Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Candidates for this study must meet ALL of the following criteria:

Inclusion criteria

for female participants:

  • Age: ≥ 18 to ≤ 40 years
  • 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)

  • Ovarian accessibility: determined by ability to bring transvaginal ultrasound transducer into close proximity to ovaries
  • 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
  • At least one patent tube and normal uterine cavity as determined by sonohysterogram, hysterosalpingogram, or hysteroscopy/laparoscopy within the last 3 years
  • Willing to comply with protocol-specified follow-up evaluation
  • Signed informed consent

Couple inclusion criteria:

  • Normal sperm parameters based on WHO 2000 criteria (concentration⩾ 15 million/mL, motility A+B ⩾ 32%, normal forms ⩾ 4%).
  • Ability to have regular intercourse during the study
  • No previous sterilization procedures (vasectomy, tubal ligation) that have been reversed

Candidates will be excluded from the study if ANY of the following conditions apply:

  • Pregnant, parturient or breastfeeding women
  • Marked obesity, BMI > 35
  • Marked hyperandrogenism (FAI > 15)
  • Previous ovarian surgery: LOD, endometriosis surgery, ovarian cysts surgery, patients with known or suspected periovarian adhesions.
  • Subject with pacemaker, defibrillator or other active implant
  • Subject is currently participating in another investigational drug or device study that clinically interferes with the endpoints of this study
  • Lack of capacity to give informed consent (individuals deprived of their liberty subject to a legal protection measure or who are unable to express their consent, individuals under guardianship or curatorship)

Treatment and study plan

May Health Kit

Device

The intervention consists in the realisation of the May Health Procedure using the May Health Kit, which comprises two elements: a disposable device (May Health Device) and a radiofrequency (RF) energy generator (May Health System). The May Health Device is a short-term invasive device delivered and positioned through the vagina to deliver RF energy inside the ovary in order to ablate ovarian tissue.

Primary outcomes

  1. Adverse Events (AEs) in terms of type (device/procedure related), seriousness, level of severity. Rate of occurence of intra-procedural and post-procedural adverse events, and device related complications

    Time frame: Up to 30 days

  2. Successful completion of a complete ovarian tissue ablation procedure, which is defined as achievement of the desired number of ablations within each ovary under ultrasound visualization.

    Time frame: During procedure

Secondary outcomes

  1. Occurrence of ovulation following the procedure

    Time frame: Up to 3 months after procedure

Other outcomes

  1. Pain level using the Visual Analogue Scale (VAS - 0 : no pain - 10 : worse pain possible), record of pain medications with doses administered during procedure

    Time frame: At procedure, 7 days, 30 days

  2. Usability of the May Health Kit

    Time frame: During procedure

  3. Pain level using the Visual Analogue Scale (VAS - 0 : no pain - 10 : worse pain possible), record of pain medications with doses administered post-procedure

    Time frame: At 30 days

  4. May Health Procedure time

    Time frame: During procedure

  5. Occurrence of ovulation following the procedure

    Time frame: Up to 6 months after procedure

  6. Pregnancy

    Time frame: At 3, 6, 9 12 and 24 months
