If the water concentration inside a cell is higher than the water concentration outside the cell, water flows out of the cell. this method of molecular transport is called

Exosmosis

Explanation:

Osmosis is the process of movement of water down the concentration gradient across a semi permeable membrane. Exosmosis is movement of water outside the cell through osmosis. Here, the water movement is shown to occur from the region of its higher concentration (inside the cell) to that of lower concentration (outside the cell). Plasma membrane serves as semi permeable membrane. So, the process is called as "exosmosis" with respect to cell.

the answer to your question is sperm

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 : )
