Male and female reproductive systems foster egg production and maturation, allowing humans to procreate, according to TeensHealth. Both systems produce gametes, or sex cells; the male gamete is sperm, which fertilizes the female gamete, or ovum. The fertilized ovum becomes a zygote and progresses through several states of physical development while inside a woman's uterus.Know More
The male reproductive system contains internal and external organs, including the testicles, penis, scrotum, urethra, seminal vesicles and prostate gland. The testicles are located inside the scrotum and produce sperm and testosterone hormones, according to WebMD. Testosterone drives the physical development of the male body during puberty, such as voice changes, enhanced muscle mass and facial hair growth. The epididymis and vas deferens are male ductal organs that carry matured sperm from the testes to the urethra. The prostrate gland releases fluid that mixes with sperm, and when men ejaculate, semen flows through the urethra to the penis and out of the body.
Female reproductive organs are entirely internal and mainly consist of the vagina, ovaries, uterus and fallopian tubes, according to TeensHealth. Eggs are nurtured in the ovaries and released into the fallopian tubes during ovulation. Sperm ejaculated into a woman's body may fertilize a matured egg, creating a zygote. The fertilized egg rests in the uterine lining and absorbs nutrients as it grows from an embryo to a human child. When the egg is not fertilized, the body ejects uterine blood and tissue matter during menstruation.Learn more about Reproductive Anatomy
A woman reaches reproductive maturity when she experiences her first menstruation, which includes the shedding of the inner-lining of the uterus. This first period occurs during puberty, and at this time, a woman's egg can be fertilized by sperm, and she can reproduce. In men, the first signs of reproductive maturity include enlargement of the testicles and penis, a surge in testosterone and the production of sperm, explains MedicineNet, Inc.Full Answer >
Ovaries store human gametes, or eggs, and produce hormones as girls mature and begin ovulating, according to Nemours. From birth, a female's ovaries are filled with unfertilized eggs. During adolescence, the pituitary gland in the brain releases hormones that trigger the production of sex hormones, such as estrogen, in the ovaries.Full Answer >
A female frog's reproduction system includes ovaries, oviducts and two uteruses. The ovaries produce eggs, the oviducts connect the frog's uteruses to her ovaries and the uteruses store the eggs until they are released during mating. A female frog does not raise her young inside herself during a gestation period.Full Answer >
In a large number of species, the reproductive system hosts organs and systems, such as gonads, needed for successful reproduction and also secretes sex hormones such as progesterone and testosterone, notes Wikipedia. In addition, the female of many species come with specialized structures for nourishing and protecting offspring until birth.Full Answer >
