Does alcohol affect my sperm morphology? Or does alcohol affect my sperm DNA? Or else does alcohol affect sperm during conception? Or does alcohol affect fertility when trying to conceive? Or even does alcohol affect sperm and birth defects? If you and your spouse are planning to have a baby and above such questions relating to alcohol, sperm and pregnancy are disturbing your mind. Then the following chapters on the effects of alcohol on male fertility will help you to clear all your doubts stated Dr.Sivakumar Chandrasekaran(Centre Head - Indira IVF Clinic in Chennai) while addressing the various queries held at a seminar addressing male fertility issues related to alcohol consumption at the Indira IVF centre in Chennai.
Chapter - 1
The male reproductive mechanism includes the hypothalamus, the anterior pituitary gland, as well as the testes. Alcoholic beverages may negatively affect the performance of every one of these parts, thereby inducing impotence, infertility, and also diminished male secondary sexual properties. In the testes, alcohol consumption may negatively influence the Leydig cells, which generate as well as emit the hormone testosterone. Scientific studies discovered that severe alcohol use leads to diminished testosterone quantities in the bloodstream. Alcoholic beverages additionally impair the performance of the testicular Sertoli cells that have a vital function in sperm maturation. In the pituitary gland, alcohol consumption may reduce the generation, discharge, and/or activities of 2 bodily hormones with crucial reproductive capabilities, luteinizing hormone as well as the follicle-stimulating hormone. Lastly, alcoholic beverages can negatively affect hormone generation in the hypothalamus explained Dr.Sivakumar Chandrasekaran(Centre Head - Indira Infertility Clinic and test tube baby centre in Chennai).
In both women and men, the sex hormones regulating reproduction create an elaborate as well as a carefully tuned process that influences every cellular process inside the body. The male reproductive process comprises of 3 parts:
1. A human brain area is known as the hypothalamus,
2. The anterior pituitary (a gland which is situated at the source of the human brain yet is not regarded as a brain location),
3. The testes.
At this point, we briefly review just how these 3 internal organs along with the hormones they generate interact to make sure as well as control male reproductive performance. The content then explains alcohol’s influence on each of the 3 internal organs, gaining on scientific studies in both equally human beings as well as animals. The discussion additionally addresses prospective treatments for averting or even reversing alcohol’s deleterious results informed Dr.Sivakumar Chandrasekaran(Centre Head - Indira IVF Clinic in Chennai).
Introduction of the Male Reproductive Process
The three areas in the reproductive system of an adult male, the hypothalamus, and the anterior pituitary gland, have purely regulatory capabilities, that are mediated by the human hormones released from both of these internal organs. The 3rd ingredient, the testes, in addition, creates vital hormones regulating male sexual features as well as behaviours, the most significant in which there is testosterone. Besides, the testes are completely responsible for sperm generation.
The hypothalamus, that is situated at the base of the human brain, is usually referred to as the master control unit of the reproductive mechanisms of both women and men. Among some other human hormones, the hypothalamus generates gonadotropin releasing hormone (GnRH). GnRH is released in pulses into a uniform system of blood vessels that join the hypothalamus to the anterior pituitary gland, that is situated simply beneath the hypothalamus.
Due to the GnRH stimulation, the anterior pituitary gland generates 2 hormones that regulate reproductive functions—luteinizing hormone (LH) as well as follicle-stimulating hormone (FSH) — and discharges these into the normal blood circulation. These two hormones have various capabilities in women and men. In adult males, LH will stimulate the testes to generate the hormone testosterone, while FSH has a significant role in sperm maturation described our IVF specialist in Chennai Dr.Sivakumar Chandrasekaran(Centre Head - Indira IVF Clinic in Chennai).
Additionally, the anterior pituitary gland generates the hormone prolactin. In adult males, increased prolactin amounts have a part in reproduction by ultimately controlling testosterone level within the body.The testes are comprised mainly of the seminiferous tubules, the place of sperm cell formation as well as maturation. Interspersed amongst those tubules are so called interstitial cells, which include a cell type known as Leydig cells, which generate the 'male' sex hormone testosterone. Along with the operation in reproduction, testosterone assists control numerous diversified body features, which includes bone as well as muscle building; red blood cell turnover; as well as growth in addition to sustenance of men sexual features, like sexual drive (i.e., sexual desire), development of skin as well as body hair, and even deepening the tone of voice throughout puberty explained our infertility specialist in Chennai Dr.Sivakumar Chandrasekaran(Centre Head - Indira IVF Centre in Chennai).
