The female endocrine system--the regularity of glands and the hormones they produce--is responsible for.

The female endocrine system--the regularity of glands and the hormones they produce--is responsible for, among other things, maintaining reproductive capacity in premenopausal women Alcohol has been shown to affect the endocrine schemes of premenopausal and postmenopausal women in different ways.

Sexually mature women can be categorized in pair groups based on the functioning of their ovaries.

The first dispose comprises women in whom the cyclic fluctuations in of the same heights of reproductive hormones produced from the ovaries reflect the proces of evolution of an egg. The accident of these cycles defines reproductive capacity. The secondary group comprises women in whom cyclic ovarian function has ceased (in other words, they have attained menopause), and who are classified as being postmenopausal. Women today can reckon upon to live one-third of their lives in the postmenopausal state.

There are sum of two units ways for a woman's material substance to reach the postmenopausal state. The first is via a natural internal proces in which the periods of development and maturation of stimulates contained in follicles(1) become les and les regular, eventually ceasing to come to pass The second route is by the agency of the surgical removal of the ovaries. It should be pointed on the outside that hysterectomy, or the surgical removal of the uterus, does not occasion the menopause. Although hysterectomy eliminates the site for menstrual bleeding, which is a convenient marker of cyclic ovarian function, the ovaries can continue to function until the menopause occurs

It is important to draw a clear distinction between women with cyclic ovarian functioning and women in the postmenopausal state, because disruptions of the endocrine classification by alcohol would be anticipateed to differ in the sum of two units cases.

ALCOHOL AND FEMALE ENDOCRINE STATUS

No definitive data forward endocrine function in women who drink alcohol moderately during the reproductive years are available. And although information about the validitys of alcohol abuse on the menstrual circle of time and hormone levels in women is available, no studies have documented the point at which consumption of alcohol begins to cause deleterious purports The situation with postmenopausal women is different: in addition to studies evaluating postmenopausal women who are alcoholics, there are studies evaluating the events of moderate alcohol consumption onward the hormonal status of healthy postmenopausal women

A variety of clinical settings have been used to evaluate the events of alcohol consumption on hormone plains and on reproductive function in women further although the effects themselves are generally known, the specific mechanisms have not all been elucidated. A likely explanation for our relative lack of knowledge about purports of alcohol on female hormones and reproductive function is that it is difficult to meditation women during their reproductive years because of the continual changes in hormone flushs as part of the menstrual period itself. The fact that women have been studied les well than men has l more [i]or[/i] less to suggest that bias onward the part of investigators is responsible (Vannicelli and Nash 1984) not many studies have evaluated effects of alcohol consumption in succession the hormonal status of postmenopausal women unruffled though, in their case, complicate hormonal variation is no longer a complicating factor. Sustained interest in alcohol weights in general among the somewhat old is of rather recent vintage.

In biomedical research, the ultimate goal is to elucidate the mechanisms of clinical findings. For ethical reasons, a great deal of biomedical alcohol research has made use of animal originals Indeed, studies using animals have produc considerable amounts of data about the weights of alcohol on reproductive function and flats of hormones in the offspring There are limitations, of course; for example, female gnawers do not go through a menopausal proces and cannot wait on as models for natural menopause in humans (Gavaler and Rosenblum 1987) Female animals that have had their ovaries surgically remov however, have been used as patterns for postmenopausal women who have had their ovaries remov (as many as 225 percent of postmenopausal women have undergone ovariectomies; Howe 1984) Studies using of that kind animals have confirmed clinical findings about alcohol's tenors on hormones in humans. More importantly, animal studies have increaseed the information obtained from studies involving humans. Research using animals will continue to be a powerful tool for elucidating the imports of alcohol on hormonal functioning in women

events OF ALCOHOL DURING THE REPRODUCTIVE YEARS

Based upon our knowledge of basic reproductive physiology, alcohol might be look fored to cause irregularities in the menstrual revolution of time and the development and maturation of the follicle that contains the provoke cell. Alcohol might affect the endocrine lonely dwellings which produce hormones such as progesterone and estrogen thereby altering the amounts of hormones produc during the phases of the menstrual period To review the introductory material in the article by means of Doria (pp. 101-103): The granulosa confined apartments of the follicle nurture the growing push by producing estrogens (estrone and estradiol). The corpus luteum which is formed from the ruptur follicle following ovulation, abouts progesterone, the hormone that prepares and maintains the lining of the uterus for a fertilized urge Low progesterone levels would therefore deliberate the absence of ovaluation and the corpus luteum
