The body fluid is host of the virus, which is associated with 98% of cervical cancer cases
In Mexico every two hours a woman dies of cervical cancer, which is associated in 98 percent cases of human papilloma virus (HPV) and of this percentage, 70 percent is related to types 16 and 18 , considered high-risk strains.
Researchers at the National Medical Center November 20 Institute of Security and Social Services for State Workers (ISSSTE) studied the presence of HPV in the semen, as most studies in this regard are focused on women.
Ignacio Flores, physician assigned to the area of human reproductive biology of that hospital, he told La Jornada that the research team found that 60 percent of semen samples analyzed (corresponding to 149 patients a protocol for assisted reproduction the institution) was a carrier of HPV types 16 and 18.Extra Hazard
Flores said that other studies show that the virus has been found attached to the head of the sperm. Yet known whether the germ can "penetrate" in the male reproductive cell and the implications in the fertilization process.
However, it is possible to determine that the seminal fluid can be a driver of the microbe and it can be implemented in other structures such as the epithelium of the endometrium or fallopian tubes, without adverse effects on male reproductive system itself.
"As a vehicle for the virus, hypothetically semen can infect other female reproductive structures, potentially can carry out fertilization anomalous condition may cause abortions or preterm pregnancies," the gynecologist, so it is necessary to open research to determine the impact on reproductive phenomena. "
So far, it was known that the human papilloma virus had a predilection for epithelia, such as the cervix, vagina, vulva or in the case of men, the urethra, to incubate.
However, the study-won first place in the scientific work LXI Mexican Congress of Gynecology and Obstetrics 2010 in Chihuahua, showed that the pathogen may be present in seminal fluid.
Notes that despite the positive seminal high-risk HPV, the study subjects were asymptomatic, which represents a health problem because they can infect your partner every time you have no discomfort or symptoms.
The doctor also said that on average, patients began their sexual life at age 17 and had six sexual partners, two risk factors for infection.
Flores stressed the importance of promoting responsible sexuality among adolescents, because HPV is extremely contagious and the young are more susceptible to sexually transmitted infections.
On the applicability of the HPV vaccine in men, the human reproductive specialist said he can not tell what impact, as suggested further research.
Flores estimated that each year are carried out between 500 and 700 artificial insemination procedures that use samples of semen banks, so he insisted on the importance of legislating on the matter, since these centers can assist in spreading virus, since it does not ask for any HPV screening and "do not know what effects it could have on fertilization and possible contamination of the woman."
