I can imagine that interactions of masculinizing hormones taken for transition, and side effects of these (eg vaginal atrophy) could be an important aspect of physiology, and the potential actions of these drugs with other pregnancy conditions eg preeclampsia may be significant aspects to study and monitor for effects on the parturient, their pregnancy and neonatal health. Also it would be interesting to know how and why these individuals who profess dysphoria and physically or medically transition choose to become pregnant including through the use of reproductive technology. These would be useful things to know in planning safe care around this group of patients.
Thing is, Sally Hines has no expertise in any of that (very relevant) Science Stuff. The £500,000 will buy a survery, done by her students, and a load of blather. This will tick a box about inclusion and perhaps pad someone's CV, for comissioning this boondoogle.
Some guidance may be issued, which will be ignored by overworked midwives. Career minded managers may vomit back up some of the blather at meetings or interviews.
Since the only useful things in the blather could be summed up by 'treat people with respect', and since the number of pregnant women who still think they are biologically male are incredibly tiny, absolutely no practical use will be made of this 'research'.
