What is the difference between IVF and Microinjection?

What is IVF?

In-vitro-Fertilization (IVF) is a common infertility treatment. IVF is a procedure, used to overcome a range of fertility issues, by which an egg and sperm are joined together outside the body, in a specialized laboratory. During the procedure, a fertility doctor takes the eggs from the ovaries using a small needle and fertilizes them with sperm in a specialized lab. After fertilization happens, the eggs develop into embryos. Three to five days later, the specialist re-implants the embryos back into the uterus.

What are the reasons for using IVF?

  • low sperm count
  • problems with ovulation due to conditions like polycystic ovary syndrome
  • problems with the fallopian tubes
  • endometriosis
  • A wish to avoid passing on inherited genetic disorders to your children.

Who may not benefit from IVF?

If ovaries do not produce healthy eggs, and you are not interested in getting a donor, you may have to explore other options outside of IVF.  Also, if you are over the age of 37, it is more difficult to get pregnant with IVF.  Donor eggs are a great alternative for women approaching 40 who want to increase their chances of pregnancy. About half of all women that attempt IVF with donor eggs are successful.

What is the success rate in the IVF treatments?

The partners should be informed about the issues that may affect the success because many criteria such as the age and socioeconomic facilities of the partners, the equipment at the center, the experience of the team members, and other disorders of the body will be effective. The partners who want to have a baby should meet with the gynecologists for infertility treatment without waiting for long. There will be a negative success rate increasing with the age later on. Therefore, the age is one of the mostly discussed issues in the IVF treatment.

The success rates with the age for IVF treatments

  • If the woman who wants to get pregnant is under 35, then the chance of success will be around 45-50%;
  • If the woman is between 35 and 38 ages, then the rate will get lower down to around 40%;
  • If the woman is between 38 and 40 ages, then the success rate will be limited to 30-35%, and
  • If the woman is 40 and above, then unfortunately the rate will remain at the level of 10-20%.

The difference between IVF and Microinjection

Intracytoplasmic sperm injection (ICSI) is very similar to conventional IVF in that gametes (eggs and sperm) are collected from each partner. The difference between the two procedures is the method of achieving fertilization. ICSI refers to the laboratory procedure where a single sperm is picked up with a fine glass needle and is injected directly into each egg. This is carried out in the laboratory by experienced embryologists using equipment. Very few sperm are required and the ability of the sperm to penetrate the egg is no longer important as this has been assisted by the ICSI technique. In IVF procedure, the germ cells received are allowed to wait together for fertilization. Otherwise, the sperm is injected into the egg cell and the fertilization is implemented (microinjection).
