Suggest and explain assisted reproductive techniques which will help a couple to have children, where the female had a blockage in the fallopian tube and the male partner had a low sperm count.

Explanation

With special techniques called assisted repoductive technologies, infertile could be assisted to have children.
ART includes :
(i) In-Vitro Fertilisation (IVF) : It is transfer of an ovum collected from a donor into the fallopian tube of another female for fertilisation and further development.
(ii) Zygote Intrafallopian Transfer (ZIFT) : Ova from wife/donor (female) and sperms from husband/donor (male) are collected and are induced to form zygote under simulated conditions in laboratory. The zygote with upto 8 blastomeres is then transferred into the fallopian tube.
(iii) Intra Cytoplasmic Sperm Injection (ICSI) : Here the sperm is directly injected into the ovum.
