What are the reasons for not getting pregnant during the ovulation period?

Generally, failure to conceive during the ovulation period may be caused by errors in determining ovulation timing, inappropriate timing of sexual intercourse, polycystic ovary syndrome, endometriosis, fallopian tube blockage, and other factors. It is recommended to seek timely medical consultation to identify the exact cause and receive appropriate treatment under a doctor's guidance. Detailed explanations are as follows:

1. Ovulation timing errors: Estimating ovulation time based on the menstrual cycle can easily lead to inaccuracies, resulting in intercourse not occurring around the actual ovulation day, which affects conception. Ovulation test strips can be used to monitor the LH surge, ultrasound can track follicular development, or cervical mucus changes can be observed to accurately determine ovulation timing and increase the chances of conception.

2. Inappropriate timing of sexual intercourse: Although during the ovulation period, if the frequency of intercourse is too low or does not occur within the egg's viable period, sperm may be unable to meet the egg. It is recommended to maintain intercourse every 1-2 days starting three days before ovulation and continuing one day after, to ensure that sperm and egg have the opportunity to meet.

3. Polycystic ovary syndrome (PCOS): Endocrine disorders lead to poor follicular development and lack of mature eggs being released, affecting conception. This is often accompanied by irregular menstruation and hirsutism. Patients should follow medical advice to use medications such as clomiphene citrate tablets, letrozole tablets, progesterone soft capsules, etc., to promote ovulation, regulate menstruation, and improve ovulatory function to increase the chances of conception.

4. Endometriosis: Ectopic endometrium can affect ovarian function, interfere with fallopian tube motility, or cause pelvic adhesions, hindering conception, often accompanied by dysmenorrhea and dyspareunia. Follow medical advice to use medications such as gestrinone capsules, danazol capsules, dydrogesterone tablets, etc., to inhibit the growth of ectopic endometrium.

5. Fallopian tube blockage: Inflammation-induced adhesions or fluid accumulation in the fallopian tubes can cause blockages, preventing sperm and egg from meeting and hindering the transport of the fertilized egg. Mild blockages can be treated with anti-inflammatory medications such as cefuroxime axetil tablets, metronidazole tablets, azithromycin dispersible tablets, etc., under medical guidance. Severe blockages may require procedures such as tubal irrigation or tubal ostomy to restore patency.

In daily life, maintaining a regular routine, avoiding late nights, reducing mental stress, and maintaining emotional stability are important. Nutritionally, a balanced diet with adequate intake of vitamins and minerals, avoiding excessive dieting or overeating, helps provide a healthy physical foundation for conception.
