IVF and ICSI differ in the way the eggs and sperm are fertilized. IVF and ICSI require the collection of eggs and sperm. Controlled fertilization occurs in a laboratory dish. And the embryos are kept in an incubator for 3-5 days.
What is IVF?
IVF or In Vitro Fertilization or what is known as Test Tube Fertilization is an Assisted Reproductive Technology (ART). Which involves taking sperm and eggs and fertilizing them in a lab. เล่นเกมคาสิโน UFABET ทันสมัย ฝากถอนง่าย The embryologist will place several sperm and one egg in a dish and let the sperm swim and compete to penetrate the egg similar to the natural method. Fertilization usually occurs within one night. The embryos are then kept in an incubator for 3-5 days. With the best quality embryos selected and transferred back into the uterus.
What is ICSI?
ICSI or Intra-Cytoplasmic Sperm Injection, commonly known as ICSI, is the injection of sperm into an egg, instead of letting the sperm naturally penetrate the egg. It is a method of in vitro fertilization (IVF) and a treatment for male infertility.
How are IVF and ICSI similar or different?
In both IVF and ICSI, eggs and sperm are collected, fertilization takes place in a dish, and the embryos are kept in an incubator for three to five days before being transferred to the uterus for implantation and pregnancy. The difference is that in IVF, the sperm penetrates the egg itself, whereas in ICSI, a scientist in the embryo lab injects the sperm directly into the egg.
What are the benefits of ICSI?
ICSI is a treatment for male infertility. It is usually done when sperm cannot penetrate and fertilize the egg due to the following factors:
- Low sperm count
- No sperm was found in semen, but sperm was collected from the epididymis or testicles.
- Sperm has abnormalities, such as abnormal shape or poor motility, at a high rate.
- High anti-sperm immunity
In those who use frozen eggs or sperm, or eggs from women over 35 years of age, or who have had a low fertilization rate from traditional IVF, doctors may also recommend ICSI. 60% of IVF treatments include ICSI, and the success rate of ICSI is around 50% – 80%.
