The male reproductive system consists of a number of sex organs that plays roles in the process of human reproduction. These are the penis, the urethra, the scrotum, testes (testicles), vas deferens, seminal vesicles, and prostate. Unlike women, majority of these organs are located on the outside of the body. While the penis and the urethra (the tube through which urine passes) are part of both the urinary and the reproductive systems, the scrotum, testes (testicles), vas deferens, seminal vesicles, and prostate comprise the rest of the reproductive system.
This is a measure of the number of spermatozoa inside each ejaculation or inside a quantity of of semen. This count is used as an indication of a man’s fertility. A normal sperm count should have 40 million to 300 million sperm per milliliter pf semen. Counts below 10 million are considered poor; while sperm count of 20 million or more may be fine if the sperm’s structure and motility are okay.
An erection is a hardening of the penis that occurs when tissue inside the penis fills up with blood. Usually, an erection causes the penis to enlarge and stand away from the body. When men become sexually aroused, hormones, muscles, nerves, and blood vessels all work with one another to create an erection.
The main male sex organs are the penis and the testicles which produce semen and sperm, which, as part of sexual intercourse, fertilize an egg in the female’s body; the fertilized egg (zygote) develops into a fetus, which is later born as an infant.
Men can get women get pregnant in a variety of ways, but the most common way is through unprotected vaginal sex. During unprotected sex, when a man ejaculates sperm into the vagina. The sperm can then travel up through the cervix, into the uterus, and, if an egg is present, the sperm may fertilize it. This fertilized egg can implant in the womb and grow into a baby.
This is true. Men determine the sex of a baby depending on whether their sperm that fertilizes the woman’s egg is carrying an X or Y chromosome (gene). Women’s eggs only have X chromosome while Men have both X and Y chromosome sperms, so If an X chromosome sperm combines with the X chromosome in the woman’s egg, then it will make a baby girl (XX) while if a Y chromosome sperm combines with the X chromosome in the woman’s egg, then you would have make a boy (XY).
