Does metformin affect FSH levels?
Results: Metformin markedly reduced FSH but not forskolin-stimulated aromatase expression and activity. This effect was exerted by inhibition of basal and ligand-induced up-regulation of FSHR expression.
How long does metformin take to work for PCOS to get pregnant?
There is some benefit starting about a month after beginning metformin. Metformin has a more substantial benefit for fertility when the woman has been taking it for at least 60 to 90 days.
Does metformin increase fertility in PCOS?

How many days should I take metformin for PCOS?
A start dose of 500 mg daily during the main meal of the day for 1–2 weeks can lessen the side effects and allow tolerance to develop. A weekly or biweekly increase by 500 mg a day can then be pursued as required until a maximum dose of 2500–2550 mg/day is reached depending on the clinical benefit and side effects.
Does metformin lower LH levels?
Conclusions. In women with PCOS, Metformin induces a prompt decrease in LH-stimulated T secretion after only several days of use. This action precedes the medication’s effects on insulin sensitivity or weight loss.
Does metformin help follicles grow?
We also found an improvement in follicular development, with a lower percentage of small follicles and cysts and a higher percentage of antral follicles and corpora lutea after metformin administration.
How soon after metformin will I ovulate?
Following the treatment protocol, 19/48 (40%) resumed spontaneous menses and showed evidence of ovulation with metformin alone. Ten of 28 (36%) used CC (50 mg) in conjunction with metformin therapy. The median time to onset of spontaneous menses was 30 days after starting metformin.
Does metformin make you ovulate sooner?

Does metformin affect ovulation?

How effective is metformin in PCOS?
The use of metformin in PCOS has received a lot of attention for obvious reasons. Once thought of as a wonder drug, the accumulating evidence on the efficacy of metformin has been disappointing. The lack of an emphatic or overwhelming efficacy is largely due to the patients’ variability in phenotypes and their metabolic parameters.
Can metformin prevent T2DM after a washout period?
In a follow on study, it was reported that after a washout period, 25% of the metformin benefits in preventing T2DM no longer existed [The Diabetes Prevention Program Research Group, 2003].

As women approach menopause their baseline FSH levels (day 3 of their cycle) will tend to gradually increase over the years. When they run out of follicles capable of responding, their FSH will be high and they stop having periods. Why do we measure the FSH level on day 3?
