Semen can be a hotbed for viruses, scientists report in the November issue of Emerging Infectious Diseases. At least 27 viruses can live in the fluid, including Ebola, Marburg, chikungunya and Lassa fever.
Can you be physically allergic to sex? Up to 40,000 women in the United States are believed to have a semen allergy. Although this sexual sensitivity is rare, Dr. Bednarek says that semen changes the pH balance in the vagina for some women, resulting in irritation, cervical mucus, hives, and swelling.
Those include the viruses that cause Ebola, HIV, hepatitis B, and herpes. After reviewing more than 3800 scientific publications, the authors also found evidence that at least 11 viruses can live in the testes, including those that cause influenza, dengue, and severe acute respiratory syndrome.
Researchers have found that exposure to semen is good for women's health because of the mood-altering chemicals of this body fluid. Earlier research had shown that these chemicals not just elevate mood, increase affection and induce sleep, but also contain vitamins and anti-depressants.
Semen is alkaline and the vagina is acidic, which means unprotected sex with a male partner may disrupt the natural balance of bacteria within your vagina. Unprotected sex with a male partner can also lead to STIs like chlamydia, gonorrhoea and HIV, as bacteria and viruses can be carried in semen and pre-cum.
Sperm bacterial contamination is quite frequent and could contribute to the deterioration of the sperm quality of infertile men.

There is no specific frequency with which a man should ejaculate. There is no solid evidence that failure to ejaculate causes health problems. However, ejaculating frequently can reduce the man's risk of getting prostate cancer. Ejacu-lation can be through having sex or masturbating a few times a day.
Thick semen usually results from a higher than normal concentration of sperm in a typical volume of semen, or from having a high number of sperm with an irregular shape (morphology). High sperm concentration often indicates that you're more likely to impregnate a female partner.
There are two types of sperm cells: X sperm and Y sperm. X sperm: X sperm on combining with the X chromosome of the female produces a zygote with XX chromosomes.
For the most part, yes, the components that make up semen are safe to ingest. Swallowed semen is digested in the same way as food. However, in very rare circumstances, some people might discover that they're allergic to semen. This is also known as human seminal plasma hypersensitivity (HSP).
Yep, you can be allergic to your sexual partner's semen. This is called seminal plasma hypersensitivity. It happens when a person is allergic to certain proteins in semen.
Clear, white, or gray semen is considered typical or healthy.
It is quite normal for semen to form jelly-like globules and this does not indicate any health or fertility problem. Failure of clotting and subsequent liquefaction can cause fertility problems. Semen clots almost immediately after ejaculation, forming a sticky liquid.
Some research suggests that increasing body mass index (BMI) is linked with decreasing sperm count and sperm movement. Eat a healthy diet. Choose plenty of fruits and vegetables, which are rich in antioxidants — and might help improve sperm health. Prevent sexually transmitted infections (STIs).
The life span of sperm after ejaculation depends on the circumstances. Ejaculated sperm remain viable for several days within the female reproductive tract. Fertilization is possible as long as the sperm remain alive — up to five days. Sperm can also be preserved for decades when semen is frozen.
Painful ejaculation may be a sign of a larger medication condition that requires treatment. Common causes include prostatitis, surgery, cysts or stones, and antidepressant drugs. See your doctor for diagnosis and treatment so that you can avoid serious complications and maintain a healthy sex life.
Sperm with many tails also have Macrocephaly, meaning that multiple tailed sperm come with the same problems as their big-headed associates: their chromosomal makeup is abnormal and therefore results in failed pregnancies and miscarriages when meeting with the egg.
It takes just one sperm to fertilize a woman's egg. Keep in mind, though, for each sperm that reaches the egg, there are millions that don't. On average, each time men ejaculate they release nearly 100 million sperm. Why are so many sperm released if it takes only one to make a baby?
The concentration of sperm is what makes the semen cloudy and thick, so if your ejaculate is watery it is possible that you have a low sperm count. This doesn't mean you're infertile (so precautions to prevent pregnancy still need to be taken for couples that don't want to get pregnant).
That depends on many factors and can vary from time to time. Measured on a stopwatch, it takes an average of 5 to 7 minutes for a man to reach orgasm and ejaculate. But the overall range is wide, from less than one minute to over half an hour.
They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm.
Male sperm is normally thick and white in color. However, certain medical conditions and lifestyle factors can change the color and consistency of sperm. Watery sperm does not have that thick semen texture. Instead, it is more 'liquidy'.
