Human Reproductive System
The survival of the human population is maintained by reproduction.
In order for sexual reproduction to occur, a woman’s ovaries produce ova (eggs) and a man’s testes produce sperm.
After an egg has been fertilized by a sperm, it grows inside the
woman’s uterus to produce a new human being.
At conception, a female egg, or ovum, is fertilized by a male sperm.
The DNA in the head of the sperm enters the ovum, to be combined with the DNA in the nucleus of the ovum.
Ovum and Sperm
Each consists of a single cell, although the egg is much larger than the sperm.
Women's Reproductive Organs
Uterus
The uterus is an expandable, muscular sac that protects and nourishes developing offspring.
Fallopian tubes bring the ovum to the uterus and sperm to the ovum; this is where fertilization usually occurs
Ovaries contain the ova, one of which is released during each menstrual cycle; they also produce hormones.
Cervix
Cervix is the mouth of the uterus; also produces mucus to assist in
fertilization.
Vagina
The vagina is the passage from the uterus through which childbirth occurs; menstrual blood is discharged through the vagina; copulation occurs when the penis enters the vagina
The Menstrual Cycle
Between the ages of about 12 and 50, a woman produces one ripe ovum about every 24-30 days.
The ova are all present in the ovaries at birth, but they are not ready
to be released.
When one ova is almost ready, the lining of the uterus has also thickened in order to get ready to nourish a fertilized ovum.
Ovulation:
the ova are released, to go into the fallopian tube, where it may be fertilized by a sperm.
In case fertilization does not occur, the lining is shed (menstrual
bleeding).
Male Reproductive System
Men produce sperm in their testes.
During sexual stimulation, sperm travel through the vas deferens and are added to the fluids produced by the prostate gland and seminal vesicles, to make semen.
Semen is ejaculated through the erect penis into the woman’s vagina in order to fertilize an ovum.
Seminal vesicles produce a seminal fluid
Penis
the male organ for urination and copulation; its spongy tissue fills with blood to make it erect so that it can be inserted into the vagina to deposit semen
Prostate gland produces a seminal fluid.
Testis produces sperm
Scrotum
the sac that holds the testes outside of the abdomen, to keep them cool, as required for sperm production.
