When is ovary tissue preservation necessary?

  1. At cancerTo preserve reproductive function (fertility) in women and girls who have not reached puberty

    Hodgkin’s lymphoma (lymphogranulomatosis, Hodgkin’s disease).  
    The risk of the loss of fertility as a result of:
    – chemotherapy prescriptions, depending on the treatment protocol – ≤ 10-50%
    – transplantation of hematopoietic stem cells – 70-100%

    Leukemia (leukosis). 
    Treatment does not decrease fertility, but may affect reproductive potential

    Ovarian cancer.
    High risk of infertility due to radiation and chemotherapy

    Cervical cancer.
    High risk of infertility due to radiation and chemotherapy

    Tumors of the brain and spinal cord. 
    High risk of infertility due to radiation and chemotherapy

    Removal of the ovary or its part.
    Infertility occurs or may occur

    Non-Hodgkin’s lymphoma. 
    The risk of fertility loss as a result of:
    – chemotherapy, depending on the treatment protocol – 5-14%
    – transplantation of hematopoietic stem cells – 70-100%

    Breast cancer. 
    The risk of fertility loss as a result of chemotherapy, depending on the treatment protocol – 33-65%

    Endometrial cancer of uterus. 
    The risk of fertility loss as a result of treatment at the late stage of the disease – 100%

    Ewing’s sarcoma. 
    High risk of infertility due to radiation and chemotherapy

    Bone marrow transplantation (hematopoietic stem cells). 
    The risk of loss of fertility is 70-100%.
  2. In the case of delayed pregnancy. . For women after 30 years of age who, for some reasons, have postponed the birth of a child, there is a risk of fertility loss due to depletion of the ovarian reserve

    Ovarian reserve. 
    These are 300-400 thousand follicles that are in the ovaries of a woman. After puberty and before menopause, a woman loses about 1000 follicles every month. Ovarian reserve is fully exhausted by the age of 45-50 years

    Evaluation of ovarian reserve. 
    It is possible to determine how much time is left before the loss of fertility by calculating the number of follicles capable of ovulation in the ovaries and the rate of their loss. This is done by high resolution ultrasound and the determination of the level of Anti-Müllerian hormone and estrogens

    Cryopreservation of ovarian tissue.  
    .It is a policy of “biological insurance” and in the future, if you can not conceive a child in a natural way due to a decrease in ovarian function, you will be helped by your own healthy ovarian tissue
