What is Intracytoplasmic sperm injection (ICSI) fertility treatment
There could be multiple reasons for infertility. Sometimes a simple IVF (in-vitro fertilization) procedure can be your answer to infertility. ICSI (intracytoplasmic sperm injection) is a simple procedure done with IVF to ensure the fertilization of the egg, typically used in cases of severe male infertility. In this article, we shall cover everything you need to know about ICSI including: 1) What is ICSI treatment? 2) How does ICSI work? 3) Why need ICSI? 4) Success rate 5) Cost of ICSI treatment in India 6) Risk factors involved in ICSI
What is ICSI treatment?
To fertilize a woman's egg, the head of the sperm must attach to the outside of the egg firstly. Once attached, the sperm pushes through the outer layer to the inside of the egg (cytoplasm), where fertilization takes place. Sometimes, for a variety of reasons like the thickness of the egg’s outer layer or the inability of the sperm to swim, the sperm cannot penetrate the outer layer. In such cases, a procedure called intracytoplasmic sperm injection (ICSI) can be done along with in vitro fertilization (IVF) to help fertilize the egg.How does ICSI work?
Doctors perform the ICSI procedure with IVF, which involves the injection of a single sperm directly into the cytoplasm of the egg. During this procedure, the doctor inserts a tiny needle, called a micropipette (holding a single sperm) into the center of the egg. If the eggs are fertilized, they are left to mature for several days, at which point they become multicellular embryos. Healthy embryos are used by doctors for the embryo transfer procedure (inserting an embryo into a woman’s uterus).Why need ICSI?
ICSI can help couples who have struggled with infertility, especially when infertility issues are male-related. ICSI during IVF gives you an enhanced fertilization rate, which can increase the number of fertilized eggs available for transfer or freezing. ICSI helps to overcome fertility problems, such as:- Men with severely low sperm count
- The sperm may not move in a normal fashion
- Men with problems associated with sperm development
- Men with a blockage that prevents sperm from being ejaculated (such as a vasectomy)
- The male partner produces too few sperm to do artificial insemination (intrauterine insemination [IUI]) or IVF
- The sperm may have trouble attaching to the egg
- Eggs have not fertilized by traditional IVF, regardless of the condition of the sperm
- In vitro matured eggs are being used
- Previously frozen eggs are being used
Success rate
ICSI fertilizes 50% to 80% of eggs. You might assume all eggs get fertilized with ICSI-IVF, but they don’t. Your Fertilization isn’t guaranteed even when a sperm is injected into the egg. The following problems may occur during or after the ICSI process:- Some or all of the eggs may be damaged
- The egg might not grow into an embryo even after it is injected with sperm
- The embryo may stop growing
