Injection of sperm into the soy sauce cell of the ovule (ICSI): Solution for infertile couples due to male factors

The article was consulted professionally by Master, Dr. Nguyen Thi Cam Van – IVF Lab Doctor – Center for Assisted Reproduction – Share99 Times City International Health Hub. The doctor has experience and strengths in performing intensive techniques on assisted reproduction in the in vi test tube fertilization lab.

Normally, eggs are fertilized when sperm moves into the egg, however, in case the sperm cannot penetrate inside the egg due to the thick outer layer of the egg or weak sperm leads to male infertility. In this case, the doctor will perform the technique of injecting sperm into the egg-like cell to help the sperm complete the fertilization process.

1. What is the injection of sperm into the soy sauce cell of the ovule?

Intracytoplasmic sperm injection (ICSI) is performed at assisted reproduction centers by injecting a healthy sperm directly into the egg to create the embryo. This technique is performed to help fertilize infertile couples due to men's poor sperm quality, deformed sperm or even no sperm in semen or couples who have failed several times in in vismable in vism (IVF) fertilization before. This technique has brought much success to couples who rarely desire to have children.

The ICSI technique is performed similarly to IVF, starting with the fact that the woman will use the drug to stimulate the ovaries in order to increase the number of eggs. After that, these eggs will be sucked through the vaginal line under the guidance of an ultrasound machine and the eggs will be cultured under appropriate conditions at the in viinal fertilization lab. After taking semen samples from the husband, the sample will be filtered to choose good mobile sperm, good erm. Then, using a modern micro-injection system, a sperm with a good edging and mobility will be caught with a glass needle and injected directly into the egg.

After injecting sperm into the egg future cell, the egg will be further cultured in the in vi vismable insevenous lab and assessed for daily development. When the embryo is created, the good quality embryo will be transferred back to the mother's uterus. After that, the doctor and the spouse will monitor the symptoms of pregnancy, when there are symptoms, the doctor will use a blood test or ultrasound to determine if the mother is pregnant or not.

2. When to inject sperm into the soy sauce cell of the ovule?

Your doctor may prescribe ICSI if:

  • Men with very small sperm numbers
  • Sperm of abnormal or less mobile shape
  • the couple had performed IVF before but had no or very few fertilized eggs.
  • The husband does not have sperm in the semen that needs to be collected surgically from obtaining sperm from the testicles or the crest of the testicles. For example, the husband has a vasecti vasectitis or has an obstruction that prevents sperm from ingesting due to illness, injury or heredity or because the husband has too few sperm numbers.
  • The husband performed sperm storage before carrying out treatment for diseases that adversely affect the quality of sperm, for example cancer treatment. However, the quality of sperm stored is not high, especially if the sperm is stored due to the fertility of the husband who is threatened.
  • Eggs defrosted from egg freezing cycles

3. Success rate of injection of sperm into the carcinum of the ovule

The ICSI technique can perform fertilization for 50% to 80% of eggs. But some problems may occur during or after the implementation of ICSI such as:

  • Some or all eggs may be damaged.
  • Eggs may not develop into embryos even after being injected with sperm.
  • The embryo may stop growing.

4. Can ICSI affect your baby's development?

Normally, when a woman is pregnant by natural methods, there is a 1.5% to 3% chance that the fetus has birth defects. The likelihood of a fetus having a birth defect when performing IVF-like ICSI is not higher than for natural conception.
