Is a behavior in mating in which one male breeds with a female for a certain period of time and then finds a different mate the following mating season

i thinking chemical change

i think that it is plants

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
