A couple are not able to conceive . After tests it is discovered that the uterus of woman is healthy but she has blocks in the fallopian tubes. Which of the following ARTs can be suggested by the Doctor?

As fallopian tubes are blocked, transfer of zygote to it cannot lead to implantation. So, ZIFT is rules out.AI is artificial insemination. It requires ovum to be produced by woman but transport of ovum cannot happen due to blocked fallopian tubes.GIFT is gamete intra fallopian transfer which is suggested when woman cannot produce ovum. Although ovum is transferred to fallopian tube, the blockage of it would not lead to conception.
