In vitro ejaculation is a relatively safe form of sexual intercourse, but there are some potential risks and adverse consequences. In vitro ejaculation on the first day of ovulation may bring the following benefits and risks.

However, there are some potential risks and adverse consequences associated with in vitro ejaculation. First, external ejaculation may cause men to be unable to fully control their sexual impulses during sex, resulting in unskilled sexual behavior and may even lead to orgasm. Secondly, in vitro ejaculation may reduce men's sexual ability and lead to a decrease in the quality of sexual life.

Therefore, ejaculation is not an ideal form of sexual intercourse for couples who want to have children. If couples want to have children, it is recommended that they adopt other safe methods during sexual intercourse, such as oral sex, masturbation, intercourse, etc. In addition, couples should also pay attention to personal hygiene to avoid contracting sexually transmitted diseases.

In summary, while there are some benefits to in vitro ejaculation, there are also some potential risks and adverse consequences. Therefore, couples should pay attention to choosing safe and healthy sexual methods when having sexual intercourse to avoid contracting sexually transmitted diseases.
