The Lowdown on Progesterone

Progesterone is a hormone naturally produced by the female reproductive tract. Many trans women believe it has value in the physical transition process and particularly in relation to the development of breast tissue. However, in the trans arena, there is much misinformation about its benefits, little information on its adverse effects and little understanding of its action in the genetic female. The Lowdown on Progesterone has been written by Dr Richard Curtis.

Department of Health Hormone Therapy booklet

This publication available in booklet form has been produced by a team that includes doctors and trans people to help you understand and answer some of your questions about hormone treatment for trans people.

This publication gives trans men (female to male) and trans women (male to female) straightforward information about the benefits of hormone therapy and the risks and side effects.

Every individual is different, and guidance about hormone therapy should always be used flexibly in response to individual needs.

If you are thinking about starting hormone therapy, you may find it helpful to share the information in this booklet with a spouse or partner or other family members.
