Question

Fertilisation of sperm and evg occurs in the ampullary isthmus junction is it true or fse

Answer 1

Answer:

hii

your answer is here !

Explanation:

The ovum released by the ovary is also transported to the ampullary-isthmic junction where fertilisation takes place. Fertilisation can only occur if the ovum and sperms are transported simultaneously to the ampullary- isthmic junction. This is the reason why not all copulations lead to fertilisation and pregnancy.

Answer 2

Answer:

As mentioned previously, fertilization occurs in the ampullary segment of the fallopian tube. Transit time of the zygote from the ampulla to the ampulla-isthmic junction is approximately 30 hours, after which the zygote remains in the isthmus another 30 hours before resuming transit through the isthmus.
