What is the difference between PICSI and ICSI?

PICSI, or Physiological ICSI, is a modified form of the ICSI procedure that may benefit a subset of patients who require ICSI. Men with poorer sperm samples often have a greater degree of immature sperm.

What is the success rate of ICSI?

Fertilization rates of 70 to 80 percent of all eggs injected – equivalent to fertilization with normal sperm – are currently being achieved, and pregnancy rates are comparable to those seen with IVF in couples with no male factor infertility.

Is PICSI better than ICSI?

Conclusion: There is no statistically significant difference between PICSI vs. ICSI, for any of the outcomes analyzed in this study. Enough information is still not available to prove the efficacy of the PICSI technique over ICSI in couples with male factor.

What is the average fertilization rate with ICSI?

Fertilization and pregnancy success rates with ICSI Fertilization rates for ICSI: Most IVF programs see that about 70-85% of eggs injected using ICSI become fertilized.

What is PICSI procedure?

Physiological intracytoplasmic sperm injection (PICSI) is a technique used to select sperm to use in Intracytoplasmic sperm injection (ICSI) treatment. It involves placing sperm with hyaluronic acid (HA), a natural compound found in the body.

What is PICSI sperm selection?

PICSI technique can identify mature spermatozoa from a sperm sample to select through HA (hyaluronic acid) receptors binding ability. Single centre analysis, prospective, randomized and triple-blinded trial were undertaken.

When is assisted hatching done in IVF?

third day
Assisted hatching is generally performed on the third day of embryo development. The embryologists use a laser to create a very small hole in the zona pellucida. Assisted hatching can also be done on previously frozen and thawed embryos.

Does the egg choose the best sperm?

Researchers from Stockholm University and the Manchester University NHS Foundation Trust found that the egg effectively chooses the sperm it wants, and rejects the others. “Human eggs release chemicals called chemoattractants that attract sperm to unfertilised eggs.

Does assisted hatching speed up implantation?

Conclusion: Assisted hatching may enhance embryo implantation not only by mechanically facilitating the hatching process but also by allowing earlier embryo-endometrium contact.
