Fertilisation in humans is practically feasible only if:
| 1. | the ovum and sperms are transported simultaneously to the ampullary-isthmic junction of the fallopian tube. |
| 2. | the ovum and sperms are transported simultaneously to the ampullary-isthmic junction of the cervix. |
| 3. | the sperms are transported into the cervix within 48 hrs of the release of the ovum in the uterus. |
| 4. | the sperms are transported into the vagina just after the release of the ovum in the fallopian tube. |
Ectopic pregnancies are referred to as :
| 1. | pregnancies with a genetic abnormality |
| 2. | implantation of the embryo at a site other than the uterus |
| 3. | implantation of a defective embryo in the uterus |
| 4. | pregnancies terminated due to hormonal imbalance |
