3. Low Progesterone during Pregnancy Can Lead to a Miscarriage. Low progesterone levels can cause complications during a pregnancy. In the early stages, it can be a sign of an ectopic pregnancy, or an indication that there is a great risk of miscarriage. If progesterone levels are below 6ng/ml during the 6th gestational week, the pregnancy is usually not viable.
Certain HPV types are classified as high-risk because they lead to abnormal cell changes and can cause genital cancers: cervical cancer as well as cancer of the vulva, anus, and penis. In fact, researchers say that virtually all cervical cancers -- more than 99% -- are caused by these high-risk HPV viruses. The most common of the high-risk strains of HPV are types 16 and 18, which cause about 70% of all cervical cancers. If the body clears the infection, the cervical cells return to normal. But if the body doesn't clear the infection, the cells in the cervix can continue to change abnormally.
High-risk HPV strains include HPV 16 and 18, which cause about 70% of cervical cancers. Other high-risk HPV viruses include 31, 33, 45, 52, 58, and a few others. Low-risk HPV strains, such as HPV 6 and 11, cause about 90% of genital warts, which rarely develop into cancer. Genital warts can look like bumps or growths. Sometimes they are shaped like cauliflower. The warts can show up weeks or months after exposure to an infected sexual partner.
