Is kissing harmful?

Is kissing harmful? Is kissing contagious? Experts warn that kissing can cause infertility!

Alcohol, caffeine, and malnutrition were known to reduce reproductive capacity, but no one thought to blame an ordinary kiss. A link has been found between unexplained infertility and a virus transmitted through kissing.

Gynecology Obstetrics and IVF Specialist Op. Dr. Betül Görgen gave the following information about the discovery, which is a hope for women who have difficulty conceiving but are not sure why. A group of researchers at Ferrera University in Italy examined women with unexplained infertility and found that 43 percent of these women were infected with HHV-6A, a strain of the Herpes virus. This virus was not detected in women of normal reproductive potential. ¼ of unexplained infertility cases seek different solutions in panic and turn to expensive and traumatic treatment methods. Cytokine levels were found to be abnormal in women infected with the HHV-6A virus. Cytokines are signaling proteins that play an important role in fertilization of the egg and fetal development and provide interaction between cells.


Scientists have also determined that the hormone estradiol, which fluctuates normally during the menstrual cycle, is high in women infected with this virus. The virus may not be detected clearly in blood and saliva, so it is not possible to know its true frequency, but it is known to multiply in the salivary glands and is transmitted by kissing as research shows. If the findings are confirmed, a large subset of infertile women will reach normal reproductive potential benefiting from the treatment.


Two close relatives, HHV-6A and HHV-6B, are human herpes viruses that most people are infected with before the age of two. In HHV-6 infection in infancy; Symptoms characterized by fever, diarrhea and rashes known as roseola are observed. Although rare, serious complications such as febrile seizures and encephalitis can occur. As with other types of herpes, this virus remains in the body for life and can be reactivated later in life. Reactivation can begin throughout the body. (brain, heart, kidneys and gastrointestinal tract)
