Infertile Ph.D.
to PherDal Founder

Dr. Jennifer Hintzsche, Ph.D.
Founder & CEO of PherDal

Dr. Jenn struggled to conceive for over a year before being diagnosed with unexplained infertility. Fertility specialists told her that expensive options were her only chance at becoming a mother.  Instead, Dr. Jenn took her fertility into her own hands.

After 16 months of infertility, Hintzsche and her husband Ryan, a mechanical engineer, invented The PherDal Kit and the PherDal tracking methodology. They used their now-patented medical device and method to conceive their daughter in just the second month of use.


Knowing she could help other people struggling with infertility, Dr. Jenn started PherDal (pronounced 'fertile' but spelled with a Ph.D.) to help others have an affordable and safe fertility option she was able to make for herself.  

Our mission is to empower women with the tools they need to understand their own fertility cycle and to provide them with the support they need to make informed decisions about their reproductive health. 

Our team of experts, led by Dr. Jenn, is here to support you with ovulation consulting so that you can more easily understand the science behind your cycle. All information and education, zero nosy medical advice.
