  Purpose
The purpose of this study is to determine if the combination therapy of lifestyle intervention and use of Metformin together will improve ovulation induction and hyperandrogenemia in women with polycystic ovary syndrome, by gathering data from adult and adolescent females.

Primary Outcome Measures:
  • Change in Testosterone After 6 Months of Treatment [ Time Frame: baseline and 6 months ]

Secondary Outcome Measures:
  • Ovulation Rate [ Time Frame: 6 months ]
    Ovulation is defined as a binary outcome; ovulated at least once vs. did not ovulate during the treatment period.

  • Change in Insulin Sensitivity Index After 6 Months of Treatment [ Time Frame: baseline and 6 months ]

Enrollment: 114
Study Start Date: October 2004
Study Completion Date: March 2008
Primary Completion Date: March 2008 (Final data collection date for primary outcome measure)

Experimental: Metformin
Metformin
Drug: Metformin
Medication was initiated in a step-up fashion every five days, from one tablet per day to four (500 mg per tablet).
Behavioral: Lifestyle Intervention
A combined intervention of diet and exercise was employed with the goal of achieving an average weight loss of at least 7% of initial body weight over six months with a prescription of 150 min/week of exercise combined with a low-calorie diet.

Detailed Description:
PCOS is characterized by excess circulating androgen levels and chronic anovulation. PCOS is also characterized by insulin resistance and hyperinsulinemia. Several recent studies in a variety of non-hospital based populations have provided evidence that the incidence of hyperandrogenic chronic anovulation is in the range of 4-6% of the female population. Improvements in insulin sensitivity in women with PCOS, either through lifestyle changes or through pharmaceutical intervention, have consistently resulted in a marked improvement in the reproductive and metabolic abnormalities in PCOS. The primary objective in the adult female population is to determine that combination therapy will improve ovulatory frequency. Secondary objective is to improve circulating hyperandrogenemia and insulin sensitivity then single agent therapy. The primary objective of the adolescent population is to determine that the combination therapy will improve hyperandrogenemia. Secondary objective is to improve ovulatory frequency and insulin sensitivity than just the use of a single agent therapy.
