The gel is liquefied within 20 to 30 minutes by enzymes from the prostate gland. This liquefaction is important for freeing the sperm so transportation may occur.

New study finds the egg may actually 'choose' the Sperm

Ovulation is a phase in the menstrual cycle. It occurs at about day 14 of a day menstrual cycle. However, during days 10 to 14, only one of the developing follicles forms a fully mature egg. At about day 14 in the menstrual cycle, a sudden surge in luteinizing hormone causes the ovary to release its egg.

The Punnett Square is a visual representation of Gregor Mendel's laws of inheritance.
