Question : How many normal sperm are required for IVF?

Answered by Dr. Sree Gouri SR (5 hours later)

Hi,
Thanks for the query.

Usually around 50,000 spermatozoa are required to fertilize one ovum.
So around 4 to 5 million spermatozoa are required for IVF.
In them at-least 30% should be motile and 15% should have progressive motility.
And minimum 20% spermatozoa should have normal morphology.
Minimal deviation from the normal range can also be accepted sometimes.
Hope I have answered your query. I will be available to answer your follow up queries. If you are satisfied with all my answer, please rate the answer after closing the discussion.
Take care.
