Single serum progesterone determinations were made in 79 apparently normal women with a regular menstrual cycle. A normal range (40 subjects) was derived from the concentrations in the follicular phase and used to define an "'anovular" range for luteal phase values (nine out of 39 subjects). The remaining luteal phase values were used to construct an "ovular" range for the luteal phase and, within this rRnge, to define a group of values. (less than the 20th-centile) which could be described as a "defective luteal phase." The cut off limits between ovular and anovular and between normal and defective luteal phases were respectively two and four times the follicular phase median.

Objective-To compare the effectiveness of three methods of taking an antenatal history on the quality ofobstetric care.Design-Randomised controlled trial. Setting-Antenatal clinic of St James's University Hospital, Leeds.Subjects-2424 women attending the hospital for the first (booking) visit.Interventions-Histories were taken by midwives using an unstructured paper questionnaire, a structured paper questionnaire (incorporating a checklist), or an interactive computerised questionnaire (incorporating 101 clinical reminders).Main outcome measures-The number of clinical responses to factors arising from the antenatal booking history according to method of taking the history. Actions were categorised as medical and surgical, obstetric, personal, current symptoms and treatment, related to maternal age, and related to two common actions (cervical smear testing and dental hygiene) and were weighted for clinical importance by 10 obstetricians.
