Great underwear, no matter the need.

I will start by saying I did not get these for fertility reasons. However, they are extremely comfortable and work great for every day use. I have worn them to work, sports games, hiking and more and they perform well across the board. I have big legs and they don't ride up while also keeping the boys comfy.

The boys are breathing

This underwear is fantastic. I've been wearing them for a few weeks now and am very happy. I feel like I'm going to knock up my wife just looking at her. Will be adding more to the dresser soon!

Perfect product! 5 Star

Simply the right option for everyone! Super comfortable making it the only underwear you’ll want to wear, plus it has such great benefits to give you peace of mind!

Fast delivery and true to size

Definitely worth the investment - 5/5 stars

My 3 pack came in the mail about 2 weeks ago and her and I have both love them. I am a loyalist when it comes to boxers, but these are the most comfortable I’ve ever worn which makes me very happy I bought them. The fabric feels great, super soft with a bit of stretch, and the athletic fit is perfect. Snug in all the right places without feeling tight and does not ride up at all.

They also look great - very flattering. Honestly, they’re the kind of boxers you don’t mind being seen in.

Worth the purchase, boys.

High quality undies

Really great product. Comfortable. Nice cool material. Couldn’t ask for more in my underwear

"I'm so happy I found this company. I didn't realize how much control I had over my fertility levels. I only wear boxer briefs and hate traditional boxers so these were perfect for me. Tight in the right spots and loose in the right spots."

"These are extremely comfortable. The starter kit is great and the order came with a great info card that tells you exactly what you need to go to increase your sperm count. Looking forward to taking my next sperm test to see how much I improved."
