Good lord. Not anoter one of these stupid damn threads. Masturbation does not cause hairloss. Neither does shampoo, hats or reading pulp fiction. It is a genetically inherited sensitivity to androgens causing your hair to minaturise to the point that it is no longer produced at all. The rest is just bunk.
i am not looking for a cause, only for a correlation. As you may know ejaculation releases prolactin, which does have an effect on hair. Aside from that, the hormonal changes occuring during sex are "androgen" related.
It has been done to death. The temporary increase in androgens around the act of intercourse is regarded as insignificant and has been dismissed by just about any serious person in the field of hairloss. The prolactin increase would only be temporary in order to normalise dopamine levels and I haven't heard any research about Prolactin and hair loss. Would be interested to hear it. I really don't see where you are going with this.
