ICSI treatment for infertility has greatly enhanced the prospects of many hopeful couples who want to become parents. It's the best treatment option for treating male infertility. 

• You can benefit from ICSI if you have poor sperm - either poor motility, or a low count 
• If you have a zero sperm count ( azoospermia), the doctor can do ICSI for you with testicular sperm ( TESA, for men with non-obstructive azoospermia because of partial testicular failure) or with epdidymal sperm ( PESA, for men with obstructive azoospermia)
• The procedure is also useful in cases of men who need to use  frozen sperm ( which they had to freeze  prior to starting  cancer treatment) 
• If you have failed IVF because of total fertilisation failure, then ICSI is your best  option 
• ICSI is also routinely used for  women who need to use their frozen  eggs to have a baby 

ICSI can be expensive , but it's the most cost effective treatment for infertile men, as it maximise the chances of having a baby quickly.
