Cryopreservation of ovarian tissue

Modern reproductive medicine offers unique methods of preserving the possibility of conceiving a healthy child by effectively freezing germ cells, embryos, or even individual organs of the reproductive system, such as ovarian tissue.

What are the types of ovarian tissue cryopreservation?
1. Видалення і кріозаморажіванія 50% тіла яєчника з можливістю подальшої трансплантації на судинній «ніжці» по закінченню лікування супутнього захворювання (наприклад, раку). This technique is the most effective because it eliminates follicle loss due to tissue ischemia.

2. Multiple sampling and freezing of individual fragments of the ovary (cortical substance) with a size of about 5 mm cube. with the possibility of transplantation into a healthy ovary.

Показання до проведення:

Increasingly, this technique is being offered to women undergoing long-term treatment for cancer, which imposes a certain risk of reproductive system dysfunction.

The main advantage of ovarian tissue cryopreservation is that if the treatment of the disease has led to infertility, the patient still has the opportunity to become pregnant with her own cells thanks to the preserved ovarian tissue.

Переваги:

ovarian tissue for further cryopreservation can be obtained without delay, since there is no need for additional stimulation to obtain mature eggs
having a sexual partner is not necessary for a woman
a unique opportunity to preserve a large number of eggs in the follicles at the initial stage
no load on the hormonal system of the female body
There is no need to postpone the start of treatment (depending on the day of the cycle, etc.).

Preparation and/or course of the procedure

The IVMED clinic uses the Cryotissue vitrification system, which allows:

instantly freeze ovarian tissue at a speed of 23 thousand degrees per minute
eliminate the mechanism of formation of ice crystals that destroy cells
completely minimize the toxic effects of cryoprotectants on the tissue.

Vitrification is a method of rapid tissue freezing.

Features and interesting facts

The main goal of ovarian tissue cryopreservation, its preservation, subsequent thawing, egg extraction from follicles and embryo cultivation is to preserve female fertility in patients with premature ovarian exhaustion syndrome or other diseases of the reproductive system.

1996 - the first procedure of cryopreservation of ovarian tissue was performed.

In 40% of women who have undergone chemotherapy, the reproductive system functions are restored after cryopreservation of ovarian tissue.

64% of women fully restore their reproductive function after cryopreservation.

Natural growth of follicles is observed after the effect of sex hormones on the woman's body after transplantation of thawed ovarian tissue
