Brief Summary:
The purpose of this study is to compare the vaginal health between premenopausal and postmenopausal women before and after using oral "estradiol" for 14 days then "estradiol" and "progesterone" for 14 days.

Condition or disease Intervention/treatment Phase
Menopause Drug: oral estradiol 1.0 mg Drug: oral progesterone 100 mg Phase 3

Detailed Description:

This research project recruits 10 healthy, premenopausal women (aged 20-40 years-old) with regular menstrual cycle with interval of 24-35 days and duration of 2-7 days and 10 healthy postmenopausal women (aged 45-60 years-old) with an intact uterus and at least 12 months but not more than 36 months of spontaneous amenorrhea.

Premenopausal women will not receive any study medication(s). Postmenopausal women will be assigned the intervention described below.

• Oral "estradiol" 1.0 mg tablet for 14 days, then oral "estradiol" 1.0 mg tablet and "progesterone" 100 mg capsule for 14 days

Actual Primary Completion Date : August 2018
Actual Study Completion Date : August 2018

Arm Intervention/treatment
No Intervention: 1.Premenopausal women
No treatment
Experimental: 2.Postmenopausal women with hormones
Oral hormone therapy will be given to women in this group. Daily dose of oral "estradiol" 1 mg will be given the first 14 days after enrollment. Then a daily dose of oral "estradiol" 1 mg and "progesterone" 100 mg for 14 days will be given during the following 14 days.
Drug: oral estradiol 1.0 mg
one tablet of oral estradiol 1.0 mg once a day for 28 days
Other Name: Estrace

Drug: oral progesterone 100 mg
one tablet of oral progesterone 100 mg once a day for 14 days
Other Name: Prometrium

Primary Outcome Measures :
  1. baseline vaginal cytokines [ Time Frame: 1 month ]
    Determine the differences in vaginal cytokines Il-1β and IL-8 between premenopausal and postmenopausal women.

Secondary Outcome Measures :
  1. vaginal cytokines changes [ Time Frame: 1 month ]
    Determine the changes in vaginal cytokines in postmenopausal women following treatment with estradiol then estradiol and progesterone compared to the normal menstrual cycle changes in young premenopausal women.
