Pregnancy begins with the fertilization of the egg. The egg released from the ovaries is penetrated by a single sperm to cause fusion and the development of an embryo. In some cases, natural fertilization may not occur. In such cases, assisted reproductive techniques may be utilized to get pregnant. These includes:
Conventional In-vitro Fertilization (IVF).
Intra-Cytoplasmic Sperm Injection (ICSI).
Steps of ICSI:
A very fine delicate needle is carefully inserted through the zona (the shell of the egg) and into the centre (cytoplasm) of the egg.
The sperm is injected into the cytoplasm and the needle is removed.
The eggs are checked the next morning for evidence of normal fertilization.
Conventional IVF
You might have heard about Best IVF hospital in Delhi offering an effective technique to get pregnant. IVF Procedure in Delhi is simple yet complicated. It is based on the artificial interaction between eggs and sperms. In the laboratory, a set of egg cells will be put in a culture medium containing a suspension of your partner’s sperm. The fusion of both produces a fertilized egg which is then transferred to the uterus.
The procedure follows the natural course of interaction but in the laboratory. The concentration of the semen has to be modified to initiate the process. Hence, all semen samples cannot produce a fertilized egg with the IVF.
ICSI
ICSI is an advanced technique which prevents the limitations of IVF. Hence, ICSI is a much-favoured technique as compared to IVF. In this procedure, the sperms are individually selected and immobilized with the help of a micromanipulation station. A micromanipulation station includes a microscope, microinjectors, and micropipettes. The sperms are inserted into the egg with the help of a microinjector. Fertilization is monitored after a day of injection.
Who Needs ICSI?
Both IVF and ICSI are required for couples with infertility. ICSI is specifically recommended for couples with low sperm motility, low sperm concentration, a limited number of eggs, or previous failure with IVF.
