Polycystic ovary syndrome (PCOS) is a leading cause of female infertility worldwide. Doctors diagnose it from ovarian signs such as cysts, irregular or missing menstrual cycles, and high levels of male-type hormones (androgens).

What they work on

  1. Test whether estradiol and progesterone fail to suppress KNDy neuron activity in prenatally androgenized PCOS model mice, using in vivo calcium imaging of individual neurons in freely behaving animals alongside LH pulse measurements.
  2. Identify where the lost GABAergic (inhibitory) inputs to KNDy neurons come from in PCOS model mice, using retrograde monosynaptic rabies tracing, which labels the neurons wired directly onto a target cell.
  3. Determine how GABAergic inputs shape KNDy cell activity in fertile mice by switching their axon terminals on or off with light (optogenetics) while imaging KNDy calcium activity.
  4. Test whether chronic chemogenetic inhibition of KNDy neurons, using an engineered receptor activated by a drug, corrects GnRH/LH pulse problems and restores fertility in PNA mice.

More about the research

Yet changes in the brain also play a significant role in how the syndrome develops. Normally, the brain releases reproductive hormones in regular pulses, and hormones made by the ovary feed back to slow those pulses. In PCOS, this feedback brake fails, and the pulses run too fast. Which brain cells lose their response to the brake is still unknown.

Why it matters

PCOS affects up to 13% of women of reproductive age globally, and it is a leading cause of infertility. Clinical studies are already testing drugs that block the neurokinin B receptor to calm KNDy cell activity in patients. By pinpointing which brain circuits go wrong, this work may help guide treatments and preventive measures aimed at the brain-based causes of PCOS.
