Is crossdreaming purely psychological or does it have a biological basis? Hormones may give us part of the answer.

There seems to be a general agreement among most psychiatrists who treat dysphoric male to female (MTF) crossdreamers and crossdressers that there is one "drug" that will alleviate some of their distress: Estrogen/oestrogen (the most important being estradiol/oestradiol), often misnamed the "female" hormone.
Estrogen and anti-androgens reduce possible emotional distress caused by crossdreaming
Harry Benjamin, the grand old man of transgender research, noted as early as 1966 that both "transvestites" (i.e. crossdressers) and non-transitioning transsexuals could benefit from taking estrogen, as it could be "helpful emotionally" or "needed for comfort or emotional balance".
There is little literature on this, but my contacts among therapists and activists confirm the well-known "secret" that doctors continue to prescribe estrogen to MTF crossdreamers, even when they do not plan to transition.
Some doctors also prescribe
antiandrogens, i.e. drugs that reduce the flow of testosterone, "the masculinizing hormone", in the bloodstream, or reduces the brains ability to make use of "T".
There are also antiandrogens that stop regular testosterone from being transformed into the more active dihydrotestosterone. The effects of antiandrogens are somewhat similar to the effects of estrogen: a reduction in the effects testosterone has on the mind and body.
Some doctors also combine the use of estrogens and antiandrogens to achieve the desired effect: a reduction in emotional distress and dysphoria. Crossdreamers who self-medicate on herbal alternatives often look for similar combinations, like when taking pueraria mirifica (for an estrogenic effect) and saw palmetto (for an antiandrogenic effect).
The two sides of sex hormones
It is important to note that you may influence the effects of sex hormones like testosterone and estrogen in two ways:
1. You may increase the amount of testosterone or estrogen in the body by way of pills or injections.
2. You may stop the body from absorbing the relevant hormones.
This relationship between "production" and "reception" of sex hormones is well known in sex research. It is not enough to
produce the relevant hormones. You also need the appropriate receptors to
absorb and make use of them. If a child with an XY "male" chromosome combination for some reason fail to develop the sufficient number of testosterone
receptors, that child may
develop a female body and mind.
It is also important to keep in mind that testosterone and estrogen are not really "male" and "female" hormones. A male fetus actually needs estrogen to produced the amounts of testosterone needed to develop a male body. The fetus transforms estrogen into testosterone, then the testosterone triggers the development of male sexual characteristics. At puberty another boost in testosterone turns boys into men.
On average men may have up till 20 times as much testosterone as women.
