Endometrial thickness during ovulation is one of the important indicators for monitoring female fertility. During ovulation, the lining of the uterus becomes softer and easier to absorb the implanted material. If the endometrium is too thin or too thick, it may cause difficulty in embryo implantation, thus affecting a woman's fertility.

However, measuring endometrial thickness requires accurate B-ultrasound equipment and good operating techniques. If the B-ultrasound equipment is inaccurate or the operation technique is improper, it may lead to large errors in the measurement results. Therefore, before taking measurements, it is recommended that women consult a professional B-ultrasound doctor and ensure the quality and operating techniques of the B-ultrasound equipment.

In addition to measuring endometrial thickness during ovulation, women can monitor their fertility through other methods. For example, a woman's fertility can be assessed by measuring the length and regularity of her menstrual cycle, as well as by measuring markers of her fertility such as ovarian reserve.

In summary, measuring endometrial thickness during ovulation is one of the important indicators for assessing female fertility. If a woman's endometrium is too thin or too thick, it may make it difficult for the embryo to implant, thus affecting the woman's fertility. Therefore, it is recommended that women undergo regular B-ultrasound examinations and follow the advice of professional doctors to ensure that their fertility is normal.
