Kim Jaejoong revealed his experience of sperm freezing on KBS2’s ’New Release Ppongstorang.’

On the show, Kim Jaejoong invited his close friends Choi Jin-hyuk, Yoon Si-yoon, and Yoo Seon-ho to his home, serving them health-boosting dishes he made himself while having an honest conversation about marriage and preparing for children. Kim Jaejoong said, ″Men also need to prepare well for having children,″ and disclosed that he had frozen his sperm in the past to ensure healthy preparation for offspring. He explained, ″You need to preserve your genes when you are young to have healthy children.″

Referring to the sperm freezing process, Kim Jaejoong shared, ″When you enter the doctor’s room at the hospital, you first have to take off your pants. They check if there is anything abnormal externally.″ He continued, ″You enter the ’room of truth,’ and that’s where the problem arises. If you finish too quickly or too late inside, there will be an issue. You have to keep the golden time. Outside, they loudly call out ’Mr. Kim Jaejoong.’ I wore a mask and went secretly, but when they call your name, people look. It’s really embarrassing.″ He also added, ″That’s actually the test. The first test determines whether freezing is possible. There are two embarrassments.″

Regarding sperm freezing, Kim Jaejoong stated, ″Sperm remains healthy for three years, and after five years, it is discarded. Mine has been discarded now. I don’t plan to do it anymore.″ In response, Choi Jin-hyuk said, ″I should do it too. But because of that, I can’t bring myself to go. I don’t have the courage.″

Kim Jaejoong was born in 1986 and is 40 years old this year. He debuted in 2003 and is currently active as a solo singer and producer.
