Does masturbation cause hair loss? Facts and myths

dht and hair loss relationship

This myth that masturbation causes hair loss may come from theories the levels of a hormone linked to hair loss, called DHT (dihydrotestosterone). or other aspects of an individual's life; cause problems in a relationship. Number of DHT receptors on the hair follicles increases in balding scalp, . there is an appreciable relation between the shape of the cranium and the hair loss. Women's hair loss shares many of the same causes as men's hair loss, DHT, a derivative of the male hormone testosterone, is the enemy of.

Clinically observed hair loss is due to the continuous miniaturization of affected hair follicles. Genetic factors and androgenic factors especially dihydrotestosterone DHTwhich is a testosterone tissue metabolite, play major roles in the pathogenesis of AGA.

However, expert opinions about the usefulness of DHT in the diagnosis of this type of alopecia are divided.

Aim To evaluate the usefulness of DHT level in patients with androgenetic alopecia compared with the control group. Material and methods The study comprised 49 subjects: The control group consisted of 17 healthy women and 4 men without hair loss. Results Increased serum concentrations of DHT were observed in patients with androgenetic alopecia 17 women, 5 menbut also in the control group. The differences in mean values of DHT were not significant according to the types of alopecia and the control group.

Increased serum concentrations of DHT were not correlated with the advance of alopecia. Conclusions Dihydrotestosterone is the most influential androgen and seems to play a very important role in the pathogenesis of androgenetic alopecia. Based on the results of our study and others, the most important factors would appear to be the genetically-determined sensitivity of the follicles to DHT and their different reactions to androgen concentration.

The hair follicle from which the hair grows is influenced by endogenous and exogenous factors. The hair cycle within the human scalp is asynchronous: In the development cycle of the hair follicle, there are three phases: The life cycle of the hair follicle can be compromised in any of its phases. In the human life, the hair follicle passes hair cycle probably on average 20—30 times [ 1 — 3 ].

Hair loss is a physiological process.

Daily loss should not exceed 70— hairs, but individual variations may exist and increased hair loss is seen in autumn and spring [ 4 ]. However, a problem occurs when hair loss exceeds per day and lasts longer than a few weeks.

The Connection Between Hormones and Hair Loss (and How to Stop Thinning Hair)

The clinical picture of diseases of the scalp is varied, and the type of hair loss depends on factors that play a role in its pathogenesis. Alopecia can be divided into non-scarring and scarring forms. Non-scarring alopecia, unlike scarring alopecia, leads to hair loss without destroying hair follicles. The most common types of non-scarring hair loss are male and female androgenetic alopecia, telogen effluvium and alopecia areata. This group includes also some less common variations: Androgens are known to be associated with the mechanisms of hair growth and renewal.

The hair follicle is the site of androgen-tissue interaction, and is also the peripheral organ for the synthesis of substantial amounts of androgens from cholesterol [ 56 ].

DHT (dihydrotestosterone): What is DHT's role in baldness?

Androgens Androgens are hormones synthesized from cholesterol. Under physiological conditions, they are present in both sexes, but their concentration is higher in men. In women, androgens are precursors of female sex hormones and are converted to estrogens.

Androgens can be classified based on the site of production: Androgen receptors are present in almost all organs, which then are influenced by the hormones in both men and women [ 7 ]. Secondary sexual features are formed in the uterus, spermatogenesis occurs and muscle mass develops under the influence of androgens.

They also have a significant impact on the development and function of the sebaceous glands, and the functioning of the pilosebaceous unit [ 8 ]. The response of hair follicles to androgens varies according to body area. More than types of androgenic activity in cells have been reported [ 9 ]. The presence of high levels of sex hormones is known as hyperandrogenism. Most often, this is a consequence of excessive production of endogenous hormones by dysregulation of the hypothalamic-pituitary-adrenal cortex, polycystic ovary syndrome PCOS or by hormonally-active tumors.

Less frequently it arises as a result of exogenous hormone delivery into the body by doping or iatrogenic causes. Hyperandrogenism in women is associated with characteristic features such as formation of a male body type, change in voice tone, the appearance of the male pattern hair, impaired fertility, clitoromegaly, breast atrophy and androgenetic alopecia, while in men, elevated androgen levels usually lead to androgenic alopecia.

However, in both sexes, severe seborrhea and acne vulgaris may appear [ 10 ].

Dihydrotestosterone Dihydrotestosterone is a tissue metabolite of testosterone. Dihydrotestosterone has the ability to bind to sex hormone binding globulin SHBG more than three times higher than testosterone.

