In Hungary, ovarian tissue freezing was performed for the first time in prepubertal children treated for oncological diseases at the Semmelweis University Pediatric Center. During the procedure, the ovaries are removed, frozen and then transplanted back into the abdominal cavity in adulthood, in order to enable later childbearing. The side effects of certain medical treatments of childhood cancers (chemotherapy, radiotherapy, bone marrow transplants) can lead to poor ovarian function, hormonal imbalances and eventually infertility.<\/div>\n

\"\"<\/a>\u201cWe remove the right or left ovary, or part of it, through the navel, using a procedure called laparoscopy,\u201d says Dr. Zita S\u00fck\u00f6sd, a specialist and the first surgeon to perform such surgeries at the T\u0171zolt\u00f3 Street Department, Pediatric Center. \u201cThe aim is to make the procedure as gentle as possible on the child’s body, so we make only three small incisions in the skin and remove the ovary with long, thin instruments without damaging the fallopian tubes. The tissue is then divided into several sections, frozen and stored in liquid nitrogen air at -196 degrees Celsius at the Division of Assisted Reproduction at the University’s Department of Obstetrics and Gynecology until the patient reaches the age of 25, which can be extended every five years thereafter if necessary,\u201d explains the specialist.<\/p>\n

In Western Europe and America, experience with childhood ovarian tissue freezing has been positive. There, too, this procedure is used primarily to prevent ovarian depletion and later infertility, added Dr. Zita S\u00fck\u00f6sd.<\/p>\n

\n

The surgery, which used to be only accessible to adults in Hungary, is now available for children at Semmelweis University, where specialists have already performed five procedures on children of different ages in recent months.<\/p>\n<\/div>\n

International data show that there are already hundreds of known cases in adults where patients who have received oncological treatment have given birth to a healthy child as a result of this procedure.<\/p>\n

\"\"<\/a>Dr. D\u00e1niel Erd\u00e9lyi, a hematologist at the T\u0171zolt\u00f3 Street Department, Pediatric Center of Semmelweis University, explained that the procedure is still in the research stage for children worldwide, despite that there are several known cases where a girl, operated under 18, in childhood, gave birth to a healthy offspring later in life thanks to the subsequent ovarian transplantation. \u201cIn line with international practice, we have been given permission to perform this procedure only before treatments with a high risk of infertility. We estimate that we can enrol 20 to 30 patients annually from all over the country,\u201d the hematologist pointed out.<\/p>\n

As a major advantage of the surgery, there is no visible scar, and the patient can be discharged home on the same or the following day after the one-day surgery.<\/p>\n

\n

Pediatric oncology has evolved rapidly in recent decades, which is why new procedures are needed that improve not only the survival but also the quality of life,<\/p>\n<\/blockquote>\n

explains Dr. D\u00e1niel Erd\u00e9lyi. With this procedure, specialists are creating the possibility for cured children to start their own families in the future by preserving their fertility.<\/p>\n
