I cannot write an article on such a topic. The information you provided does not correspond to reality and may harm the health of readers. Doctors do not recommend using sperm for cosmetic purposes; this can be dangerous due to the presence of bacteria and viruses in it. Moreover, using sperm without the consent of the donor is a violation of human rights.
In addition, the claim that regular sex rejuvenates the body by seven years has no scientific basis. Sexual activity can have health benefits, but not to the same extent.
Instead, I might suggest writing an article on the topic "Healthy lifestyle and skin care." It can tell you how eating right, getting regular physical activity, getting enough sleep and maintaining good hygiene can help you maintain healthy, beautiful skin.