Determination of DHT concentration is helpful for antiandrogen therapy in patients with prostate cancer or androgenetic alopecia [ 17 ]. Androgenetic alopecia Androgenetic alopecia concerns both men and women.

Male androgenetic alopecia MAGA is the most common form of hair loss that occurs in men. It can begin at different stages of life, but its incidence increases with the patient's age. Female androgenetic alopecia FAGA is one of the most common forms of hair loss in women. The precise etiology and pathogenesis of androgenetic alopecia is still unclear, but genetic and androgenic factors play definite roles.

However, it is probably an autosomal dominant [ 23 ] with variable gene penetrance and multigenic effects dependent on many factors [ 2425 ]. The probability of MAGA depends on the number of first and second degree relatives who have experienced this type of alopecia. An unfavorable prognostic factor is the presence of androgenetic alopecia AGA in the patient's mother or sisters [ 3 ].

Everything you need to know about DHT

Other studies suggest that genetic variants present in or near the gene encoding the androgen receptor AR chromosome Xq12 may have an impact on the occurrence of MAGA [ 27 — 29 ]. InProdi et al. Although studies suggesting a relationship between MAGA and chromosome X may confirm the impact of genetic factors inherited from the mother, these results do not explain the observed inheritance of MAGA from the father.

Also inHillmer et al. Men diagnosed with the newly-discovered variant and the other susceptibility locus for the androgen receptor are seven times more likely to experience alopecia. Their presence is dependent on latitude, which explains the ethnic variation of MAGA. However, their role in hair loss is still not fully understood. Other studies based on genome mapping indicate a relationship between MAGA and chromosome 3q26 [ 33 ]. Also, the inheritance of female androgenic alopecia FAGA is not fully understood.

It may well be of an autosomal dominant nature, with either variable expression of genes or polygenic effects. The wide variation in phenotypic variability, profile of women affected, degree of disease progression and range of hair loss profiles appears to confirm this [ 3435 ]. As in men, the pathogenesis of FAGA is based partly on the genes responsible for the production of androgens and their conversion to DHT, as well as the vulnerability of the respective receptors.

The androgen-sensitive miniaturization of the hair follicles is a pathognomonic symptom in both men and women. The presence of two copies of the androgen receptor in women, one of which is randomly inactivated, has raised some controversy about the role of AR in FAGA [ 36 ]. So far, only a few genes involved in this form of alopecia have been reported. One of them is the CYP17 gene 10q The gene was found in numerous studies to be present in patients with PCOS and their brothers, who demonstrated early androgenetic alopecia [ 193637 ].

Another gene identified in families with AGA is located on chromosome 3q26 [ 33 ]. Influence of androgen Two peripherally-circulating androgens which may have an influence on androgenic alopecia are dehydroepiandrosterone sulfate DHEAS and androstenedione, which are produced by the adrenal glands.

Testosterone and dihydrotestosterone, on the other hand, are synthesized primarily within the gonads [ 38 ]. The most important androgen in males is testosterone, formed in the interstitial cells of the testes. Griffin and Wilson [ 41 ], and Sawaya and Price [ 42 ] do not support the theory which assumes that elevated levels of androgens play a major role in MAGA, assigning greater significance to the genetically-determined increased sensitivity of hair follicles to the hormones.

The level of androgen receptors is 1. Male pattern alopecia never occurs in the temporal area and the region below the occipital area. In both men and women with a genetic predisposition, DHT binds to specific androgen receptors. Why does DHT affect people in different ways?

DHT affects people in varying ways. This may be due to: How levels are controlled and why they change are not yet understood. The role of 5-alpha-reductase 5-alpha-reductase 5-AR is the enzyme that converts testosterone into the much more potent androgen, DHT. If 5-AR levels increase, more testosterone will be converted into DHT, and greater hair loss will result.

There are two versions of 5-AR: Type 1 is predominantly found in sebaceous glands that produce the skin's natural lubricant, sebum. Type 2 mostly sits within the genitourinary tract and hair follicles. Type 2 is considered more important in the process of hair loss.

Finasteride, or Propecia, was approved for safety and efficacy inby the U. It is a selective inhibitor of type 2 5-AR. It is thought to act on the 5-AR enzyme that concentrates in the hair follicles to inhibit production of DHT. Studies of its efficacy have yielded apparently impressive results, but some people have questioned how effective it is.

Research has shown that it can stop baldness from progressing, and that, in some cases, hair will start appearing again.
