Age brings about changes to the male and female reproductive systems that lead to loss of fertility and the physical and psychological symptoms of the menopause and andropause. In men and in women, middle age brings about changes to the reproductive system that eventually lead to infertility — although men stay fertile for longer. These changes are partly due to dramatic fluctuations in the production of sex hormones such as oestrogen, progesterone and testosterone.

Anatomy and Physiology of the Female Reproductive System

The reproductive system of an organism, also known as the genital system , is the biological system made up of all the anatomical organs involved in sexual reproduction. Many non-living substances such as fluids, hormones , and pheromones are also important accessories to the reproductive system. These differences allow for a combination of genetic material between two individuals, which allows for the possibility of greater genetic fitness of the offspring. 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.

Understanding the anatomy and physiology of the cow's reproductive system is fundamental to good cattle management. Basic knowledge in this area will help producers do a better job of getting cows rebred, especially when using artificial insemination and estrus synchronization. It will also enable producers to better understand and control reproductive diseases and calving problems. The ovary is the primary female reproductive organ and has two important functions: producing the female reproductive cell the egg or ovum and producing the hormones estrogen and progesterone. The cow's two ovaries are oval to bean-shaped organs that are 1—1.

NCBI Bookshelf. Sarao 3. The reproductive system in females is responsible for producing gametes called eggs or ova , certain sex hormones, and maintaining fertilized eggs as they develop into a mature fetus and become ready for delivery. During this period, cyclical expulsion of ova from the ovary occurs, with the potential to become fertilized by male gametes sperm. This cyclic expulsion of eggs is a normal part of the menstrual cycle. Female gametes derive from germ cells. In utero, oogonia rapidly divide until approximately 7 million germ cells form by the 7th month of gestation.

27.1: Anatomy and Physiology of the Male Reproductive System

The female reproductive system functions to produce gametes and reproductive hormones, just like the male reproductive system; however, it also has the additional task of supporting the developing fetus and delivering it to the outside world. Unlike its male counterpart, the female reproductive system is located primarily inside the pelvic cavity. Recall that the ovaries are the female gonads. The gamete they produce is called an oocyte.

 Умно, - сказала Сьюзан. Стратмор продолжал: - Несколько раз Танкадо публично называл имя своего партнера. North Dakota. Северная Дакота.
