Another reasons for using ICSI

Although the ICSI technique is usually recommended for men with a severe male factor, there are other situations where it is also a good option. Among them are the following:

• Frozen sperm sample before starting an oncological treatment, either radiotherapy or chemotherapy.
• Low ovarian reserve in women.
• Ova with thickened zona pellucida.

However, there is no exact rule, but it is important to know each particular situation in order to evaluate the best fertility treatment.
