Noting that egg freezing can be done in two different situations in women, Assoc. Erhan Şimşek: “The first is to prevent loss of egg reserve after cancer treatment in oncology patients. In the second group, there are healthy women with reduced ovarian reserve due to age-related or genetic inheritance from the family. However, this age is not the same for every woman. The fertility rate, which is expected to normally decline between the ages of 30-35 and accelerates each year between the ages of 35 and 45, falls at a much younger age for women. some women. “Less than 50 years old can give birth on their own without assisted reproductive technology. Recently, the pregnancy period, which has been delayed beyond the age of 35, along with college, graduate, doctoral, career and business planning processes have negative impact on the rate of conceiving,” she said.
‘Pregnancy chance can remain with egg freezing’
associate Dr. Şimşek said: “Especially today’s modern living conditions, conditions such as education and work, cause the age of conception to be postponed to higher ages. Since the decline in fertility from the mid-30s is inevitable, the need for fertility preservation methods, such as egg freezing, is increasing day by day in a group of patients. Today, there are extremely good opportunities to obtain and store eggs to maintain fertility in the future. For the past 10 years, our Department of Health has been giving women who want to become mothers the chance to preserve their fertility as they reach old age and as their eggs decline. For these patients, the chance of getting pregnant using the eggs they have frozen before marriage remains after marriage,” he said.
‘Egg freezing also applicable to oncology patients’
Emphasizing that freezing can be applied to patients with reduced egg reserve, who are considering pregnancy at an advanced age, who have oncological problems, who will undergo chemotherapy or who will undergo a bone marrow transplant, Şimşek said: “Eggs can be used in the most efficient way to Ages 38-40 We recommend our patients considering this procedure to be examined by a physician who specializes in IVF or reproductive health between the ages of 30-37 and to evaluate their ovarian reserves. number of eggs in some of the 35-year-old patients is lower than expected, indicating that there is not much time left to freeze the eggs Even if more eggs can be collected later in life, the chance of pregnancy is possible not large.Therefore, age is an important factor.For women who are not yet married, egg freezing can be done with the examination and guidance of a specialist doctor. Egg reserves can also be evaluated by ultrasound and the antimullerian hormone test, which can evaluate egg reserve from blood samples when determining egg reserve. Oncology patients who have enough oocytes are at risk of losing their healthy oocytes after chemotherapy treatment or bone marrow transplant. For our oncology patients who meet the right conditions, egg freezing before treatment is an important option to preserve their fertility in their future lives. The permanent decline in fertility that occurs with treatments that damage the ovary and carry the risk of menopause, such as chemotherapy and radiotherapy, can be largely prevented by using these methods.
“Matured eggs can be collected in a 10-15 minute process”
Şimşek noted that egg freezing is similar to in vitro fertilization and said, “The eggs, which take about 10-15 days to mature through the patient’s own daily injections from the abdomen, can be painlessly collected in a short procedure of 10-15 minutes.After the eggs are collected, DNA identification is carried out and frozen in tanks with liquid nitrogen at -250 degrees.The thawing process and fertilization of the eggs can be carried out quickly after 10-15 days of treatment.The storage period of frozen eggs, which has been set at an average of 5 years, can be renewed annually with an application to the Department of Health.
“It’s important to do it in equipped centers”
Şimşek mentioned that egg freezing is performed similarly to in vitro fertilization procedures, saying, “With the counseling services and proper treatments that can be received in equipped centers, these procedures can be performed. The number of frozen oocytes is an important determining factor in our patients who want to become pregnant after oocyte freezing. For this reason, it would be an appropriate approach to complete procedures before it is too late and egg reserves are depleted in women at risk. Although the woman’s age at the time of egg freezing is quite a determining factor, the aim is to freeze enough eggs so that the patients’ pregnancy rates can be high when they get married. Ideally, collecting about 10 eggs for a significant chance of pregnancy yields a significant pregnancy rate. It aims at high pregnancy success by collecting eggs several times in a row in patients with a lower egg count.
