In case of a couple where the male is having a very low sperm count, which technique will be suitable for fertilisation?

For cases of low sperm count (oligospermia) or inability of the male to inseminate, Artificial Insemination (AI) is used. Semen is collected and introduced artificially into the vagina or uterus (IUI) of the female. (ICSI is also used, but AI is the primary treatment listed for simple low count in this context).
