Introduction. Polycystic ovary syndrome is the most frequent endocrine disturbance in the reproductive period of women?s life and the most frequent cause of anovulatory infertility. Ovulation and pregnancy in patients having polycystic ovary syndrome may be a result of a wide range of therapeutic options, and the treatment assumes a gradual approach - from simple noninvasive to expensive and demanding procedures. Material and Methods. A systematic literature survey concerning the efficiency of particular ovulation induction methods in respect of the reproductive outcome was carried out with the aim of establishing the algorithm for ovulation induction in infertile patients having polycystic ovary syndrome. The search was confined to clinical investigations performed on human subjects, reported in English in the period from the beginning of 2010 to June of 2014. Conclusion. As a conclusion of this system?atic survey of the efficiency of ovulation induction methods, which confirms and supplements the knowledge in this field, it is possible to form the algorithm for ovulation induction in infertile patients having polycystic ovary syndrome, consisting of the following subsequent steps: 1) modification of life style, 2) induction with clomiphene citrate 3) use of metformin, 4) use of aromatase inhibitors, 5) application of gonadotropins and laparoscopic ovarian drilling - as a second-line treatment, and 6) assisted reproductive techniques.

This prospective observational study was conducted on 220 patients with polycystic ovary syndrome (PCOS) and subclinical hypothyroidism (SCH) who were allocated into two groups; group one (n=112) received clomiphene citrate (CC) plus thyroxine while group two received only CC for ovulation induction. Patients receiving CC and thyroxine exhibited higher ovulation rate (p<0.001), higher endometrial thickness (p<0.05), higher number of dominant follicles (p<0.001) and higher pregnancy rate (p<0.001) compared to their counterparts receiving only CC. Thyroxine supplementation improves ovulation and pregnancy rates in infertile patients with PCOS and SCH receiving CC for ovulation induction who are therapy naïve.

Background: The aim was to compare ovulation induction protocols in anovulatory patients, who make up a significant percentage of infertility patients, and to determine the most appropriate treatment for patients in the clinic based on the findings.Methods: The effectiveness of clomiphene citrate (CC) and letrozole (aromatase inhibitor) in ovulation induction treatments were retrospectively compared in patients who applied for infertility in the last 5 years and were found to be anovulatory. 20 of these patients were being treated with clomiphene citrate, while the 18 were being treated with letrozole.Results: The study included a total of 38 anovulatory infertile patients. The mean age of the patients was found to be 29.3. When the endometrial thicknesses (ET) after the treatment were compared, the first group's mean EC was 6.1, while that of the second group was 9.05. The endometrial thicknesses measured after the treatments were found to be significantly different, which were consistent with other studies in the literature. Post-treatment ovulation responses were similar with 55% in both groups. In the evaluation of pregnancy outcomes, 20% of pregnancy was achieved in the first group and 33% in the second group.Conclusions: The use of letrozole, an aromatase inhibitor, may be suggested as an alternative to CC in the ovulation induction protocol in our clinical practice, particularly in obese patients.

Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility in women of reproductive age. Lifestyle change is considered the first line treatment for the management of infertile anovulatory women with PCOS, and weight loss for those who are overweight or obese. First line medical ovulation induction therapy to improve fertility outcomes is letrozole, whilst other less efficacious ovulation induction agents, such as clomiphene citrate, metformin, and metformin combined with clomiphene citrate, may also be considered. Metformin combined with clomiphene citrate is more effective than clomiphene citrate alone. In obese women with PCOS, clomiphene citrate could be used in preference to metformin alone whilst clomiphene citrate could be added to metformin alone in order to improve reproductive outcome in all women with PCOS. Gonadotrophins, which are more effective than clomiphene citrate in therapy naïve women with PCOS, can be considered a first line therapy in the presence of ultrasound monitoring, following counselling on the cost and the potential risk of multiple pregnancy.
