Towards the end of the preregistration period choices for paediatrics 0.18 mg alesse, general medicine, general surgery, and obstetrics and gynaecology exceed opportunity. Preferences for pathology and radiology are about matched to opportunity, and psychiatry, general practice, and public health are undersubscribed. However, fashions change all the time in medical careers, and there is a move back towards general practice in some parts of the country, but job opportunities still exceed those wishing to take them up. Over the subsequent few years 25–33% of doctors change their choices, some more than once. About 40% of the changes of preference (and about 60% in women with children) are because of family commitments. Specialties such as general practice now come into their own, being more readily compatible with other responsibilities, both in flexibility of working practice and in the earlier attainment of a settled home and secure income. Hospital specialties which allow other commitments either through well organised duty rotas or light on call responsibility or by providing good opportunities for part time work include anaesthetics, accident and emergency, psychiatry, pathology, radiology, oncology, medicine for the elderly, rehabilitation medicine, and medical specialties such as dermatology, genitourinary medicine, and palliative care. Overall, a recent survey showed that half of women and a quarter of men considered marriage to have been a constraint on their career in medicine. Eventually, preconceived ambitions have to be balanced against the practicalities of personal commitments and professional training. A determined effort is being made to introduce good opportunities for "flexible training", but more still needs to be done to reduce the conflict between family responsibilities and a career in medicine and to diminish the relatively greater disadvantage of women. As Yvonne Noble, a sociologist, has written: Adjustments in the profession must be inevitable: when the adjustments are made it is essential that they do not continue to disadvantage those (men as well as women) who recognise their need for and responsibility to personal partners and children. Better career advice is needed, both at medical school and in the early postgraduate years, but it may be of rather limited value until the circumstances of personal life unfold. Most doctors eventually find their way through the maze but they and their families deserve more readily available signposts and smoother paths to a permanent post.
