Question

The role of the corpus luteum and the hormones it produces ends

• A. at the time of embryonic implantation in the uterus
• B. With the formation of the placenta
• C. during the second trimester of pregnancy
• D. just prior to parturition

Answer 1

The correct option is A at the time of embryonic implantation in the uterus

Corpus luteum is the remnant of the graffian follicle after ovulation completes.

Corpus luteum releases progesterone which is very important for pregnancy to occur.

It maintains and develops the uterine wall in case fertilisation and implantation of embryo occurs.

Corpus luteum has it's function much before the formation of placenta in the extreme early phase of pregnancy.

So the correct answer is ' At the time of embryonic implantation in the uterus'.
