Why Pregnancy Doesn't Happen Even When Timing Intercourse Around Ovulation: The Real Reasons

Many couples waiting for a baby try desperately around ovulation time, only to be exhausted by recurring disappointments. They often fall into self-blame: 'Is there something wrong with me?', 'Am I not trying hard enough?'. However, pregnancy is not determined solely by ovulation and intercourse. It is because new life can only take root when the complex systems in our body work in harmony. Dalimchae Oriental Medicine Clinic Incheon branch receives many visitors with these concerns.

💡 [Key Answer] The 3 most common causes of the question "Why pregnancy doesn't happen": ① Uterine and ovarian function decline / ② Unstable implantation environment / ③ Unexplained infertility Dalimchae Oriental Medicine Clinic creates a body where pregnancy happens easily through fundamental constitutional improvement.

Pregnancy goes beyond sperm and egg meeting for fertilization; the entire process where the fertilized egg successfully implants in the uterus and is stably maintained is crucial. Ovulation is just the beginning of this process, and several factors that many easily overlook affect pregnancy success rates.

First, decline in uterine and ovarian function. Even with regular ovulation, egg quality may drop or ovarian function may weaken, preventing healthy follicles from growing. Also, if the uterus is cold or blood circulation is poor, the endometrium may not thicken sufficiently, causing difficulty in implantation. In Oriental medicine, this is viewed as uterine cold syndrome (子宮寒證) and interpreted as an environment unsuitable for pregnancy.

Second, instability of the implantation environment. No matter how healthy the fertilized egg is, if the endometrium is not ready to accept it, implantation easily fails. If endometrial thickness or receptivity is poor, or due to immunological issues where the fertilized egg is recognized as a foreign substance and rejected, rejection can occur. Repeated implantation failures bring great frustration to couples.

Third, unexplained infertility. This refers to cases where modern medical tests find no special abnormalities yet pregnancy does not occur. About 15% of all infertile couples fall into this category, and invisible functional imbalances are often the cause. Stress, lifestyle habits, and autonomic nervous system disturbances can act complexly to hinder pregnancy. In particular, many couples visiting Incheon infertility Oriental clinics experience such unexplained infertility.

If 3 or more of the following symptoms apply, you may be experiencing unexplained infertility or difficulties preparing for pregnancy. Check your body condition and consider expert help.

• Menstrual cycles are irregular or menstrual pain is severe.
• Menstrual flow is too little or too much, with clotted blood.
• Hands, feet, or lower abdomen are always cold.
• Feeling chronic fatigue and lethargy.
• Vulnerable to stress, sensitive, and experiencing severe mood swings.
• Frequent digestive problems, constipation, or diarrhea.
• Suffering from immune system diseases such as skin troubles or allergies.
• Past history of miscarriage or multiple implantation failures.
• No natural pregnancy for over 1 year without a special disease.

If 3+ apply: Suspected uterine and ovarian decline → Consider complex Oriental medicine treatment. If 5+ apply: Immediate visit and expert Oriental medicine consultation recommended.

Many struggling with infertility wonder about the effectiveness of Oriental medicine treatment. Recent domestic and international studies continue to report that Oriental medicine treatment has a positive effect on infertility, especially unexplained infertility and repeated implantation failures.

In a 2021 multicenter study by Dong-il Kim's research team published in the journal 'Integrative Medicine Research', 90 women with unexplained infertility received herbal medicine (Onkyeong-tang and Ovulation Implantation Formula) and acupuncture treatment for 4 months, resulting in a Clinical Pregnancy Rate (CPR) and Implantation Rate (IR) of 14.44%. This is similar to or higher than the 13.6% artificial insemination pregnancy rate for unexplained infertility in the 2016 government infertility support project. The researchers concluded that Oriental medicine treatment offers the possibility of pregnancy success and safety for women with unexplained infertility. These data suggest new hope for couples suffering from infertility.

