Fertility Control

Contraceptive Status of Women in the US: 47 million women aged 15-49 in the U.S. are currently using contraception; clinicians have seen a rise in patients seeking consultation for conception over recent years.


Uterine fibroids are estimated to be the most common benign pelvic tumors in women, impacting approximately 20-30% of women by the time they reach menopause.


Overview: ~7.3 million, or about 10%, of women of reproductive age in the U.S., have endometriosis and ~5.5 million or ~75%, are symptomatic.

Hormone Replacement Therapy

Vulvovaginal Atrophy (VVA) Overview: VVA is associated with decreased estrogen that affects ~50% of post-menopausal women (~31.1M women in the U.S.), but only half consult their physician for VVA symptoms.

1. Overactive Bladder

  • Overactive Bladder affects ~21 million women in the U.S., but only 45% seek treatment.
  • OAB is a syndrome defined by frequent and sudden urges to urinate that is difficult to control.
  • OAB is caused by involuntary movement of the bladder muscles even when urine volume is low, which causes the urgent need to urinate.



  • Inhibition of Leukemia Inhibitory Factor (LIF) can serve as a potential future anti-tumor treatments for Triple Negative Breast Cancer, Ovarian Cancer, and Pancreatic Cancer. LIF is a pleiotropic protein that belongs to the interleukin – 6 family cytokines and is necessary for maintaining the pluripotency state of embryonic stem cells and induced pluripotent stem cells.
