is the Procedure for Successful PICSI?
Normally, millions of spermatozoa are deposited in the upper vagina. Out of these, only 10% are able to travel up to the cervix. Further, only 0.5% of these spermatozoa reach the fallopian tube and only a single spermatozoon is able to fertilize the oocyte. This is possible if and only with spermatozoa having normal physiology. Hence, when selecting the spermatozoa for IVF, those with normal physiology are selected for injecting the oocyte extracted from developed follicles.
PICSI has a higher success rate in developing good quality embryos resulting in good changes of implantation and pregnancy.
