Question

Explain why only one corpus luteum may be found in the ovaries of a woman who has given birth to triplets.

Answer 1

I don't know if you are using several screen names or not, but here is my answer to the same question from a later post.

If the triplets came from one corpus luteum, they would be identical rather than fraternal. Identical siblings come from one fertilized egg that splits, one time or more.

Fraternal siblings come from coincidental, separate fertilizations, meaning that more than one egg was ovulated, which requires more than one corpus luteum in the ovaries.

I hope this helps. Thanks for asking.
