Oligospermia is a low count of sperm count per ejaculate. It can be mild, moderate and severe.Due to ART's (Assisted reproductive technologies) such a male too can overcome its infertility. Two important techniques are ZIFT and ICSI. ZIFT is a zygote intrafallopian transfer. In this technique the sperms and eggs are fertilised in test tubes and then the zygote is transferred into the uterus. This prevents wastage of sperms and increases the chances of fertilisation.The other technique suitable incase of oligospermia is ICSI (Intracytoplasmic sperm injection). In this sperms are directly injected inside the ovum to avoid wastage.
