Reproductive System

The reproductive system relies on the endocrine system for hormone regulation, which is crucial for processes like ovulation and sperm production. The nervous system also plays a vital role by influencing sexual arousal and reproductive behaviors through signaling. Additionally, the circulatory system is essential for delivering hormones and nutrients to reproductive organs, while the immune system helps protect against infections that could affect reproductive health. Together, these systems ensure the reproductive system functions effectively and maintains overall health.

It is the area on the testicle where the vas deferens connects to the testicle. I might feel like a small knot or bump.

Many can reach the ovum but only one can penetrate and fertilize it.

Age structure is the general term used to describe the different levels, if you will, of various age groups. For example, those of reproductive age are of "child bearing age."

Fertilization happens in the uterus.Look at the picture below:

In women, pelvic ultrasound is used to examine the uterus, ovaries, cervix, and vagina.

The starfish has 10 digestive glands. 2 in each of its 5 arms.

All of the parts of the female reproductive system have a role in reproduction. Some key organs are the ovaries that make the eggs, the fallopian tubes that carry an egg to the uterus, and the uterus where the embryo begins to develop.

sperm competition.

Since the dawn of the sexes, males have vied with each other to get as many of their own sperm near a fertile egg as possible. Getting more of your sperm closer to an egg means there is a greater probability that it will be you and not your neighbor fertilizing it.

Your vagina should smell musky but clean, it may be stronger if you need to bathe but shouldn't smell bad. If your vagina smells bad, such as like fish or ammonia, it's a sign of a vaginal infection such as Bacterial Vaginosis. See your doctor for tests and treatment.

For men, yes, it clears out the urethra pretty well. There will be very few sperm left.

For women it makes no difference at all. Urinating does not reduce or wash out any sperm in the vagina at all. This is because the vagina is not part of the urination process.

The usual site of human fertilization is the uterine (or fallopian) tubes.

The role of a sperm cell is to travel or 'swim' in a liquidy substance called 'semen' (produced from the testicular glands located internally in the males reproductive organ). It travels through the cervix of the female reproductive organ, though the uterus and up the fallopian tube. (Depending on which day of the premenstrual cycle) The egg cell that is released from the ovary travels about half way down the tube. One of the millions of sperm cells is then connected with the egg cell, to which it quickly closes to prevent two cells getting in. The tail then falls off and the two nuclei join in the middle. This is the process of fertilisation. A fetus will then grow and 9 months later, hopefully a baby is produced.

The male sticks his Penis in the females vagina and humps.... And his testicles hold and make the sperms, and as he humps the female, sperms enter inside the vagina, and sooner or later the female grows a baby to give birth soon.

the male testes are protected by the scrotum. a layer of skin covering the "ball sack".

Not with his own semen. Though if he came into contact with another man's semen (having sex with another man or even a woman who recently had sex), then the "foreign" semen could impregnate the woman.

The female ovaries are generally developed about 100 days after fertilization. The male testis do not descend into the scrotum until the ninth month of development although this sometimes occurs after birth.

If you mean sperm floating around in the pool, it would be exceedingly unlikely to get pregnant.

If you mean having sex while in the pool, then it is just as likely to get pregnant as if you were in a bed.

But it is important to remember, even if you have sex and then pull out and ejaculate into the water she can still get pregnant since pre-ejaculate (pre-cum) also has a small amount of sperm in it.

Puberty or maturity is the term for the onset or reproductive life. A related term, menarche, means the first menstrual period.

I was still on the pill when I became pregnant in September 2007. The pregnancy felt normal and I was progressing on. I had my first u/s in the beginning of November and was told that I had a blighted ovum. I was devastated. You become a mother the minute you find out you are pregnant. I waited a week for the natural progression. I did not want to have a d-an-c so I waited. I spotted a bit and every time thought this is it. It was never that time- I ended up taking the pill. I took it about 3 pm one afternoon (I was told to take it in the afternoon so I am not up all night into the early morning)- very good advice. I started having contractions at 3:30 pm. That pill works fast! I had 8 hours of stomach pain (labor like). Do not take that pill alone- have someone with you to hold your hand. There is a lot of bleeding involved... and if you over bleed (fill up a pad in short period of time) go to the hospital. It did not go that far for me- thank god! I would say it was about 11 pm the same day that I went to sleep. The next morning I felt fine and at about 3 pm. I had the urge to go to the bathroom where I delivered a small sac. I didnt even look at it - I just thought it was amazing that my body was even doing this..... I thought it was all going to be just bleeding- not full on delivery.... it was crazy.

I am doing well now- and have not conceived again as I am not sure I am ready. I am afraid this happens again even though I have choosen to stay off of the pill. I can say that hormones are not good for you and I would say that the pill can cause a blighted ovum or other chromosonal probelms.

It depends on weather. It gets larger on hot days and shrink in cold weather.