Additionally, in a 2025 prospective multicenter observational study by Min-hee Kang's research team published in the journal 'Hindawi', a total of 96 infertility patients from 6 Korean medicine hospitals and 42 Korean medicine clinics in Korea were analyzed. In this study, applying Oriental medicine treatments including acupuncture and herbal medicine (especially Jokyeong-jongok-tang) for an average of 104.7 days showed a clinical pregnancy rate of 20.8% (95% CI, 13.9–30.0%) and a live birth rate of 13.5% (95% CI, 8.1–21.8%). The researchers noted that although it is a small-scale study, it provides important insights into the characteristics, treatment patterns, clinical results, and safety of Oriental medicine infertility treatment.

These research results go beyond mere statistical figures, supporting the importance of the fundamental constitutional improvement treatment aimed at by Dalimchae Oriental Medicine Clinic. Correcting body imbalances and creating a body state optimized for pregnancy is ultimately the core of overcoming infertility.

Dalimchae Oriental Medicine Clinic Incheon branch focuses not only on 'inducing' pregnancy, but on 'rebuilding' the healthy state of the body so that pregnancy can be achieved naturally. We call this constitutional improvement. Rather than temporarily turning off symptoms, it is managing the root cause so that the body turns on its own pregnancy ability again and that ability is sustained.

By carefully diagnosing each patient's constitution and current body condition, we optimize all elements necessary for pregnancy, such as strengthening ovarian function, improving uterine environment, regulating hormone balance, and relieving stress. For example, for those who have difficulty with implantation due to a cold uterus, we prescribe treatments to warm the uterus and aid blood circulation; for those with poor egg quality, we provide treatments to restore ovarian function and help egg maturation.

Through herbal medicine prescriptions and acupuncture treatments, we smooth overall Qi and blood circulation in the body and restore the balance of the autonomic nervous system disturbed by stress. This process helps the body return to the optimal state for healthy pregnancy. In particular, even in the Incheon infertility preparation process before and after IVF procedures, parallel treatment can help increase implantation success rates and prevent miscarriages. Since infertility is not just a woman's problem but men's health is also important, we focus on the process of couples creating healthy bodies together.

Q. Can unexplained infertility also be treated with Oriental medicine? A. Yes, it is possible. Unexplained infertility refers to cases where modern medical tests find no special abnormalities, and Oriental medicine treats it by focusing on functional imbalances. Through uterine environment improvement, ovarian function enhancement, hormone regulation, and systemic health promotion, it helps induce natural pregnancy or increase the success rate of assisted reproductive technology.

Q. How long does infertility Oriental medicine treatment take? A. Treatment duration varies depending on individual constitution, infertility causes, and health status, but generally, 3 to 6 months of steady treatment is recommended. Since it is a process of inducing fundamental changes in the body, it is important to take sufficient time for treatment, and Dalimchae Oriental Medicine Clinic Incheon branch establishes personalized treatment plans.

Q. Is it okay to combine IVF procedures and Oriental medicine treatment? A. Yes, parallel treatment can be very effective in increasing pregnancy success rates. Oriental medicine treatment thickens the endometrium, improves blood flow, enhances egg quality, and optimizes the implantation environment. Also, by reducing physical burden caused by stress and superovulation, it helps increase IVF success rate and prevent procedure side effects.

Q. What should I do if I get pregnant while taking herbal medicine? A. Dalimchae Oriental Medicine Clinic's infertility treatment herbal medicine is formulated so that it can be safely taken during pregnancy as well. Many prescriptions include Antae-eum (安胎飮) ingredients that prevent early miscarriage and stabilize the fetus. Upon confirming pregnancy, you can consult medical staff to adjust prescriptions or transition to Antae medicine for maintaining pregnancy and fetal health.

Pregnancy not happening? This worry is not a problem solved by enduring. You no longer need to ignore the body signals sent for a long time. Approaching in the right direction makes the body react faster than you think. Bring the symptoms you are experiencing as they are. Dalimchae Oriental Medicine Clinic will find the cause together.
