A few recent studies done on the effects of estrogen showed that this hormone alleviates numerous psychotic symptoms of women suffering from schizophrenia. These findings may be used as an important foundation for future studies of the relationship between estrogen and mental illnesses.

One of the latest studies included 102 women with schizophrenia. Half of the study participants received 100 mg of estradiol, a form of estrogen, via skin patches while the other half was used as a control group. The group of women who wore the hormonal patches had decreased levels of positive psychotic symptoms such as hallucinations and delusions in comparison to the control group.
On the other hand, there is no information for negative symptoms of schizophrenia regarding social interactions.

One of the reasons these studies are conducted is, of course, to see whether estrogen therapy could be used as a treatment method and as a prevention of relapses in women with schizophrenia as well as other mental conditions.

Estrogen was found to be especially beneficial for women after childbirth and menopause.
