Recent studies:
"In the study, researchers tested semen samples and vaginal secretions from three groups of patients: control subjects without evidence of Lyme disease, random subjects who tested positive for Lyme disease, and married heterosexual couples engaging in unprotected sex who tested positive for the disease. As expected, all of the control subjects tested negative for Borrelia burgdorferi in semen samples or vaginal secretions. In contrast, all women with Lyme disease tested positive for Borrelia burgdorferi in vaginal secretions, while about
half of the men with Lyme disease tested positive for the Lyme spirochete in semen samples. Furthermore, one of the heterosexual couples with Lyme disease showed identical strains of the Lyme spirochete in their genital secretions. The presence of the Lyme spirochete in genital secretions and identical strains in married couples strongly suggests that sexual transmission of the disease occurs,” said Dr. Mayne."

f1000research.com/articles/3-309/v3"initial laboratory testing of semen samples provided by male Lyme patients (positive by western blot/PCR in blood) and the male sexual partner of a Lyme infected female patient were positive approximately 40% of the time. PCR recovery of Lyme DNA nucleotide sequences with microscopic confirmation of semen samples yielded positive results in 14/32 Lyme patients (13 male semen samples and 1 vaginal pap). ALL positive semen/vaginal samples in patients with known sexual partners resulted in positive Lyme titers/PCR in their sexual partners. 3/4 positive semen patients had no or unknown sexual partners to be tested."
