There is significant sperm loss after procreation sex. There are about hundred million sperms in an average ejaculate, and we need more than 2 million sperms to enter the cervix so that hundreds will reach the egg for fertilization to occur.
It is a common misconception that only a single sperm is needed for fertilization to occur.
In fact, the first sperm to reach the egg is never the one to fertilize it.
Hundreds of sperm are required to prepare the way for the final sperm 'survivor' to fertilize the egg.
These hundreds of sperm undergo acrosomal reaction, breaking down the outer two protective layers of the egg until a path is created to allow for the 'winner' to clinch the 'prized' egg.
In order to get a few hundred sperm reaching the egg, a few million sperm need to reach the uterus.
Most sperms do not remain in the vaginal tract right after sex.
Many of the sperm that remain in the vaginal tract will not survive the acidic environment of the vagina.
To make things worse, the average sperm count produced by men has halved within the last 40 years.
Therefore, achieving sufficient number of sperm reaching the uterus and the egg becomes more challenging today than ever before.
To address this need we designed the twoplus Sperm Guide. Made with a biocompatible, soft silicone, twoplus Sperm Guide has been designed to be used during intercourse to prevent semen leakage without compromising on comfort.
During intercourse, twoplus Sperm Guide’s soft but springy flap would allow the penis to effortlessly glide over the device. After ejaculation, the male withdraws and the twoplus flap springs up. This forms a seal that blocks the back-flow of semen. The twoplus Sperm Guide is designed to get as many sperms as possible to the right place in the vaginal tract. The device also protects the semen from the harmful acidic vaginal fluid secreted lower down in the vaginal canal.
