Résumé
To predict ovulation in subfertile women using serial follicular growth (FG) and serum hormone measures (estradiol (E2), luteinizing hormone (LH), and progesterone (P) levels) in mathematical models. This was a prospective observational study of 116 subfertile women aged between 18 and 40 years. FG was assessed by serial transvaginal ultrasonography starting from cycle days 8-12, depending on cycle length. Once the dominant follicle reached 15-16 mm, hormone levels were assessed daily. The primary outcome measure was ovulation (O A mathematical model was constructed using exponential regression to relate days until and after ovulation with P levels. The O Serum P levels display a highly predictable linear curve in natural cycles, which enables the prediction of ovulation. The O
