Is the Fundamental Reason for the Popularity of Egg Freezing in the U.S. the Irreversibility of Female Germ Cells?

Female fertility is a complex and delicate process that is significantly different from male germ cell production. While men can produce a new batch of sperm every 72 days, women are born with approximately one to two million oocytes in their ovaries. As they age, this number gradually decreases; by puberty, the number of oocytes drops to between 300,000 and 500,000, continuing to decrease in the following months. During ovulation, only one mature egg can be released, while the other eggs will naturally die through apoptosis. By the time a woman reaches 37, her oocyte count may drop to around 25,000, and by 51, many women have entered menopause, leaving approximately 1,000 oocytes in their ovaries.

In addition to age, female fertility is influenced by a variety of factors. Genetic factors play an important role, as some women may experience a faster decline in their egg reserve than others. Furthermore, lifestyle and environmental factors cannot be ignored. For example, smoking has been shown to have toxic effects on egg health, and heavy smokers often enter menopause at a younger age. Additionally, obesity can reduce a woman's chances of becoming pregnant during any given menstrual cycle, with women who have a higher body mass index (BMI) significantly less likely to conceive compared to those of normal weight.

Sexually transmitted infections, such as chlamydia or gonorrhea, can lead to blockages or scarring in the fallopian tubes, affecting fertility. Hormonal imbalances can also disrupt normal ovulation processes; conditions like polycystic ovary syndrome and endometriosis can affect women's fertility. Women who have undergone cancer treatment may also experience impaired ovarian function, leading to disrupted ovulation.

Given this multifactorial impact, it is particularly important for women to consider their age when planning for pregnancy. Attempting to conceive before the age of 35 can increase the chances of success. For those planning to delay childbirth due to work, life, or other reasons, egg freezing is a viable option. By timely freezing healthy eggs, women can create more opportunities for fertility in the future.
