Development of the reproductive organs

Human reproductive system , organ system by which humans reproduce and bear live offspring. Provided all organs are present, normally constructed, and functioning properly, the essential features of human reproduction are 1 liberation of an ovum , or egg , at a specific time in the reproductive cycle, 2 internal fertilization of the ovum by spermatozoa, or sperm cells, 3 transport of the fertilized ovum to the uterus , or womb, 4 implantation of the blastocyst, the early embryo developed from the fertilized ovum, in the wall of the uterus, 5 formation of a placenta and maintenance of the unborn child during the entire period of gestation , 6 birth of the child and expulsion of the placenta, and 7 suckling and care of the child, with an eventual return of the maternal organs to virtually their original state. For this biological process to be carried out, certain organs and structures are required in both the male and the female.

This can be seen in our closest relatives, the bonobo chimpanzees, who have sex for a wide variety of reasons including pleasure, bonding, and alleviating tension in addition to producing offspring. The reproductive system or genital system is a set of organs within an organism that work together to produce offspring.

These parts are internal; the vagina meets the external organs at the vulva, which includes the labia, clitoris, and urethra. The vagina is attached to the uterus through the cervix, while the uterus is attached to the ovaries via the fallopian tubes. At certain intervals, the ovaries release an ovum, which passes through the fallopian tube into the uterus. If, in this transit, it meets with sperm, the sperm penetrates and merges with the egg, fertilizing it.

The male reproductive system includes the penis, scrotum, testes, epididymis, vas deferens, prostate, and seminal vesicles. The penis and the urethra are part of the urinary and reproductive systems. The scrotum, testes testicles , epididymis, vas deferens, seminal vesicles, and prostate comprise the rest of the reproductive system. The penis consists of the root which is attached to the lower abdominal structures and pelvic bones , the visible part of the shaft, and the glans penis the cone-shaped end. The opening of the urethra the channel that transports semen and urine is located at the tip of the glans penis. The base of the glans penis is called the corona. In uncircumcised males, the foreskin prepuce extends from the corona to cover the glans penis.
