Cryopreservation for IVF

In vitro fertilization (IVF) is a process in which eggs are fertilized by sperm outside the body, in a laboratory setting. Cryopreservation is often used in the IVF process to preserve embryos, eggs, and sperm for future use.

In this article, Dr. Hrishikesh Pai from Babies & Us IVF and ICSI Centre, one of the best IVF centres in Mumbai will be talking about the different types of Cryopreservation for IVF.

We’ll see the types of IVF cryopreservation below,

Embryo Cryopreservation

Embryo cryopreservation is the process of freezing embryos for future use in pregnancy. Embryos can be frozen at various stages of development, but are typically frozen at the blastocyst stage, which is 5-7 days after fertilization.

Cryopreservation is often used in the context of in vitro fertilization (IVF), where couples may have embryos created and then frozen for future use if the initial IVF cycle is not successful or if the couple wishes to delay pregnancy. Embryo cryopreservation can also be used by couples who wish to preserve their fertility for personal or medical reasons.

To cryopreserve an embryo, it is first placed in a special freezing solution to protect it from damage during the freezing process. The embryo is then placed in a cryoprotectant solution, which helps to further protect the cells from damage during freezing. The embryo is then placed in a cryovial and placed in a controlled rate freezer, where it is slowly cooled to a temperature of -196°C or -320°F. The frozen embryo is then stored in a tank of liquid nitrogen until it is needed for transfer to a woman’s uterus.

Embryo cryopreservation has been shown to be a safe and effective method for preserving embryos for future use in pregnancy. However, the success rate of pregnancy using cryopreserved embryos can vary and may be lower than the success rate of fresh embryos.

Egg Cryopreservation

Egg cryopreservation is the process of freezing unfertilized eggs for future use in fertility treatments, such as in vitro fertilization (IVF). It is also sometimes called oocyte cryopreservation. To know more about cryopreservation ask the doctors by clicking here.

Dr. Hrishikesh Pai from Babies & Us Fertility IVF & ICSI Center, best IVF centre in Mumbai saysEgg cryopreservation can be useful for women who wish to preserve their fertility for personal or medical reasons, such as career or family planning, or for women who are facing medical treatments (such as chemotherapy or radiation) that could potentially harm their fertility. It can also be used by couples who wish to use donor eggs in the IVF process.

To cryopreserve eggs, they are first removed from the ovaries through a surgical procedure called ovarian stimulation and retrieval. The eggs are then placed in a special freezing solution to protect them from damage during the freezing process. They are then placed in a cryoprotectant solution, which helps to further protect the cells from damage during freezing. The eggs are then placed in a cryovial and placed in a controlled rate freezer, where they are slowly cooled to a temperature of -196°C or -320°F. The frozen eggs are then stored in a tank of liquid nitrogen until they are needed for fertilization.

Sperm Cryopreservation

Sperm cryopreservation is the process of freezing sperm for future use in fertility treatments, such as in vitro fertilization (IVF). It is also sometimes called semen cryopreservation.

Sperm cryopreservation can be useful for men who wish to preserve their fertility for personal or medical reasons, or for couples who wish to use donor sperm in the IVF process. It can also be used by men who are facing medical treatments (such as chemotherapy or radiation) that could potentially harm their fertility.

To cryopreserve sperm, it is collected through masturbation or by using a special condom during sexual intercourse. The sperm is then processed to remove any contaminants and to concentrate the sperm cells. It is then placed in a special freezing solution to protect it from damage during the freezing process. The sperm is then placed in a cryoprotectant solution, which helps to further protect the cells from damage during freezing. The sperm is then placed in a cryovial and placed in a controlled rate freezer, where it is slowly cooled to a temperature of -196°C or -320°F. The frozen sperm is then stored in a tank of liquid nitrogen until it is needed for fertilization.
