Title
Effectiveness of sequential Letrozole and Gonadotropins therapy for ovulation induction in infertile women with PCOS: A systematic review and meta-analysis of randomized controlled trials (RCTs)
Review Question
What is the effectiveness of sequential letrozole and gonadotropins therapy versus other interventions or placebo for ovulation induction in infertile women with polycystic ovarian syndrome?
Study Type Included
Randomized controlled trials (RCTs)
Condition Being Studied
Polycystic ovarian syndrome (PCOS) is a highly prevalent, genetically complex, and heterogeneous endocrine disorder in reproductive-aged women, affecting 5% to 20% worldwide. It is a common cause of hyperandrogenism, anovulatory infertility, menstrual dysfunction, and hirsutism. It appears to be associated with an increased risk of metabolic abnormalities such as insulin resistance, hyperinsulinism, type 2 diabetes mellitus, dyslipidaemia, cardiovascular diseases, and endometrial carcinoma. PCOS accounts for more than 80% of women with anovulatory infertility. Ovulation induction therapy is a classical treatment for women with anovulatory PCOS who wish to conceive.
Participant
It will include RCTs reporting infertile women with PCOS of any age, race or ethnicity. Women with PCOS who are diagnosed by Rotterdam Criteria, with normal TSH, and prolactin levels, and with normozoospermic male partners, having unprotected timed-intercourse and duration of their infertility is longer than 1 year. All other studies reporting women with infertility caused by disorders other than PCOS, with a history of ovarian surgery or complications with endometriosis or pelvic adhesion, patients complicated with liver, kidney, or thyroid dysfunction, women with CAH and gynaecological surgeries, women with autoimmune diseases, tubal obstruction, and who are allergic to relevant drugs will be excluded from the review.
Animal
Human Disease Modelled
Intervention
We will include studies reporting sequential letrozole and gonadotropins for ovulation induction. Letrozole, an aromatase inhibitor, in combination with gonadotropins, has shown promising results in women with PCOS, including CC-resistant PCOS patients. Gonadotropins, when given in combination with ovulation-inducing drugs, reduce the risk of complications while maintaining higher pregnancy rates. In clinical trials, letrozole plus gonadotropins sequential therapy has resulted in higher pregnancy rates and live births than any other intervention, including CC. Moreover, It proved to be efficient in the case of CC-resistant PCOS patients due to its indirect effect on estrogen.
Comparator Control
The placebo or other standard regimens for ovulation induction in infertile women with PCOS.
Main Outcome
The primary outcome of this review will be ovulation induction. Secondary outcomes may include follicular growth, increased rate of pregnancy and ultimately live births in infertile women. Measures of effect Relative Risk of main outcome will be measured.
