The male reproductive system consists of a number of sex organs that play a role in the process of human reproduction.

NCBI Bookshelf. The male reproductive system consists of the internal structures: the testes, epididymis, vas deferens, prostate, and the external structures: the scrotum and penis. Testosterone can be converted in the periphery to a more active form, dihydrotestosterone via 5-alpha-reductase, or estradiol via aromatase. Other key hormones include inhibin B and Mullerian inhibiting substance MIS hormone, both produced by the Sertoli cells in the testes. Important hormones that modulate these include follicle-stimulating hormone FSH and luteinizing hormone LH , which are released from the anterior pituitary gland and are regulated by gonadotropin-releasing hormone GnRH , produced by the hypothalamus.

Anatomy and Physiology of the Female Reproductive System

Advanced Practice in Endocrinology Nursing pp Cite as. At birth, a female baby already has her lifetime supply of oocytes that will be released through ovulation when she is sexually matured, between menarche and menopause. Puberty initially starts with thelarche breast budding around the age of 11 and menarche usually starts at an average age of around The menopause is the end of menstrual cycles. Puberty, menstrual cycles, and establishment of pregnancy are controlled by the hypothalamic, pituitary, and ovarian hormones. Following the menopause, the ovaries are no longer able to produce enough oestrogen and ovarian failure results in a rise in the gonadotropins.

Male reproductive system

In the decade since the publication of the last edition, the study of reproductive physiology has undergone monumental changes. Chief among these advances are in the areas of stem cell development, signaling pathways, the role of inflammation in the regulatory processes in the various tissues, and the integration of new animal models which have led to a greater understanding of human disease. The new edition synthesizes all of this new information at the molecular, cellular, and organismal levels of organization and present modern physiology a more understandable and comparative context.

Trace the path of an oocyte from ovary to fertilization. The female reproductive system functions to produce gametes and reproductive hormones.

If you create an account, you can set up a personal learning profile on the site. Applied anatomy and physiology for basic obstetric care is an entry to your studies in this Module and the next four Modules, and is essential preparation for your practical skills training. Obstetric care refers to healthcare for women during pregnancy, labour and delivery, and their immediate postnatal care. It requires a good understanding of the anatomy and physiology of the female reproductive system. Anatomy is the study of the structures of the human body, i.

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 Figure Recall that the ovaries are the female gonads. The gamete they produce is called an oocyte. The external female reproductive structures are referred to collectively as the vulva Figure

Antenatal Care Module: 3. Anatomy and Physiology of the Female Reproductive System

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.

The female reproductive system consists of the paired ovaries and oviducts or uterine tubes , the uterus, the vagina, and the external genitalia Figure 22—1. This system produces the female gametes oocytes , provides the environment for fertilization, and holds the embryo during its complete development through the fetal stage until birth. As with male gonads, the ovaries produce steroidal sex hormones that control organs of the reproductive system and influence other organs.

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. In the perimenopause and menopause, most women experience physical and psychological symptoms that can be extremely disruptive. Although less dramatic, the changes prompted in men by the andropause can lead to erectile dysfunction and a loss of libido.

Стратмор вздохнул. - Оставь эти штучки детям, Грег. Отпусти .

Она попыталась собраться с мыслями, но они упрямо возвращали ее к. Дэвид Беккер. Единственный мужчина, которого она любила.

Такие же звезды, наверное, видит сейчас Дэвид в небе над Севильей, подумала. Подойдя к тяжелой стеклянной двери, Стратмор еле слышно чертыхнулся. Кнопочная панель Третьего узла погасла, двери были закрыты.
