You can also get pregnant using different kinds of alternative insemination or in-vitro fertilization. During alternative insemination, semen is inserted into your vagina or uterus using a syringe or other device. You either put the semen in at home by yourself or with a partner, or with the help of a doctor.

In artificial insemination, a doctor inserts sperm directly into a woman’s cervix, fallopian tubes, or uterus. The most common method is called “intrauterine insemination (IUI),” when a doctor places the sperm in the uterus.

The donation process is simple. The man walks into a private room which is usually stocked with pornography and masturbates into a sterile container. The semen sample is collected from the container and is mixed with a cryopreservative solution, divided in aliquots, sealed in vials and frozen with liquid nitrogen.

Men should not ejaculate for two days before sperm will be collected for IVF, but they should not have gone without ejaculating for longer than five days either.

A recent study published in PLOS ONE finds that frozen sperm retrieved via testicular biopsy is as good as fresh sperm in leading to a successful pregnancy through IVF. The finding should make it easier to organize IVF procedures and increase options for infertile couples.

Researchers found that men ages 40–49 that ejaculated more frequently had a lower risk of prostate cancer. Men with the lowest risk ejaculated at least 21 times per month. The study did not establish that ejaculation could prevent cancer in younger men.

Female ejaculation, that is oft en contributed to the G-Spot, actually comes from the glands around the urethra in front of the vagina (Skene’s glands), and is often brought out by the muscle contractions that come with orgasm. This fluid is obviously not urine, however may look like it.
