Candidates for this study must meet ALL of the following criteria: Inclusion criteria for female participants: 1. Age: ≥ 18 to ≤ 40 years 2. Diagnostic of PCOS confirmed by at least 2 of 3 Rotterdam criteria, defined as: 2.1 Infertility associated with chronic anovulation or oligomenorrhea, defined as spontaneous intermenstrual periods of ≥35 days or a total of ≤9 menses per year 2.2 Ultrasonographic evidence of PCOS (ovarian volume ≥ 10ml and/or follicle number per ovary of ≥ 20) 2.3 Evidence of hyperandrogenaemia: either clinical (hirsutism or acne) or biochemical (raised serum concentration of androgens (testosterone ≥ 2.5nmol/l, or FAI \> 4) 3. Ovarian accessibility: determined by ability to bring transvaginal ultrasound transducer into close proximity to ovaries 4. Resistance to first-line pharmacological treatment, defined as at least 2 consecutive non-ovulatory cycles, including at least 1 cycle at the highest dose deemed clinically relevant for the patient 5. At least one patent tube and normal uterine cavity as determined by sonohysterogram, hysterosalpingogram, or hysteroscopy/laparoscopy within the last 3 years 6. Willing to comply with protocol-specified follow-up evaluation 7. Signed informed consent Couple inclusion criteria: 8.
