Outcome Measures
Primary Outcomes (2)
Ovulation occurrence
Occurrence of at least one (1) ovulation
3 month follow-up
Adverse event collection
Adverse events will be collected between and at each study visit after randomization and throughout the duration of the study and analyzed for seriousness, severity, relatedness to the device and/or the procedure, and whether anticipated
Day 0 through 36 month visit
Secondary Outcomes (10)
Cumulative ovulation rate at 6 months without 1st-line medication
Device arm and Crossover at 6 month visit
Cumulative ovulation rate at 6 months with 1st-line
Device arm and Crossover at 6 month visit
Time to ovulation
Baseline for the control group is day of randomization to the date of first ovulation. Baseline for the treatment group is day of procedure to the date of first ovulation
Documented pregnancy
Control Arm, Device Arm, and Crossover group: from baseline to 30 Day, 3 Month; Device Arm and Crossover group only: 6 Month, 12 Month, 24 Month, 36 Month
Hormone serum concentrations
Baseline through 36 month visit
- +5 more secondary outcomes
Study Arms (2)
Device arm
EXPERIMENTALMay Health procedure performed with the use of the May Health system intended for transvaginal ablation of ovarian tissue under ultrasound visualization in women with infertility due to Polycystic Ovary Syndrome.
Control arm
NO INTERVENTIONNo fertility medication. Crossover participants who choose to crossover after the 3 month follow up visit will restart follow up as per the Device arm.
Interventions
The intervention includes the short-term use of the May Health System, which is comprised of three elements: (1) the May Health Needle-Catheter Ablation Device (NCAD) (the Device) a 16 gauge echogenic needle including a bipolar temperature-controlled RF ablation catheter which is clipped and secured onto a vaginal ultrasound probe; (2) the May Health Adapter which is clipped onto the ultrasound probe; and (3) the May Health Generator: a bipolar radiofrequency (RF) ablation platform utilizing the single use May Health NCAD for ovarian tissue ablation. Once the patient is under conscious sedation, the physician guides the May Health system transvaginally with the use of a transvaginal ultrasound. Once the May Health device is safely and securely positioned, the physician will deliver radio frequency energy inside the ovary in order to ablate the tissue.
Eligibility Criteria
You may qualify if:
- Age ≥ 18 to ≤ 40 years
- Infertility associated with oligo- or anovulation, AND EITHER:
- Ultrasonographic evidence of PCOS (ovarian volume ≥ 10 mL and/or ovarian antral follicle count per ovary ≥ 20) OR
- Evidence of hyperandrogenemia: either clinical (hirsutism defined as modified Ferriman-Gallwey (mFG) level ≥ 4-6 depending on ethnicity) or biochemical (raised serum concentration of androgens, testosterone ≥ 2.5 nmol/L, or FAI \> 4)
- At least one ovary with ovarian volume ≥ 10.0 mL and \< 28.0 mL
- Ovarian accessibility: determined by ability to bring transvaginal ultrasound transducer into close proximity to at least one ovary. (Note: In the situation where only one ovary is appropriately sized according to the preceding criterion, then this requirement applies to the qualifying ovary.)
- At least one patent fallopian tube and normal uterine cavity as determined by sonohysterogram, hysterosalpingogram, or hysteroscopy/laparoscopy within the last 3 years
- Has not responded to first-line ovulation induction treatment or is contraindicated for, or declines, such treatment
- Currently seeking immediate fertility
- Willing to comply with Clinical Investigation Plan-specified follow-up evaluations
- Ability to understand study requirements and has sufficient fluency in one of the approved written translations of the Patient Information and Informed consent form
- Signed informed consent
You may not qualify if:
- Currently pregnant
- BMI \> 40
- Marked hyperandrogenism (total serum testosterone ≥ 4.5 nmol/L or 130ng/dL)
- Poor glycemic level control defined as glycohemoglobin (HbA1c) level \> 6.5%
- Bleeding disorders, such as von Willebrand disease, thrombocytopenia, current use of anticoagulation medication, etc.
- Active genital or urinary tract infection at the time of the procedure
- Patient with known or suspected periovarian adhesions
- Previous ovarian surgery (e.g. ovarian drilling, ovarian cysts surgery, or endometriosis surgery on the ovary)
- Transvaginal ultrasound transducer cannot be brought into proximity of at least one ovary
- Presence of a pathologic cyst (i.e. endometrioma, dermoid, etc.) of any size, or a follicle, or functional cyst \>15 mm on transvaginal ultrasound in ovary to be treated
- Received \> 2 cycles of treatment with gonadotropins for ovarian stimulation without a resulting pregnancy (excludes human chorionic gonadotropin (hCG) trigger injection)
- Contraindicated to or known previous reaction to anesthesia or sedation regimen
- Patient not willing to stop all concomitant first-line ovulation induction treatment (clomiphene citrate, letrozole, as well as metformin unless metformin is required for glycemic control) until the 3-month endpoint is reached
- Male partner's total motile sperm count (TMSC) \< 10 million or not available (unless participant is planning donor sperm IUI)
- Patient is currently participating in another investigational drug or device study that clinically interferes with the endpoints of this study
- +2 more criteria
