B-ultrasound ovulation period refers to measuring the production and maturation time of eggs in women through ultrasound examination. It is a very important fertility indicator. Women begin producing eggs on day 14 of their menstrual cycle and end on day 28. During this time, the egg matures and awaits fertilization by sperm.

By measuring ovulation through B-ultrasound, doctors can determine whether a woman's eggs have matured and whether they still have enough energy to fertilize. This can help couples better plan their fertility and avoid fertilizing eggs when they are about to mature or are already mature, leading to unnecessary fertility risks.

B-ultrasound measurement of ovulation is a very useful tool that can help couples better plan their fertility. With accurate measurements, doctors can better determine whether a woman's eggs are mature, helping couples better plan their fertility and reduce unnecessary fertility risks.
