Cycle of sperm

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.

According to an article published in the journal Annals of Oncology , men with early stage testicular cancer Testicular Cancer in Clinical Stage I, or TC CS I can be treated with one course of chemotherapy or radiotherapy after surgery without long-term effects on their sperm count. Testicular cancer is the most common cancer among young men between the ages of 15 and 40, and when it is diagnosed, all patients have the testicle containing the tumor removed, and that surgical procedure is called orchiectomy. The recurrence after the removal of the tumorous testicle decreases.
