explain male reproductive organs
Answers
Answer:
The male reproductive system includes the scrotum, testes, spermatic ducts, sex glands, and penis. These organs work together to produce sperm, the male gamete, and the other components of semen.
Answer:
The male reproductive system consists of two major parts: the testes, where sperm are produced, and the penis, according to Merck Manuals. The penis and urethra belong to both the urinary and reproductive systems in males. The testes are carried in an external pouch known as the scrotum, where they normally remain slightly cooler than body temperature to facilitate sperm production.
The external structures of the female reproductive system include the clitoris, labia minora, labia majora and Bartholin's glands, according to the Cleveland Clinic. The major internal organs of the female reproductive system include the vagina and uterus — which act as the receptacle for semen — and the ovaries, which produce the female's ova. The vagina is attached to the uterus through the cervix, while the fallopian tubes connect the uterus to the ovaries. In response to hormonal changes, one ovum, or egg — or more in the case of multiple births — is released and sent down the fallopian tube during ovulation. If not fertilized, this egg is eliminated during menstruation.
Fertilization occurs if a sperm enters the fallopian tube and burrows into the egg. While the fertilization usually occurs in the oviducts, it can also happen in the uterus itself. The egg then becomes implanted in the lining of the uterus, where it begins the processes of embryogenesis (in which the embryo forms) and morphogenesis (in which the fetus begins to take shape). When the fetus is mature enough to survive outside of the womb, the cervix dilates, and contractions of the uterus propel it through the birth canal.
Variations in the reproductive system
Around 49.5 percent of the world's population is female, so there are slightly more men on the planet than women, according to World Bank. A person's sex is determined by what reproductive system the person has, but it isn't always so simple. Some humans are born with parts of both male and female reproductive systems or incomplete reproductive organs of one sex or the other. Those with both male and female reproductive parts are considered intersex. Sometimes children are labeled as male or female, depending on how complete or functional one sexual reproductive system is over the other. Then, the other organs are removed.
Today, many parents are opting to leave both sets of reproductive organs intact with the intent of letting the child decide to keep or remove the various parts when they are older. A baby is born atypical genitalia in one in about 1,500 to 2,000 births, according to Intersex Society of North America.
Females that are born without all of their reproductive system are labeled as having Mayer Rokitansky Kuster Hauser Syndrome. This occurs in one in 5,000 female births, according to the Center for Young Women’s Health.
Diseases of the female reproductive system
Many parts of the male and female reproductive systems can be affected by cancer. In females, cancer can attack the uterus, ovaries, breast and cervix, among other organs, according to the American Cancer Society.
Many experts have seen what they refer to as the "Angelina Jolie" effect, where women are taking proactive measures by having breasts and internal reproductive organs removed if they have a family history of cancer before there are signs of the disease. "With better genetic testing and screening, we have seen a number of women who are being more proactive about their reproductive health," said Dr. Shana Wingo, who specializes on gynecologic oncology at Arizona Oncology.
