9. Human implantation occurs

a. During the estrogenic phase of the uterine cycle

b. During the secretory phase of the uterine cycle

c. During the fourth week of development

d. a and b

e. none of the above

Expert Solution

Ans:- none of the above.

because implantation OCCURE between day 5- 12 after fertilisation.

i.e after 1-2weeks of fertilisation.

Note:- Actually there is a controversy .

if we will take 1st day of last menstruatral period as intial day of development then implantation occur at 3rd -4th week.

but if we will take the day of fertilisation as 1st day of development then implantation will OCCURE at 5-12 th day .
