Benjamin Tee
Co-Founder, twoplus fertility

Dr.Benjamin Tee started twoplus fertility after he and his wife faced challenges conceiving after several years. Like many couples, Ben and his wife were very excited to start a family together after spending time on their careers. However, the longer the process took, the greater the frustration became for them. Fertility doctors had diagnosed them with unexplained infertility.

As a scientist with a PhD from Stanford University and a Stanford Biodesign Fellow, Ben decided to channel his frustrations to understanding fertility and conception. He was frustrated by the lack of good and credible home-based solutions for couples that preserved the privacy of the process. He wanted this to change.

After developing a good understanding of fertility through researching this space and speaking with top fertility scientists and clinicians, Ben teamed up with a couple of engineers to start twoplus fertility. They aim to look for ways to improve the likelihood of conception for couples anywhere in the world.

twoplus fertility’s approach is simple: “We want to build products that couples like Ben and his spouse would use.”

Our first product, the twoplus sperm guide, focuses on a key aspect of natural fertility: improving sperm transport for fertilization. Men of this generation carry about half the number of sperms compared to men from 40 years ago(1). Coupled with the fact that most sperm don’t make it very far into the female reproductive tract(2), the twoplus sperm guide is designed to get as many sperm as possible to the right location within the vaginal tract for conception.

The team took over two years to develop the technology behind twoplus sperm guide. The process had been long and arduous. However, it was all worth the effort when twoplus welcomed the first baby born using its technology. Having hit that milestone, Ben now wants twoplus to aim higher: “We want to help 1 million couples conceive over the next 10 years.”
