The reproductive system overviewThe reproductive mechanism is a collection of organs and also a network the hormone production that work-related together to produce life.The masculine reproductive system contains the testes (which produce sperm), penis, epididymis, vas deferens, ejaculatory ducts and urethra.The woman reproductive system is composed of the ovaries (which produce eggs or oocytes), fallopian tubes, uterus, cervix, vagina and also vulva.

What go the reproductive device do?
The reproductive mechanism is a collection of organs and also a network the hormone production in men and women that enable a guy to impregnate a woman who provides birth come a child. During conception, a sperm cell from the male fuses v an egg cell in the woman, creating a fertilized egg (embryo) the implants and also grows in the uterus throughout pregnancy.
Abnormalities or damage to reproductive organs and malfunction of the hormone production and delivery mechanism that governs reproduction room common causes that infertility in men and also women.
How the brain works as component of the reproductive system
Brain centers play a key role in the regulation and control of the reproductive hormones and also system. Hormones are chemical messengers that impact the management of various other cells with receptors because that the hormone. Hormones might be produced in one component of the body and travel in the blood to another component of the human body to begin an action.
The reproductive mind centers are comprised of the hypothalamus, located in the central part of the brain, and also the pituitary gland, situated at the basic of the mind just below the hypothalamus. Additional higher mind regions influence activity in the hypothalamus.
The hypothalamus produce gonadotropin-releasing hormone (GnRH) to control the production and release the FSH (follicle-stimulating hormone) and also LH (luteinizing hormone) in the pituitary gland. FSH and LH space the 2 gonadotropic hormones connected in both male and female reproduction. The rate and magnitude that GnRH pulses from the hypothalamus control the release of FSH and LH from the pituitary gland.
Reproductive hormones in women
The menstrual bike is regulation by the complex interactions the hormones created in the hypothalamus, pituitary and also ovary. FSH exit from the pituitary stimulates the ovarian follicles to start maturation and also growth. Follicles room sac-like frameworks in the ovary include eggs. As the follicle and egg develops, cell within the follicle produce estrogen. Follicle cell produce an additional hormone referred to as inhibin the circulates earlier to the hypothalamus and pituitary come decrease the release of FSH.
The manufacturing of estrogen proceeds to rise under the affect of FSH as the follicle matures and also increases in size. When the follicle is mature, maximum manufacturing of estrogen occurs and also this signal a quick rise in LH native the pituitary gland.
LH, together with the estrogen developed by the ovaries, help in the maturation process of the egg. LH likewise triggers ovulation – the relax of a tires egg from among the follicles in the ovary. ~ ovulation, the follicle turns into a various structure, the corpus luteum, which produces progesterone.
Progesterone acts on the uterine lining (endometrium) leading to it to thicken in ready for implantation. Progesterone is crucial for implantation and also pregnancy. If implantation does no occur, the thickened endometrium will malfunction and be lost with expression bleeding.
Reproductive hormone in men
In men, FSH from the pituitary gland stimulates the testes to develop sperm by a procedure known together spermatogenesis. LH native the pituitary gland signal the testes to develop testosterone, which boosts sperm maturation. Testosterone is the major male sex hormone.
Key features & components of the woman reproductive system
The woman reproductive system is design to:Produce the eggs vital for reproduction, called the ova (ovum is singular for one egg) or oocytesIncubate and also nourish a fertilized egg until it is completely developedProduce woman sex hormone that preserve the reproductive cycle

Key attributes & components of the male reproductive system
The masculine reproductive system performs the complying with functions:Produces, maintains and also transports sperm (the masculine reproductive cells) and protective fluid (semen)Discharges sperm within the woman reproductive tract during sexProduces and also secretes male sex hormones responsible for maintaining the male reproductive system

Other glands — several glands create semen or liquid in assistance of the reproductive process. The seminal vesicle produces fructose that provides energy to the sperm as they look for an egg. The prostate gland also to produce a fluid that help the sperm move more quickly through the female reproductive system. Another collection of glands called bulbourethral, or sometimes Cowper’s glands, renders a fluid for protecting the sperm top top its way through the urethra.
