Verified step by step guidance

1. Step 1: Understand the term 'ectopic pregnancy' which refers to a pregnancy where the fertilized egg implants outside the uterus.
2. Step 2: Recognize that the fallopian tube is the most common site for ectopic pregnancies.
3. Step 3: Break down the medical terms: 'Salpingo-' refers to the fallopian tube, and '-cyesis' means pregnancy.
4. Step 4: Combine the roots to identify that 'Salpingocyesis' means pregnancy occurring in the fallopian tube.
5. Step 5: Review the other options: 'Hematosalpinx' refers to blood in the fallopian tube, 'Salpingogravida' is not a standard term for ectopic pregnancy, and 'Dystocia' means difficult labor, so they do not fit the definition.
