Especially due to epidemics and declining quality of life, individuals in reproductive age in the world can postpone their dreams of having a child for many reasons. Reproductive cells (eggs and sperms) obtained from these individuals with special methods are frozen with special methods without damaging these cells and turned into embryos years later in embryology laboratories, giving hope to those who want to have a child. Embryologist Abdullah Arslan gave important information about egg and sperm freezing processes.
WOMEN'S AGE IS VERY IMPORTANT
In developed and developing geographies where women are more involved in the economic cycle, reasons such as the effort to achieve economic freedom, busy working life and career prevent having children. In this rush, the probability of getting pregnant decreases as age progresses. It is known that after the age of 35, which experts accept as the limit value, egg reserve, egg number and quality begin to decrease rapidly in women. Especially after this age, the chance of pregnancy decreases to a great extent, both with assisted reproductive techniques and naturally.
WHAT IS EGG RESERVE?
Every woman is born with an average of 3 million egg cells in her ovaries when she is born. This number drops to 500 thousand with the adolescence period. The decrease in the number of eggs never stops and continues until the menopause period. In some special cases, the end of the ovarian reserve may also occur in the 20s. However, the average age of menopause is considered to be between 45-48 years. Ovarian reserve is determined by blood tests and examinations.
SUCCESS FROM FREEZING AND DEFROSTING?
Thanks to the laboratory technology, techniques and experiences that have developed in recent years, a 196% and above robustness rate is observed during the processes of freezing male and female reproductive cells and embryos obtained from them, storing them at -95 degrees, and then thawing and using them. It has been revealed by the statistical studies that the pregnancy rates obtained with in vitro fertilization treatments and embryo transfers applied after these procedures are not different from those performed freshly. It has even been found that in some special cases, pregnancy rates are higher than those with fresh treatment. It has also been determined that babies born with these treatments are healthy at the same rate as babies born with normal pregnancy in all respects.
IN WHICH SITUATIONS, EGG AND SPERM FREEZE SHOULD BE DONE?
Before radiotherapy and chemotherapy treatments, which are certain to damage reproductive cells, freezing of reproductive cells should be discussed with individuals. Again, since some surgical interventions and operations will reduce the reproductive potential, freezing and storage of reproductive cells should be considered before performing these operations. Finally, it is useful to warn that the egg cells of unmarried women who are at risk of early menopause should be frozen and stored, and they are used to achieve pregnancy after marriage. Regular control of women with a family history of early menopause is one of the most important steps to protect their reproductive potential.
