Yes, so, nice, nice question about how we think about the clinical outcomes of Ovaprene. And so the study that we have conducted today, that the post test study, which is the pre pivotal study, it uses a surrogate marker for contraceptive effectiveness. And so at this point in time, those are really the best data we can point to what we would expect Ovaprene to how we would expect it to perform. It uses the likely typically use effectiveness rates is what does that prove pivotal test study is predictive. And so when we look at the outcome of that study, and then we look at other contraceptive studies that have been published that has done the pre pivotal test study, and then it's gone on to one full pregnancy prevention, contraceptive effectiveness studies, the findings would be indicative of a product that should have a typical use effectiveness of 86% to 91%. So that's what just right below the range of hormonal methods, which are 91%, typical use effectiveness method. So that's what the PTT trial, the test trial that we ran would be predictive of. In terms of the actual pregnancy prevention rate, which by the way, effectiveness rate, which tends to be kind of the BBB is effectiveness rate is like the inverse of your . So, we will know that definitively once we conduct the clinical trial that we've been talking about the Phase 3 that based on the pre pivotal, that's the range that we would be predicting, based on this outcome. And for the non-hormonal methods, I should add, that would be quite promising. I mean, this is one of the reasons that there's so much interest by a variety of parties like there at the NIH and Ovaprene, it's because for the non-hormonal methods, apart from the intrauterine device, which is implanted, it's challenging to achieve that level of effectiveness. The only products that have ever historically done that are the diaphragms, they're the only product vaginal gels, the vaginal femicides do not have that level, they've got a 27 index. Condoms do not have that level, they do a little bit better, they're 82% effective. But so only diaphragms have been able to achieve it, but their . So the ability to achieve that kind of effectiveness level with them once a month products would be quite promising for the field. And we're certainly hopeful that that Ovaprene goal will deliver the way that the test study predicted.
