In our previous newsletter, we discussed the importance of the fertility laboratory in IVF and set out to begin describing some of the supplementary lab techniques used by embryologists. Last time, we spoke on the EmbryoScope® time-lapse incubator; in this instalment, we shall briefly look at ICSI.
Not all sperm are equal, and sperm quality has a significant impact upon embryo quality and successful implantation. Simply stated, a healthy sperm is better than an unhealthy one, and it is advisable to use only the former when fertilising an egg.
Modern sperm selection methods now allow embryologists to identify and segregate only the most vigorous sperm for just this purpose. One of these methods is intracytoplasmic sperm injection, or ICSI.
In classical IVF, sperm and egg are combined in a dish, and fertilisation is left to occur in the absence of human intervention. This requires a sizeable concentration of motile sperm and leaves much to nature. In ICSI, by contrast, a single, pre-selected and morphologically-superior sperm is injected directly into the egg. This enables embryologists to exert even greater influence over the fertilisation process and significantly improves the prospect of conception.
ICSI is just one of several lab techniques our embryologists employ to help you get pregnant. Contact us today to learn more.
