Cross fertilisation between the two disciplines may lead to a better understanding for example of Osteoporosis (Preston et al, 2002) We need to improve the treatment procedures especially for those being treated simultaneously for both conditions. Male to Female Transsexuals. Initial treatment is to achieve Testosterone and Oestradiol serum levels appropriate to a natal female. Subsequently Genital Reassignment Surgery (GRS) may be performed (not in all cases) which will include orchiectomy, and possibly, penotomy, and vaginoplasty. Orchiectomy maybe performed on its own but where vaginoplasty is proposed Scrotal tissue will be required as part of the reconstructive procedure. Post Orchiectomy The dose of Anti androgens will require re-evaluation in a downwards. Direction. In some cases the anti androgen effect of Oestradiol on its own is sufficient to control Androgen (Testosterone) levels in Transsexuals. Initially (1940s) oestradiol was the only available anti androgen and coupled with orchiectomy was the treatment available. Castration (sic) or Orchiectomy was still the procedure of choice until the availability of non steroidal anti-androgens References
