What is the reproductive system?
Introduction to the Reproductive System. The major function of the reproductive system is to ensure survival of the species. Other systems in the body, such as the endocrine and urinary systems, work continuously to maintain homeostasis for survival of the individual. An individual may live a long, healthy, and happy life without producing ...
What are the primary reproductive organs?
To produce hormones. These functions are divided between the primary and secondary, or accessory, reproductive organs. The primary reproductive organs, or gonads, consist of the ovaries and testes. These organs are responsible for producing the egg and sperm cells gametes), and hormones. These hormones function in the maturation ...
What is the reproductive system?
The reproductive system is a collection of organs and a network of hormone production that work together to create life. 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 are the reproductive cells?
Reproductive cells: The eggs and sperm are the reproductive cells. Each mature reproductive cell is haploid in that it has a single set of 23 chromosomes containing half the usual DNA amount. Except for the eggs and sperm, each cell in the human body -- there are 100 trillion cells in each of us -- contains the entire human genome, ...
Which cells are exceptions to the usual rules concerning chromosomes, genes, and DNA?
The reproductive cells -- the eggs and sperm -- are thus notable exceptions to the usual rules concerning chromosomes, genes, and DNA.
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 to get through your menstrual cycle?
The average menstrual cycle takes about 28 days and occurs in phases. These phases include:
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 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 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.
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.
Where do sperm fetuses discharge?
They discharge sperm into the female reproductive tract.
What is the function of sperm?
The function of the sperm is to provide half of the genetic material to form a fertilized zygote or embryo upon fertilizing with an egg. It also provides centrioles to allow centrosome and microtubules to form to allow genetic material from the two to combine.
What is a Sperm Cell?
A sperm cell is a form of gamete or reproductive cell found in the male human body. The word sperm is derived from the Greek word sperma, meaning seed. It is a haploid (meaning it contains 23 chromosomes), which is half of the genetic material required to form a fertilized zygote via sexual reproduction. The other half of the genetic material comes from the egg, which the sperm must fertilize to form a fertilized zygote. While an egg cell can only contain an X chromosome, the sperm cell can have either an X or Y chromosome. Thus, the DNA carried in the sperm cell (XX for female or XY for male) determines the sex of the fertilized zygote.
What are the structures of the midpiece of sperm?
The midpiece of a sperm contains three primary structures: a typical centriole, an atypical centriole, and a central core with multiple mitochondria wrapped around it. In normal cells, mitochondria are the cell's powerhouse that stores and provides the energy needed for all cellular processes. Similarly, in a sperm cell, these multiple mitochondria in the midpiece store and provide energy for the sperm to transport itself into the cervix, uterus, and fallopian tubes to search for and fertilize the female egg.
How are sperm cells formed?
Sperm cells are formed via a process known as spermatogenesis. This process takes place in the seminiferous tubules in the testes of the male body. Firstly, the spermatogonia will turn into spermatocytes. These spermatocytes are the cells that undergo the primary event known as meiosis. In meiosis I and II, a parent sperm cell replicates its genetic material, allows any cross-over of genetic material to occur, and divides the genetic material into two and then further into four total daughter sperm cells known as spermatids. The daughter sperm cells or spermatids each contain 23 chromosomes each. They do not undergo any further cell division and have a minimal life span.
How is fertility measured?
Male fertility is measured by a sperm's quantity and quality. The quality of sperm is further measured by its size and the age of the male. As a man gets older, there is a higher risk of genetic mutation in the DNA inside the sperm. Also, an older male typically produces sperms with less volume and slower motility. All of these factors impact the sperm's ability to fertilize an egg and lead to pregnancy. A healthy human sperm ranges from 40 to 50 micrometers in length and can only be seen under a microscope. Conversely, a healthy human egg is 30x larger and visible to the naked eye.
What are the three features of a sperm cell?
The three anatomical features of a sperm cell are: 1) the head, 2) the mid-piece and lastly 3) the tail or the flagellum. The head contains the genetic material and acrosome. The mid piece contains the mitochondria. And, the tail is used to transport the sperm within the female reproductive tract.
What is the head of a chromosome?
The head is the portion that contains the nucleus and the vacuoles. The nucleus includes 23 densely structured chromosomes. At the tip of the head is a flat structure known as an acrosome. An acrosome is a sac that contains enzymes needed to penetrate the outer layer of an egg upon fertilization.
