The male reproductive system includes the testes (which produce sperm), penis, epididymis, vas deferens, ejaculatory ducts and urethra. The female reproductive system consists of the ovaries (which produce eggs or oocytes), ...
Which organ is responsible for sperm production?
Testicles (testes) — The testes (oval organs that lie in the scrotum) are the primary male reproductive organ and are responsible for testosterone and sperm production. Epididymis — The epididymis is a C-shaped tube that rests on the backside of each testicle.
What happens to the sperm during conception?
During conception, a sperm cell from the man fuses with an egg cell in the woman, creating a fertilized egg (embryo) that implants and grows in the uterus during pregnancy. Abnormalities or damage to reproductive organs and malfunction of the hormone production and delivery system that governs reproduction are common causes ...
Which hormone stimulates the testes to produce sperm?
In men, FSH from the pituitary gland stimulates the testes to produce sperm by a process known as spermatogenesis. LH from the pituitary gland signals the testes to produce testosterone, which enhances sperm maturation. Testosterone is the primary male sex hormone.
What is the function of follicles?
Follicles are sac-like structures in the ovary containing eggs. As the follicle and egg develops, cells within the follicle produce estrogen . Follicle cells produce another hormone called inhibin that circulates back to the hypothalamus and pituitary to decrease the release of FSH.
Which brain region regulates the production and release of FSH and LH?
Additional higher brain regions influence activity in the hypothalamus. The hypothalamus produces gonadotropin-releasing hormone (GnRH) to regulate the production and release of FSH (follicle-stimulating hormone) and LH (luteinizing hormone) in the pituitary gland.
What is the function of the follicles in the menstrual cycle?
The menstrual cycle is regulated by the complex interactions of hormones produced in the hypothalamus, pituitary and ovary. FSH released from the pituitary stimulates the ovarian follicles to begin maturation and growth. Follicles are sac-like structures in the ovary containing eggs.
What is the function of the female reproductive system?
The female reproductive system has two functions: The first is to produce egg cells, and the second is to protect and nourish the offspring until birth. The male reproductive system has one function, and it is to produce and deposit sperm. Humans have a high level of sexual differentiation.
What are the organs of the reproductive system?
In mammals, the major organs of the reproductive system include the external genitalia (penis and vulva) as well as a number of internal organs, including the gamete -producing gonads (testicles and ovaries). Diseases of the human reproductive system are very common and widespread, particularly communicable sexually transmitted diseases.
What is the breeding system of a plant?
The breeding system, or how the sperm from one plant fertilizes the ovum of another, depends on the reproductive morphology, and is the single most important determinant of the genetic structure of nonclonal plant populations.
How long does it take for sperm to get into the uterus?
Upon successful fertilization and implantation, gestation of the fetus then occurs within the female's uterus for approximately nine months, this process is known as pregnancy in humans.
What are the reproductive structures of angiosperms?
Among all living organisms, flowers , which are the reproductive structures of angiosperms, are the most varied physically and show a correspondingly great diversity in methods of reproduction. Plants that are not flowering plants ( green algae, mosses, liverworts, hornworts, ferns and gymnosperms such as conifers) also have complex interplays between morphological adaptation and environmental factors in their sexual reproduction. The breeding system, or how the sperm from one plant fertilizes the ovum of another, depends on the reproductive morphology, and is the single most important determinant of the genetic structure of nonclonal plant populations. Christian Konrad Sprengel (1793) studied the reproduction of flowering plants and for the first time it was understood that the pollination process involved both biotic and abiotic interactions.
What are the three reproductive organs?
The major reproductive organs of the male can be grouped into three categories. The first category is sperm production and storage. Production takes place in the testes which are housed in the temperature regulating scrotum, immature sperm then travel to the epididymis for development and storage.
How many vaginae do marsupials have?
The reproductive system of marsupials is unique in that the female has two vaginae, both of which open externally through one orifice but lead to different compartments within the uterus; males usually have a two-pronged penis, which corresponds to the females' two vaginae.
What is the male reproductive system?
What’s the male reproductive system? The male reproductive system includes a group of organs that make up a man’s reproductive and urinary system.
What are the main hormones that regulate the reproductive system?
The primary hormones involved in the functioning of the male reproductive system are follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone.
What are the internal organs of the male reproductive system?
