Good health and metabolism makes this prolactin spike practically insignificant - drink more milk, take Vitamins ADEK to boost calcium metabolism which will boost dopamine and lower prolactin, abstinence can be a stressor too just like too much ejaculating especially if you feel horny and get erections and feel like indulging but keep denying itMy thinking is that negative hormonal profiles associated with pattern hair loss are:
1) elevated estrogen / estradiol -> Solution: general health and dietary improvements, plus avoiding plastics / detergents and endocrine disruptors, progesterone use.
2) elevated serotonin -> Solution: promote gut health (avoid food sensitivities) and possibly some cypro use etc.
3) elevated prolactin -> Solution: possibly lisuride, and semen retention**
4) elevated cortisol / adrenalin -> Solution: lifestyle improvements / stress management, carbohydrate intake
5) elevated parathyroid hormone -> Solution: Ca:P Ratio - Calcium supplementation and sensibly reducing muscle meat intake to limit phosphorus
** In short, male orgasm is associated with elevations in prolactin shortly afterwards. These prolactin levels are supposed to return to base-line within a few hours to one day. However, if the male is constantly "spilling his seed" on a daily basis, then it is likely that prolactin will remain elevated above the natural baseline indefinitely - or at least, be constantly spiking. This may be especially true with masturbation - which *apparently* has slightly worse impacts on hormonal profiles compared to sex with a partner, due to the absence of bonding hormones that are released w. a partner.
In addition to hair loss, high prolactin has been associated with a number of other conditions such as gynecomastia, low energy, low mood etc.
Whether this strategy will help or not, I cannot say. But I think that quitting masturbation and viewing sex as an activity to produce children, rather than just for physical pleasure, may be beneficial for me in general.
