    Many single women around the world are having their eggs frozen, but experts recommend doing it before they hit 35. 
    According to figures from fertility clinic CHA Medical Center, some 1,194 single women here had their eggs frozen last year, a two-fold increase from 2020. A decade ago, fewer than 10 women had their eggs frozen. 
    Frozen eggs can be stored for more than 20 years. 
    Koo Hwa-seon at CHA Medical Center in Bundang said, "Anti-Müllerian hormone (AMH) tests can determine the number of potential eggs a woman has left to produce. If you approach your mid-30s, you should visit an ob-gyn clinic once a year to check your ovarian age." 
    Men can also have their sperm frozen, but they do not have dramatic fluctuations in their sperm count until they reach 50. 
    Women who wish to have their eggs frozen must self-administer hormone injections every day for about eight days prior to the procedure. Usually, around 20 eggs are frozen and it costs around W2.5 million (US$1=W1,326).
    "In the past cancer patients used to have their eggs frozen before chemotherapy and got pregnant through in-vitro fertilization after they were cured," Koo said. "These days, more and more women are simply having their eggs frozen because they're getting married later in life." 
    "Women who marry later in life want to have children, but their eggs deteriorate, making even in-vitro fertilization difficult," Koo said. "Freezing eggs is a form of insurance that should be done when a woman is in her mid-30s or younger."
