Preservation of Oocytes for Social and Medical Reasons

At Kamineni Fertility Center, we not only assist a couple in achieving a successful pregnancy but we also respect a woman’s desire to start a family when she is mentally ready.

The preservation of oocytes can be done through the first step of IVF, which is the ovarian stimulation, where the patient is administered with drugs to be able to retrieve more eggs than the normal cycle.

These eggs are retrieved and immediately put for freezing in liquid nitrogen.

The eggs can be frozen for a period of 5-10 years, without compromising on the quality of the eggs.

Semen Freezing

Semen or Sperm Freezing is an option available to men who are going through treatment that can affect their fertility like Cancer treatment, deteriorating sperm quality overtime or men who face difficulty in producing the sample on the day of the fertility treatment.

It can be used for only for Intra-cytoplasmic Sperm Injection. Semen freezing is also an option for donor sperms.

Embryo Freezing

  • Embryo Freezing is done once the embryos are formed for the process of the IVF or ICSI procedures.
  • Once the required number of embryos are transferred into the patient, they are put aside for Freezing, so that they can be used later when the couple either faces a failed IVF from the first cycle or wish to have another baby through the same method.
  • However, not all embryos survive freezing and thawing process, but it is not uncommon for the embryo to multiple and increase in number between the freezing and thawing process.

Embryo Transfer

  • Embryo Transfer takes place once the eggs have been fertilized and collected from the incubator the embryos transferred into the uterus for attaching itself to the endometrium.
  • Once the required amount of embryos are transferred, the remaining embryos are frozen, so that they can be used in the near future.
  • There are no or very few risks involved in this process.
  • Since the fertility diminishes with the age, the chances of achieving pregnancy with frozen embryos also decreases with age.
  • About 30-40 success rate with Women under 35.
  • Up to 25-30% for women between 35-40 years of age.
  • 15% for women between the age of 40-42.

Assisted Hatching

  • Before the embryo can attach itself to the wall of the womb, it needs to break out or ‘hatch’ from its outer layer called Zona Pellucida.
  • Our embryologists use acid, laser or mechanical methods to thin out the layer of the embryo in order to make it easier for the embryo to attach itself.
  • Since, only the outer protective layer of the embryo is being exposed to the treatment, the quality of the embryo is not affected.

Blastocyst transfer

Here, instead of transferring the embryo directly, it is allowed to develop further in the incubator as direct transfer of the blastocyst improves the chances of pregnancy with a single embryo transfer.

The procedure of blastocyst transfer is quite similar to that of the embryo transfer, except that instead of directly implanting, it is left to develop more and multiply in the cell count, then it is transferred into the uterus.
