What is the difference between male and female reproductive systems?
The functional and most significant difference in the male and female reproductive system is that male reproductive system only produces sperms and delivers to the female reproductive system. On the other hand, the female reproductive system is designed to produce a baby and promote its development. Reproduction is the process of fusion of male and female gamete, to produce their species.
What is the definition of reproductive system?
reproductive system. The system of organs involved with the reproduction of an organism, especially sexual reproduction. In flowering plants, for example, the reproductive system consists of pistils and stamens. In mammals, it consists mainly of the ovaries, uterus, and vagina in females and the testes and penis in males.
Is the reproductive system the central nervous system?
The central nervous system is the brain and spinal cord. It controls the sex organ known as the penis . It does this through the use of chemical nerve signals called neurotransmitters .
What are the main parts and functions of the male and female reproductive systems?
Key Points The testes in the scrotum produce the male gamete, sperm, which is ejaculated in seminal fluid by the penis. The female reproductive system primarily consists of internal organs. The female gamete, ovum, is produced in the ovaries and is released monthly to travel to the uterus via the Fallopian tubes.
What are the functions of the parts of the male reproductive system?
The male reproductive system includes a group of organs that make up a man's reproductive and urinary system. These organs do the following jobs within your body: They produce, maintain and transport sperm (the male reproductive cells) and semen (the protective fluid around sperm).

The average menstrual cycle takes about 28 days and occurs in phases. These phases include: The follicular phase (development of the egg) The ovulatory phase (release of the egg) The luteal phase (hormone levels decrease if the egg does not implant)
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 are the internal organs of the male reproductive system?

The primary hormones involved in the functioning of the male reproductive system are follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone. FSH and LH are produced by the pituitary gland.
What is the function of the epididymis?
The epididymis is a long, coiled tube that rests on the backside of each testicle. It carries and stores sperm cells that are created in the testes. It’s also the job of the epididymis to bring the sperm to maturity — the sperm that emerge from the testes are immature and incapable of fertilization.
What is the role of LH in sperm production?
FSH is necessary for sperm production (spermatogenesis). LH stimulates the production of testosterone, which is necessary to continue the process of spermatogenesis. Testosterone is also important in the development of male characteristics, including muscle mass and strength, fat distribution, bone mass and sex drive.
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.
What is the function of the scrotum?
The scrotum protects your testes, as well as providing a sort of climate control system. For normal sperm development, the testes must be at a temperature slightly cooler than the body temperature.

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 process of oogenesis?
This asymmetrical cytokinesis results in one large egg cell (oocyte) and smaller cells called polar bodies. The polar bodies degrade and are not fertilized. After meiosis I is complete, the egg cell is called a secondary oocyte. The haploid secondary oocyte will only complete the second meiotic stage if it encounters a sperm cell. Once fertilization is initiated, the secondary oocyte completes meiosis II and becomes an ovum. The ovum fuses with the sperm cell and fertilization completes while embryonic development begins. A fertilized ovum is called a zygote.
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.
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.

What happens to the ovaries when you are born?
When you’re born, your ovaries contain all the eggs you’ll release throughout your lifetime. Once a month, a mature egg is released from the ovaries in a process called ovulation. The ovaries also produce a variety of female sex hormones, which are important for regulating a woman’s cycle and pregnancy.
What hormones are involved in the lining of the uterus during pregnancy?
For example, during a woman’s cycle, increases in the hormones estrogen and progesterone cause the lining of the uterus to thicken. This helps to prepare the uterus to receive and nurture a fertilized egg during pregnancy. If no fertilization occurs, the egg begins to break down.

How Many Eggs Does A Woman have?
- During fetal life, there are about 6 million to 7 million eggs. From this time, no new eggs are produced. At birth, there are approximately 1 million eggs; and by the time of puberty, only about 300,000 remain. Of these, only 300 to 400 will be ovulated during a woman's reproductive lifetime. Fertility can drop as a woman ages due to decreasing number and quality of the remaining eggs.
