Intracytoplasmic Sperm Injection ICSI is performed as an additional part of an IVF treatment cycle where a single sperm is injected into each egg to assist fertilisation using very fine micro-manipulation equipment. In most cases, ICSI can be used to overcome severe male infertility. We can also use this technique for couples who have experienced poor or no fertilisation rates using standard IVF. Since it was introduced, it has led to the birth of many thousands of babies worldwide that otherwise might not have been conceived. While success rates can give you an indication of your chance of conceiving they are not specific to your situation.

Expression of the cell cycle in sperm of Arabidopsis: implications for understanding patterns of gametogenesis and fertilization in plants and other eukaryotes. Sperm of Arabidopsis rapidly enter the S synthesis phase of the cell cycle after inception from mitosis of the generative cell. Sperm in pollen grains within anthers continue to synthesize DNA, and at the time of pollination, contain approximately 1. Following pollination, sperm continue through the S phase of the cell cycle during pollen tube growth.
