In 2022, SPZ Lab got a new logo, which is an illustration of a zygote – the initial stage of the fertilised egg before it divides for the first time.
The traditional logo for ‘fertility’ is a sperm cell that is about to fertilise an egg. However, the latest research shows that the biggest challenge is not fertilisation at all, which means the traditional view is a bit ‘outdated’.
Unless the quality of the man’s sperm is extremely poor, the vast majority of eggs are fertilised. The big challenge does not emerge until after fertilisation has been completed.
Research shows that if you have zygotes from 100 completely normal couples (without fertility problems), only 40% to 60% of them will be able to develop into babies. In approximately half of the cases, the development of the zygote/embryo/foetus will come to a halt at some point (Jarvis 2020).
If the embryo dies before it can attach itself to the uterus, the pregnancy will not occur.
If it attaches itself to the uterus but subsequently dies, the couple will experience a spontaneous miscarriage.
