The subjects studied exhibited similar length individual basal body temperature (BBT) charts showed a peak occurring at midcycle. Urinary FSH LH were measured by rat ovarian weight augmentation ascorbic acid depletion methods, respectively. Results expressed terms NIH-FSH-S2 (“FSH” activity), NIH-LH-S1 (“LH” activity) Second International Reference Preparation for Human Menopausal Gonadotrophins (2nd IRP). composite curve derived summating days preceding or following day minimum BBT on each cycles. It found that present cycle, with tendency to rise (+) 1–2; also showing significant 1–2, 3–4 5–6. Also i...
