RESUMO
The primary investigations and starting the hormonal treatment of transsexual persons takes place in Helsinki and Tampere University hospitals as part of the real life period. The hormones used are estrogen and anti-androgen for MtoF and testosterone for FtoM persons. The medication suppresses the endogenous sex-hormone production and brings about the desired features of the other sex. While the recommended doses result in physiological hormone levels, higher doses do not hasten or increase the desired changes and are a health risk. After the transition period, the follow up is referred to the person's home district. The physical and psychological status and laboratory values are evaluated at the yearly follow-up doctor visits. Although the hormone doses are lowered and percutaneous administration route is favored upon aging, stopping the medication is not recommended.

In many clinics, good-quality embryos are selected for embryo transfer and cryopreservation at the cleavage stage, and poor-quality embryos are discarded. The aim of this retrospective study was to examine how many repeated IVF cycles could be avoided by culturing the cleavage stage poor-quality embryos to blastocyst stage and transferring them after vitrification and warming (604 IVF and intracytoplasmic sperm injection [IVF-ICSI] cycles were included). Poor-quality cleavage stage embryos not eligible for transfer or cryopreservation were cultured until day 5 or 6, and those developing to the blastocyst stage were vitrified. The rate of vitrified blastocysts and clinical pregnancy and delivery rate of the warmed blastocysts was evaluated. The effect of the extended culture on the cumulative delivery rate, and the number of avoided new treatment cycles was calculated. The surplus blastocysts resulted in clinical pregnancy, spontaneous abortion and delivery rates of 24.6%, 27.3% and 17.2% respectively. The use of surplus blastocysts raised cumulative delivery rate from 43% to 47% and 53 repeated new cycles were avoided. This study shows that the cumulative delivery rate can be increased, and repeated IVF-ICSI treatments avoided by using blastocysts developing from poor-quality cleavage stage embryos, which otherwise would have been discarded.
