- As gender-affirming treatment may have a negative impact on fertility, reproductive health counseling to patients seeking medical or surgical gender-affirming treatment should be provided, including the option to undergo fertility preservation (FP). Experiences of transgender men undergoing FP treatments aimed at oocyte freezing have reported a negative impact of the treatments on gender dysphoria. No previous studies have investigated the experiences of health care professionals’ (HCP) when caring for transgender men undergoing such treatments. Aim: The aim of this study was to investigate HCP’s attitudes and experiences when meeting transgender men undergoing FP through oocyte freezing. Methods: Individual interviews were conducted in 2016 with 13 HCPs working at a Reproductive Medicine clinic in Sweden. Data were analyzed by thematic content analysis. Results: The main theme found, How to maintain professionalism, showed that HCPs experienced important challenges to their professionalism when their preconceived opinions and values about gender and transgender were confronted. Discussion: Our findings demonstrate the need of continuous efforts on assessing learning needs as well as addressing preconceived opinions and values of HCP. By gaining knowledge and self-confidence in the care of transgender individuals undergoing FP, a professional care for transgender people can be achieved and a safe environment can be established for the patients. This in turn may alleviate some of the distress that may arise when transgender men undergo FP.

- DIII-D physics research addresses critical challenges for the operation of ITER and the next generation of fusion energy devices. This is done through a focus on innovations to provide solutions for high performance long pulse operation, coupled with fundamental plasma physics understanding and model validation, to drive scenario development by integrating high performance core and boundary plasmas. Substantial increases in off-axis current drive efficiency from an innovative top launch system for EC power, and in pressure broadening for Alfven eigenmode control from a co-/counter-I p steerable off-axis neutral beam, all improve the prospects for optimization of future long pulse/steady state high performance tokamak operation. Fundamental studies into the modes that drive the evolution of the pedestal pressure profile and electron vs ion heat flux validate predictive models of pedestal recovery after ELMs. Understanding the physics mechanisms of ELM control and density pumpout by 3D magnetic perturbation fields leads to confident predictions for ITER and future devices. Validated modeling of high-Z shattered pellet injection for disruption mitigation, runaway electron dissipation, and techniques for disruption prediction and avoidance including machine learning, give confidence in handling disruptivity for future devices. For the non-nuclear phase of ITER, two actuators are identified to lower the L-H threshold power in hydrogen plasmas. With this physics understanding and suite of capabilities, a high poloidal beta optimized-core scenario with an internal transport barrier that projects nearly to Q = 10 in ITER at ∼8 MA was coupled to a detached divertor, and a near super H-mode optimized-pedestal scenario with co-I p beam injection was coupled to a radiative divertor. The hybrid core scenario was achieved directly, without the need for anomalous current diffusion, using off-axis current drive actuators. Also, a controller to assess proximity to stability limits and regulate β N in the ITER baseline scenario, based on plasma response to probing 3D fields, was demonstrated. Finally, innovative tokamak operation using a negative triangularity shape showed many attractive features for future pilot plant operation.
