When we orgasm, tension builds around our muscles, and so when sex is over and the tension is released, it can trigger cramping, shaking or contractions can occur.

Girls typically have a growth spurt in the one to two years before menstruation starts. For most girls, puberty occurs between 8 and 13 years old and the growth spurt occurs between 10 and 14 years old. They grow just 1 to 2 additional inches in the year or two after getting their first period.

Girls usually grow rapidly during early puberty. While boys lag behind girls in height in early adolescence, they typically end up being taller than girls. This happens because after growth starts, boys grow at a faster rate and for a longer period of time.

Health experts say that as sperm is an irritant to the uterus, the uterus can react when in contact with sperms. This can result in uterine contractions, which in turn causes stomach pain and cramps.

That means you have sensitive nerves that stretch from your stomach to your scrotum. “So when the nuts are hit or squeezed, the nerve sends a signal to the upper part of the belly, which is why it hurts in the stomach when you get kicked down there,” says Darius Paduch, M.D., Ph.

The short answer is yes: You can get pregnant from pre-cum even if you’re not ovulating. Although pregnancy is most likely to happen when you’re ovulating, sperm can actually live inside your body for as long as five days.

he said that urinating after it would kill the sperm cells, is this true? It’s not true. Peeing after sex, though helpful for preventing urinary tract infections, won’t keep you from getting pregnant.

How many sperm do you need to get pregnant? 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.

While sperm and urine both pass through the urethra, they can’t come out at the same time.

Yes. You can get pregnant from the pull-out method. The pull-out method, also called withdrawal — or coitus interruptus if you wanna get fancy — involves pulling the penis out of the vagina before ejaculation.

No, you can’t get pregnant just by swallowing semen. The only way for pregnancy to occur is if sperm comes in direct contact with the vagina. Although swallowing semen doesn’t lead to pregnancy, it can put you at risk for a sexually transmitted infection (STI).

Frequent ejaculation will not cause the body to run out. Although it takes the average sperm about 74 days to fully mature, the body makes millions of sperm each day. Men with healthy, normal sperm counts should not worry about the effects of regular ejaculation.

Sperm in urinary sediment are usually derived from the first post-ejaculatory voiding [1], and in older men sperm are sometimes found in urinary sediment due to reduced contraction of the internal urethral sphincter [2].
