An ovulation blood test is a common way to test a woman's fertility. During ovulation, a woman's egg is released from the ovary and enters the fallopian tube, where it is ready to combine with sperm. If a woman releases an egg during ovulation, it has the potential to be fertilized and develop into a fetus. Therefore, blood tests can help women determine when they are ovulating so that they can better arrange sexual intercourse and increase the fertilization rate.

In addition to testing HCG levels, blood tests can also help women determine their egg count. During the ovulation period, the number of female eggs usually increases. If a woman can determine her egg number, she can better arrange sexual intercourse and increase the fertilization rate.

A blood test is a reliable way to determine when a woman is ovulating and to increase fertilization rates. If a woman releases eggs during ovulation, a blood test can be done to confirm their presence and to better schedule intercourse to increase fertilization rates.
