The human reproductive system is all about how the timing, hormones, male and female reproductive systems (sperm and egg). First, in order for a baby to come into this world, the male and the female reproductive systems must work correctly. Both male and female has their own/different parts that work in order for a baby to be conceived. Although the male and the female reproductive systems are different, once they meet and come together they work together to make a baby at the end of result.

The male’s reproductive system produces something called a sperm; a tadpole like cell. It is said that when a male is to ejaculate, there are about 40 million to 600 million sperms are released at that one time. In that 40 million to 600 million sperms only about 5 million to 20 million are fertile, and the rest are infertile. Epididymis is another part of the males’ reproductive system. This is where the sperms get its nutrients and grows to be mature. It’s made up of smooth muscle cells; tube that is 20 feet in length on the posterior or the back side of each testis which are tightly coiled. Ductus deferens, also called the vas deferens; it measures up to be about 14 inches (35 centimeters) in length to an average adult male. This is where the sperm is moved along their smooth muscular wall. Ejaculatory duct is a short passageway that was made up by the vas deferens and duct of seminal vesicles. This is where the ducts empty the sperm and fluid into a single urethra; its measurement is just less than 1 inch. Urethra is another part to the male reproductive system; the male urethra extends from the urinary bladder to the tip of the penis (measures up to 6 to 8 inches in distance). In the male urethra, it can serve as a reproductive and urinary system. It transports the sperm and urine out of the body. However, it will never release both the sperm and urine out of the body at the same time. When a sperm enters the urethra from the ejaculation, the muscles junction of the bladder and urethra closes up. In result, it keeps the urine in the bladder and keeping the sperm from entering the bladder (No mix up). Another male reproductive system contains the accessory gland and semen. The accessory gland has three glands which makes the semen which has a whitish color and rather sticky mixture to it. At an average ejaculation, it releases about 0.05 to 0.17 ounces of semen. The first gland (seminal vesicles) located at the base of the bladder adds secretion to the sperm (makes up about 70% of the seminal fluid). The vesicles are about 2 inches in length. Second, the prostate gland is a single rounded gland that makes a milky, acidic secretion that enters the urethra, and this makes up about 10 to 30 percent of the seminal fluid. Last is the bulb urethral glands, it is a tiny pea shaped glands located underneath the prostate gland on either side of it, they give off a clear mucus look that is thick. These glands are very important to the males because of the bacteria present in the females vagina can make and acidic environment; but with the alkaline seminal fluid from the male neutralize the acid given off by the vagina and let the sperm enter the vagina and go up so that fertilization can take place.

The female reproductive system is more complicated than the males. The female reproductive system carries what is called the “Egg” or the “ova” and it makes a space big enough for the Ovum to be fertilized and to be develop until birth. The female has what is called ovaries. Which are two almond spaced structures which are located on each side of the pelvis and measures up about to 1.2 inches in length; also this is where the ovarian follicles are there. Ligaments connect to the ovaries to the wall of the pelvis and to the uterus. Its purpose is to protect the egg and about 360 to 480 ovarian follicles will make mature egg. There is another part called the fallopian tube. The fallopian tube (which is also known as the uterine tubes) connect...
