If your Nuvaring comes out, then your chances of pregnancy are the same as any female without contraceptive protection.

it is a natural change in vaginal external skin during pregnancy.

The site of fertilization is the ampulla part of the fallopian tube.

There are a number of types of abnormal growth of tissues in the inner lining of the fallopian tubes or uterus. These include polyps, fibroids, and cysts.

The role of the prostate is to produce a liquid that mixes with semen and helps the sperm move through the semen into the woman's body.

When a prostate becomes enlarged, it can effect the production of the fluid. In most cases of BPH, as the prostate becomes enlarged, it impacts your ability to urinate, due to putting pressure on the bladder.

Also, an enlarged prostate can lead to prostate cancer if not treated.

i believe it to be a primal instinct...because if we didn't...i wouldn't be here to write this as you wouldn't be here to read it. However, the so-called instinct is driven by hormones and pheromones.

the testes are where sperm are manufactured in the scrotum. The epididymis is a tortuously coiled structure topping the testes, and it receives immature sperm from the testis and stores it several days. When ejaculation occurs, sperm is forcefully expelled from the tail of the epididymis into the deferent duct. Sperm then travels through the deferent duct through up the spermatic cord into the pelvic cavity, over the ureter to the prostate behind the bladder. Here, the vas deferens joins with the seminal vesicle to form the ejaculatory duct, which passes through the prostate and empties into the urethra. When ejaculation occurs, rhythmic muscle movements propel the sperm forward.

Go and see a qualified medical practitioner (a doctor) about it.
