Fertilisation in humans is practically feasible only if

1. the ovum and sperms are transported simultaneously to ampullary-isthmic junction of the fallopian tube
2. the ovum and sperms are transported simultaneously to ampullary-isthmic junction of the cervix
3. the sperms are transported into cervix within 48 hrs of release of ovum in uterus
4. the sperms are transported into vagina just after the release of ovum in fallopian tube
