The reasons behind this may involve physical, psychological, environmental and other factors. This article will combine recent hot topics and data across the Internet to provide you with a structured analysis of the common causes of infertility during ovulation and provide scientific advice.

2. 6 main reasons for not conceiving during ovulation
1. Error in judging ovulation
About 32% of women trying to conceive have errors in ovulation calculation. Common misunderstandings include: relying solely on the calendar method (error ±3 days), ignoring individual cycle differences, and not combining scientific methods such as basal body temperature or ovulation test strips.
| Detection method | Accuracy | Best time to use |
|---|---|---|
| basal body temperature method | 76% | before getting up in the morning |
| Ovulation test strips | 89% | Menstruation begins on day 10 |
| B-ultrasound monitoring | 98% | Menstrual cycle day 12 |
2. Sperm quality issues
The latest standards of the World Health Organization show that normal semen parameters have been adjusted to: concentration ≥ 15 million/ml, forward motility sperm ≥ 32%. Factors such as staying up late for a long time, high temperature environment, smoking and other factors can reduce sperm quality by more than 40%.
3. Fallopian tube factors
About 25% of infertility cases are related to fallopian tube blockage. Patients with a history of pelvic inflammatory disease and endometriosis have a 3-5 times increased risk and need to be diagnosed by fallopian tube angiography.
4. Endometrial receptivity
During the implantation window period (6-10 days after ovulation), the endometrium thickness should reach 8-12mm. The latest research found that 67% of patients with repeated implantation failures had abnormal endometrium gene expression.
5. Endocrine disorders
Abnormal thyroid function (TSH>2.5mIU/L) and elevated prolactin (>25ng/ml) can interfere with ovulation. The rate of ovulation failure in patients with polycystic ovary syndrome is as high as 70%.
6. Immune factors
About 10% of unexplained infertility is related to anti-sperm antibodies, which can reduce sperm survival rate by more than 50%.
3. Action Guide for Scientific Preparation for Pregnancy
| Time node | female measures | male measures |
|---|---|---|
| 3 months before preparing for pregnancy | Supplement folic acid 400μg/day | Quit smoking and drinking |
| 5 days before ovulation | Monitor LH spikes daily | Avoid saunas |
| Ovulation period | Roommate every other day | Reduce strenuous exercise |
| after ovulation | Maintain a normal routine | Supplement zinc and selenium |
4. When do you need medical treatment?
According to the recommendations of the American Society for Reproductive Medicine, couples under the age of 35 who have had regular intercourse without pregnancy for one year, or those over the age of 35 who have not become pregnant for six months, should undergo a systematic check-up in a timely manner. Focus on:
• Women: Six items of sex hormones (2nd-3rd day of menstruation), AMH test, fallopian tube patency test
• Male: Semen routine (abstinence for 3-7 days) + sperm DNA fragmentation rate test
5. Latest Fertility Research Trends
The 2023 journal Human Reproduction pointed out that the clinical pregnancy rate of women with vitamin D levels ≥30ng/ml has increased by 33%. It was also found that the Mediterranean dietary model can increase the chance of conception by 40%.
Preparation for pregnancy is a systematic project that requires the participation of both husband and wife. Maintain an optimistic attitude, follow scientific methods, and seek help from professional reproductive doctors if necessary to improve the success rate of conception.
