I received an interesting question regarding sex-edging orgasms and accelerated hair loss. Here is some info from the web:

There is a direct correlation between sexual activity and testosterone levels in the blood. However, the DHT and 5-alpha reductase levels have been shown to impact hair loss. 

1) A Hidden Factor in Elevation of 5-alpha Reductase Levels

It’s not a high serum DHT that contributes to hair loss–no! It is an elevated 5-alpha reductase level. In fact just to be clear, research shows that a high blood level of DHT is inversely correlated to balding. However, a high 5-alpha reductase level can increase DHT in local tissues, and that appears to be the factor in hair loss. Getting that important discussion out of the way, there are many hidden reasons why the enzyme 5-alpha reductase increases. Sometimes it is a result of medication, other times it could be thyroid problem and/or an endocrine system problem. http://longevitypost.com/a-hidden-factor-in-elevation-of-5-alpha-reductase-levels/

2) Hair Loss & Low Testosterone | LIVESTRONG.COM

Hair loss may occur through several mechanisms, however the only form related to testosterone levels is known as androgenetic alopecia. A hereditary disorder characterized by thinning of scalp hair, androgenetic alopecia occurs in both men and women through an androgen mediated mechanism. While this syndrome is technically a low testosterone state, in fact the body is experiencing high androgen levels due to the mechanism of dihydrotestosterone (DHT), a metabolite of testosterone with potent androgenic effects

Hair Physiology

In a healthy hair follicle, circulating DHT binds androgen receptors located on hair follicles. DHT has a potent effect on these receptors, directly inhibiting the growth of the hair follicle. This occurs in normal individuals, allowing accurate control of the hair growth cycle.

Hair Loss Pathogenesis

Circulating testosterone is converted peripherally to DHT by the enzyme 5-alpha reductase. Patients with elevated 5-alpha reductase levels may develop a high DHT/low testosterone state. Pathologic hair loss occurs when the individual’s DHT reaches levels at which the inhibitory effects outweigh the stimulatory forces on the hair follicle. Therefore, while low testosterone is associated with hair loss, the pathologic mechanism occurs via the elevated DHT levels. This results in progressively shorter, less pigmented hair production, which ultimately presents as hair thinning and loss. (http://www.livestrong.com/article/302151-hair-loss-low-testosterone/)

3) Does oragasm or having sex or sexual activity increase DHT which cause hairloss? Doctor Answers, TipsThere is no correlation between sexual activity and DHT levels, so you can certainly feel free to have a very active sex life and any degree of male pattern hair loss that you will experience is… SHOW MORE genetically determined and other than the addition of Finasteride, topical nutrient serum shampoos, low-level light therapy, plasma rich protein and the amount of recession and thinning that you experience will be genetically
