I was interested in the interesting effects of the female hormone estrogen. When it is deficient, women suffer from depression, and this is often related to the menstrual cycle or the period after childbirth. Estrogen has exactly the same effect in the human body as so-called classic SSRI antidepressants, i.e., inhibition of serotonin reuptake, which increases the activity of serotonin receptors.
Smoking, nicotine lowers estrogen levels, which is negative (it's probably not for nothing that Amazonian shamans say tobacco is a typical male plant, i.e., a plant that causes the male element in a person).
Men also naturally have estrogen in their bodies, albeit at a lower level. Men can also be treated with estrogen – there is no risk that an increased level of this hormone will visibly change them – they will not start to turn into women – gender is clearly genetically determined in every single cell of our body, and an increased level of estrogen will not change genetic information.
Compared to SSRI antidepressants, estrogen is a natural human hormone and therefore has fewer side effects on health.
Scientists have also found that low estrogen levels can cause obsessive-compulsive disorder. Thus, estrogen could be a possible treatment for this disorder.
Scientists have also found that low estrogen levels are responsible for overeating in women – and the solution to overeating can also be addressed with estrogen.
Of course, you cannot buy estrogen in a pharmacy without a doctor's prescription.
However, estrogens are present in dietary supplements (they are available over-the-counter) in the form of phytoestrogens, isoflavones.

If the isoflavone supplement is not sufficient and does not sufficiently increase serotonin levels, there is another aid – a tryptophan supplement – a precursor of serotonin. The combination of isoflavones and tryptophan will multiply the effect. However, you must handle tryptophan carefully so that serotonin levels do not increase to an extreme degree – serotonin syndrome can be a very serious condition.

A disadvantage of estrogens may be an increased risk of breast cancer at excessive levels.
