Summary
This research study aims to investigate the effect of adding Alpha lipoic acid (ALA) supplement to letrozole treatment in infertile women with polycystic ovary syndrome (PCOS). The study will include 150 PCOS participants seeking fertility treatment. They will be randomly divided into two groups - control and intervention. Both groups will receive standard PCOS care including lifestyle counseling. The control group will be treated with letrozole only. The dose will start at (2.5 mg) for 5 days and can increase up to (7.5 mg) based on response. The intervention group will take ALA supplements along with letrozole treatment. ALA tablets (600mg) will be given three times daily starting from day 3 of the menstrual cycle till human chorionic gonadotropin (HCG) injection day. Letrozole dose for the intervention group will also follow the same incremental protocol as the control group. Patient monitoring will involve trans-vaginal ultrasound scans on certain cycle days to check follicle growth and the thickness of uterus lining. Once a follicle reaches 18mm in size, an intramuscular HCG injection will be given. Couples will be asked to have intercourse 36 hours after the injection. Pregnancy will be tested two weeks later if menstruation does not occur. Metabolic, hormonal, and ultrasound parameters will be recorded at baseline and follow-ups. All adverse effects of the treatment will be noted. The study period will be a maximum of 3 treatment cycles or untill pregnancy is achieved. Outcome measures include ovulation and pregnancy rates. The effect of ALA on metabolic parameters (fasting glucose, fasting insulin, BMI and HOMA-IR), hormone levels (mid-luteal progesterone and serum estradiol), and follicular growth will also be assessed. Proper sample size and randomization methods will be followed. A Statistical analysis of collected data will help determine if ALA has additional benefits when combined with letrozole for PCOS fertility treatment. Finally, the results will be statistically analyzed. Statistical analysis will be done using the SPSS statistical software package.

Interventions
Alpha-lipoic acid (ALA), also known as 1,2-dithiolane-3-pentanoic acid or thioctic acid, is found in the mitochondria. It acts as an enzymatic cofactor for various enzymes in the Kreb's cycle. ALA has many beneficial properties making it a potential candidate for various clinical disorders. It is considered the universal or "ideal" antioxidant as it is both water-soluble and fat-soluble facilitating its passage across membran. ALA has direct as well as indirect anti-inflammatory effects. Being a potent antioxidant leads to a reduction in oxidative stress which in turn reduces inflammation, meaning ALA indirectly has anti-inflammatory effects. To add to ALA's benefits, it has anti-inflammatory properties that are independent of its antioxidant effects.
Letrozole is an aromatase inhibitor that controls the conversion of androgen to estrogen and increases ovarian androgens. The administration of letrozole in the follicular phase removes the effect of negative estrogen feedback on the pituitary and hypothalamus, thus increasing the gonadotropins\]. When Letrozole blocks estrogen production, it encourages the body to produce more follicle-stimulating hormone (FSH).The additional FSH stimulates egg development and increases the likelihood of ovulation. Kar, S. Found that letrozole has excellent pregnancy rates compared to clomiphene citrate, Letrozole should be considered at par with clomiphene citrate as first-line drug for ovulation induction in infertile PCOS women.
