A regulation regarding egg-freezing has sparked wide public debate among Chinese social media netizens.

The law, made by China's Ministry of Health in 2001 and revealed by state media CCTV through its official Weibo account on Sunday, bans unmarried Chinese women from freezing their eggs.

Many Internet users have been questioning the rationality of this regulation.

Han Han, one of China's most popular writers/bloggers, criticized the regulation through his Weibo account, saying "the rule blocks single women's right of having a baby." Some Internet users argued the regulation is a discrimination to bar single women from having their eggs frozen.

Under current laws in China, only married women with birth permits are allowed to use the egg-freezing policy.

Furthermore, before using this option, couples must present their marriage certificate, identity cards, birth permits and medical records which show that at least one partner is suffering from fertility difficulties.

Because of the rule, more and more single Chinese women are going abroad to have their eggs frozen.

A new statistic revealed by Chinese media outlet, "The Paper", shows that 90 percent of Chinese women who take egg-freezing operations abroad are single and most of them are between the ages of 30 to 37 years old.

The egg-freezing technology is gaining increasing popularity in China after Xu Jinglei, a famous Chinese actress made it public that she had her eggs frozen in the U.S.

Lin Chi-ling, an actress from Taiwan, also said she had used the operation before.

Egg-freezing, or ocyte cryopreservation, is a procedure where a woman's ovums are removed, frozen and placed in long-term storage.

When the woman is ready to become pregnant, the eggs can be thawed, fertilized and transferred into her uterus.

Technically, frozen eggs can be preserved indefinitely, but the international norm is five years.

Although the technology gives hope for women to realize their motherhood dreams, medical experts have been advising people to be cautious, given that the technology is still primitive with success rates of below 50%. Moreover, the older the woman is, the lower the success rate.

Doctors also say that when women use the technology to have children at an advanced age, they're at a greater risk of suffering from hypertension and diabetes.

So far, little is known about the potential risks to a baby born from a frozen egg.