Accordingly, an insult to the hormonal process regulating testosterone generation may affect not just in infertility but will also in some other deleterious outcomes, like enhanced bone damage (i.e., osteoporosis), reduced muscle tissue functionality, and even less than standard levels of red blood cells (i.e., anaemia).
Another essential testicular cell form is the Sertoli cell. These types of body cells, that are embedded in the interior walls of the seminiferous tubules, perform an essential part in sperm growth by helping and replenishing the sperm cells throughout their maturation.
The 3 parts of the male reproductive system—the hypothalamus, anterior pituitary, as well as testes — develop a carefully tuned process known as the hypothalamic-pituitary-gonadal (HPG) axis, that is regulated by means of a traditional negative response system. Since testosterone amounts in the blood rise, the anterior pituitary turns into less receptive to stimulus by GnRH, leading to decreased LH as well as FSH secretion. Since LH leads to testosterone generation, lowered LH secretion leads to decreased testosterone amounts. Alternatively, in case testosterone quantities in the blood fall (e.g., due to a personal injury to the testes), the anterior pituitary’s sensitivity to GnRH improves and more LH, as well as FSH, are released, thus encouraging testosterone generation by the Leydig cells stated Dr.Sivakumar Chandrasekaran(Centre Head - Indira IVF Clinic in Chennai).
Certain scientific investigations recommend that testosterone also offers an adverse feedback function on GnRH. Besides this feedback loop, numerous hormones generated within as well as outside the testes manage testosterone development. One particular hormone which is developed within the testes (and in some other body parts, which includes the hypothalamus) is β-endorphin, a molecule just like morphine (i.e., an endogenous opioid3). β-Endorphin generated within the testes inhibits testicular testosterone generation and/or discharge. Moreover, β-endorphin discharged in the hypothalamus leads to reduced GnRH ranges. Reduced GnRH quantities, consequently, result in lowered LH as well as FSH secretion from the anterior pituitary as well as lowered testosterone generation by the Leydig cells mentioned Dr.Sivakumar Chandrasekaran(Centre Head - Indira IVF Centre in Chennai).

Alcohol’s Impact on the Testes
Many researchers have mentioned that hazardous drinking in adult males could damage testosterone generation as well as shrinkage of the testes (i.e., testicular atrophy). Those alterations may result in impotence, infertility, as well as lowered male secondary sexual features (e.g., decreased facial as well as chest hair, breasts enhancement, along with a change in body fat deposition from the tummy to the thigh region). For instance, in a typical research by Lloyd and Williams (1948), 72% of adult males with enhanced alcoholic cirrhosis have shown diminished sex drive and also sexual efficiency. In addition, Van Thiel as well as fellow workers (1974) pointed out that impotence was 'prominent in the most of the people, yet happened quite often among patients with higher liver damage'. Like a semi-quantitative level of the occurrence of impotence, those experts disclosed that of 22 males with cirrhosis, 18 males were not able to ejaculate for a semen evaluation (i.e., were impotent), two males generated absolutely no sperm whatsoever, one male experienced lowered sperm counts, and also just one male got a regular sperm count.
Testicular atrophy, in addition, seems to be typical among alcoholics, happening in as much as seventy-five percent of males with advanced alcoholic cirrhosis. This atrophy most likely is a result of numerous aspects, such as
(1) Alcohol’s detrimental influence on the testes;
(2) Alcohol’s influence on LH as well as FSH, which, among additional factors, activate testicular development; and also
(3) Numerous confounding elements, like malnutrition, concomitant therapy with numerous medicines, and also neglect of medicines apart from alcohol by the people. Testicular atrophy affects predominantly from the lack of sperm cells as well as reduced dimension of the seminiferous tubules.
Lastly, Lloyd and Williams (1948) revealed that 87% of males with enhanced alcoholic cirrhosis displayed reduced levels of axillary hair, whose growth depends upon testosterone as well as linked hormones.
Succeeding researchers have established alcohol’s deleterious influence on the testosterone-producing Leydig cells, the Sertoli cells, or even on the children of alcohol-ingesting men, unconnected of co-occurring liver ailment or even malnutrition stated Dr.Sivakumar Chandrasekaran(Centre Head - Indira IVF Clinic in Chennai).
