DATABASE OF FEMALE REPRODUCTIVE HORMONES
Data provided by Professor Paul Biscof Département de Gynécologie et d'Obstétrique Hôpital Universitaire de Genève
Use the database that contains the data from 20 healthy women volunteers aged 20 to 35 years old in Geneva Switzerland. These women had not been taking oral contraceptives for at least 3 months before the start of the study. Daily morning blood samples were taken on starting on the first day of their menstrual cycle (determined by the beginning of their menstrual bleed = menses) and continued to the first day of their next menstrual bleed.
Six hormones were measured in the blood samples:
UI = International Units
The data was complemented by ultrasound scans of the volunteers’ ovaries to determine the stage of the follicles.
