The woman, in her thirties, who lives in Tokyo with her husband and first-born child, had sex with the sperm donor ten times due to conceive a second child, after it came to light her husband had a hereditary disease, according to the Tokyo Shimbun.

The donor told her he was Japanese, single, and a graduate of Kyoto University, one of the best universities in Japan.

The woman, who has remained nameless in Japanese news reports, become pregnant in June 2019.

However, during her pregnancy, she learned that the donor was, in fact, Chinese, went to a different university and was married.

As a result, she decided she no longer wanted the child she had conceived with this man, but it was too late to terminate the pregnancy.

After giving birth, she gave the child up to the state and last month filed a 330 million yen ($2.86 million) lawsuit against the sperm donor for emotional distress.

Tokyo Shimbun reports that the woman said he tricked her for the sake of sexual gratification.
