The math says that in procreative sex, there’s significant sperm loss. The Sperm Guide then helps retain maximum sperm throughout the vaginal tract, so more can reach the egg for fertilisation to take place.
Ensures visibility of device during intercourse and allows for easy removal.
The intricate surface features were specially designed to guide sperm towards the cervix, increasing the number of sperm entering the uterus.
The curvature of twoplus sperm guide allows semen to sit closer to the cervix, improving contact between sperm and cervical mucus.
It is a common misconception that only a single sperm is needed for fertilisation to occur.
In fact, the first sperm to reach the egg is never the one to fertilise it.
Hundreds of sperms are required to set the stage for the final, surviving sperm to clinch the ‘prized egg’. (Check out the Acrosomal Reaction diagram on the left!)
Back to the math: For that few hundred sperms to reach the egg, more than 2 million sperms need to enter the cervix. A round of ejaculate contains hundred million sperms on average.
Here’s where things get tricky. Most sperms that remain in the vaginal tract will not survive the acidic environment.
To make things worse, the average sperm count produced by men has halved in the last 40 years — the first stage of getting sufficient sperms into the vagina is already disadvantaged (remember the fertilisation process?).
The twoplus Sperm Guide is specifically designed to address this problem. Made with a biocompatible, soft silicone, it prevents semen leakage without compromising on comfort.
During intercourse, twoplus Sperm Guide’s soft, springy flap allows the penis to effortlessly glide over. After ejaculation, the male withdraws and the twoplus flap springs up. This forms a seal that blocks the back-flow of semen.
The device also protects the sperms from the harmful acidic vaginal fluid secreted lower down in the vaginal canal.
