Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This study is intended to provide the first determination of systemic changes in the ratio of FSH21/FSH24 and determine if estradiol increases the FSH21/FSH24 ratio in the first morning urine of women. To take part in this study, the participant must be willing to collect the first morning urine on particular mornings of the menstrual cycle and be available for blood draws on those mornings. Additionally for postmenopausal participants, the participant must be willing to use topical estrogen, EstroGel©, for 14 days and be willing to collect the first morning urine on particular mornings and again be available for blood draws on those mornings. For the postmenopausal participants with an intact uterus, the participants must be willing to take an oral progestin, micronized progesterone, for 12 days following the completion of the study.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Premenopausal women
Participants will bring into clinic their first voided urine of the day on cycle days 9, 12 and 15 in a urinary collection kit that will be given. A urine dip stick will be performed on the samples. Each time they bring in a sample, they will have a serum blood draw for estradiol and FSH.
No interventions assigned to this group
Postmenopausal women
Participants will bring into clinic their first voided urine of the day on assigned days 1, 4 and 7 in a urinary collection kit that will be given. A urine dip stick will be performed on the samples. Each time they bring in a sample, they will have a serum blood draw for estradiol and FSH. The participants will then be started on EstroGel© for 14 days from day 7-21. During that time that they are on EstroGel©, the participants will bring into clinic their first voided urine of the day on assigned days 15, 18, and 21 in a urinary collection kit that will be given. A urine dip stick will be performed on the samples. Each time they bring in a sample, they will have a serum blood draw for estradiol and FSH. After the last urinary collection and blood draw, they will discontinue the EstroGel and be started on micronized progesterone if they have a uterus for 12 days.
Estradiol Transdermal Product
Hormone replacement therapy will be given to postmenopausal women for up to 1 month.