These external organs include the penis, scrotum and testicles. Internal organs include the vas deferens, prostate and urethra. The male reproductive system is responsible for sexual function, as well as urination. Urology 216.444.5600.
How many testes do men have?
Most men have two testes. The testes are responsible for making testosterone, the primary male sex hormone, and for producing sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubules are responsible for producing the sperm cells through a process called spermatogenesis.
Which gland is responsible for ejaculation?
The fluid of the seminal vesicles makes up most of the volume of your ejaculatory fluid, or ejaculate. Prostate gland: The prostate gland is a walnut-sized structure that’s located below the urinary bladder in front of the rectum. The prostate g land contributes additional fluid to the ejaculate.
What is the glans?
The glans: This is the cone-shaped end of the penis. The glans, which is also called the head of the penis, is covered with a loose layer of skin called foreskin. This skin is sometimes removed in a procedure called circumcision.
Where do sperm fetuses discharge?
They discharge sperm into the female reproductive tract.
What is the function of external female reproductive structures?
The function of the external female reproductive structures (the genital) is twofold: To enable sperm to enter the body and to protect the internal genital organs from infectious organisms.
What are the internal organs of the reproductive system?
The internal reproductive organs include: Vagina: The vagina is a canal that joins the cervix (the lower part of uterus) to the outside of the body. It also is known as the birth canal. Uterus (womb): The uterus is a hollow, pear-shaped organ that is the home to a developing fetus.
What happens to the uterus after implantation?
Once in the uterus, the fertilized egg can implant into thickened uterine lining and continue to develop. If implantation does not take place, the uterine lining is shed as menstrual flow. In addition, the female reproductive system produces female sex hormones that maintain the reproductive cycle. During menopause, the female reproductive system ...
Where do oocytes go in the reproductive cycle?
The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle.
How does the egg get released?
As the egg is released (a process called ovulation) it is captured by finger-like projections on the end of the fallopian tubes (fimbriae). The fimbriae sweep the egg into the tube. For one to five days prior to ovulation, many women will notice an increase in egg white cervical mucus.
What happens to the female reproductive system during menopause?
During menopause, the female reproductive system gradually stops making the female hormones necessary for the reproductive cycle to work. At this point, menstrual cycles can become irregular and eventually stop. One year after menstrual cycles stop, the woman is considered to be menopausal. Cleveland Clinic is a non-profit academic medical center.
How long does it take for a woman to have a period?
Most women will have a menstrual period 10 to 16 days after ovulation. During this phase, the following events occur: The rise in estrogen from the dominant follicle triggers a surge in the amount of luteinizing hormone that is produced by the brain. This causes the dominant follicle to release its egg from the ovary.
What are the reproductive systems?
The reproductive system is susceptible to a number of diseases and disorders. These are of varying degrees of detriment to the body. This includes cancer that can develop in reproductive organs such as the uterus, ovaries, testicles, and prostate.
What is the function of the reproductive system in 2021?
The human reproductive system and the ability to reproduce make life possible. In sexual reproduction, two individuals produce offspring that have some of the genetic characteristics of both parents. The primary function of the human reproductive system is to produce sex cells.
What are the internal and external reproductive organs?
The female reproductive system is comprised of both internal and external reproductive organs that both enable fertilization and support embryonic development. Structures of the female reproductive system include: Labia majora: Larger lip-like external structures that cover and protect other reproductive structures.
What are the internal and external structures of the reproductive system?
The primary reproductive organs of either system are called gonads (ovaries and testes) and these are responsible for gamete (sperm and egg cell) and hormone production. Other reproductive structures and organs are considered secondary reproductive structures and they aid in the growth and maturation of gametes and offspring.
What is the function of the epididymis?
Epididymis: System of ducts that receive immature sperm from the testes. The epididymis functions to develop immature sperm and house mature sperm.
How are gametes produced?
Gametes are produced by a two-part cell division process called meiosis. Through a sequence of steps, replicated DNA in a parent cell is distributed among four daughter cells. Meiosis produces gametes that are considered haploid because they have half the number of chromosomes as the parent cell.
What is the process of producing sperm cells?
Spermatogenesis. The production of sperm cells is known as spermatogenesis . Stem cells develop into mature sperm cells by first dividing mitotically to produce identical copies of themselves and then meiotically to create unique daughter cells called spermatids.
