The fertile window refers to the days in a menstrual cycle when pregnancy is most likely to occur. Understanding this window can help couples better time intercourse when trying to conceive. In most menstrual cycles, ovulation occurs once per cycle when an ovary releases an egg. After ovulation, the egg typically survives for about 12–24 hours. However, sperm can survive inside the female reproductive tract for up to five days. Because of this difference, the fertile window usually includes the five days before ovulation and the day of ovulation itself. For example, in a typical 28-day cycle, ovulation may occur around day 14. The most fertile days would often fall between days 10 and 14. However, cycle length and ovulation timing can vary from person to person, and even from month to month. Many women track ovulation using signs such as changes in cervical mucus, ovulation predictor kits, or cycle tracking apps. Cervical mucus often becomes clearer and more slippery near ovulation, which may indicate that the body is entering its most fertile phase. Understanding the fertile window can help couples plan their timing more effectively when trying to conceive. Because every cycle can be slightly different, consistent tracking over several months may help provide a clearer understanding of individual patterns.

Many couples wonder how long they should try to get pregnant before seeking medical advice. The answer often depends on age and individual health factors.

In general, the commonly recommended timelines are:

• Under age 35: Try for about 12 months before seeking evaluation.
• Age 35–39: Consider seeking help after 6 months of trying.
• Age 40 or older: It may be helpful to speak with a professional earlier, since fertility naturally declines with age.

There are also situations where earlier evaluation may be helpful, including:

• Irregular or absent menstrual cycles
• Known conditions such as PCOS or endometriosis
• Previous pelvic infections or reproductive surgery
• Recurrent miscarriages
• Known male fertility concerns

Seeking advice does not necessarily mean starting complex treatments. Often, an evaluation simply helps identify possible factors affecting fertility and provides guidance on the next steps.

Understanding your reproductive health can help couples make informed decisions and reduce uncertainty during the process of trying to conceive.

In Taiwan, it is common for patients undergoing in vitro fertilization (IVF) to also receive care through Traditional Chinese Medicine (TCM) as part of their fertility management. Over the past several decades, Taiwan has developed a clinical environment where both Western reproductive medicine and Traditional Chinese Medicine are present in the treatment of infertility.

IVF procedures are performed by reproductive medicine specialists, while Traditional Chinese Medicine physicians assess patients based on their overall health status, reproductive history, menstrual health, and stage of fertility treatment. TCM places strong emphasis on individualized evaluation and treatment planning.

Traditional Chinese Medicine has historically been used in the management of women’s health, menstrual regulation, and infertility. In clinical practice, TCM is often used to help condition the body, support overall well-being, and maintain reproductive health during the fertility treatment process.

As fertility treatment often requires coordination between different healthcare providers, patients are encouraged to maintain open communication with their medical teams so that all aspects of care can be appropriately managed.

What is Low AMH?

Low AMH refers to a lower level of Anti-Müllerian Hormone, a hormone produced by small follicles in the ovaries. AMH is commonly used as a marker of ovarian reserve, which reflects the number of eggs remaining in the ovaries. When AMH levels are low, it may indicate a reduced ovarian reserve, meaning fewer eggs are available for potential ovulation.

Low AMH does not necessarily mean pregnancy is impossible, but it may suggest that fertility potential is declining, especially as age increases. Women with low AMH may experience fewer responding follicles during fertility treatments such as IVF, and it can sometimes be associated with irregular ovulation or earlier ovarian aging.

Doctors often evaluate AMH together with other tests such as follicle-stimulating hormone (FSH), ultrasound assessment of antral follicles, and overall reproductive history to better understand fertility potential.

Early fertility assessment can help individuals explore available options and plan appropriate strategies for conception. Even with low AMH, many women are still able to conceive with the right medical guidance and supportive care.

What is Male Infertility?

Male infertility refers to a man’s reduced ability to cause pregnancy in a fertile female partner. It is a common factor in fertility challenges and contributes to about 40–50% of infertility cases among couples trying to conceive.

The most common cause of male infertility is problems with sperm production or sperm quality. This may include low sperm count, poor sperm motility (movement), or abnormal sperm shape. These issues can make it more difficult for sperm to reach and fertilize the egg.

Several medical and lifestyle factors may affect male fertility. Hormonal imbalances, genetic conditions, infections, varicocele (enlarged veins in the scrotum), and certain medications can impact sperm production. Lifestyle factors such as smoking, excessive alcohol use, obesity, high stress levels, poor diet, and exposure to heat or environmental toxins may also affect sperm health.

A fertility evaluation for men usually includes a medical history review, physical examination, and a semen analysis to assess sperm count, movement, and structure. Additional hormone testing or imaging may sometimes be recommended.

With proper evaluation and supportive treatment, many men can improve their reproductive health. Addressing underlying medical conditions, improving lifestyle habits, and receiving appropriate care can help increase the chances of successful conception.

What is Recurrent Miscarriage?

Recurrent miscarriage, also known as recurrent pregnancy loss (RPL), is typically defined as the loss of two or more consecutive pregnancies before 20 weeks of gestation. It affects about 1–2% of couples who are trying to conceive and can be emotionally and physically challenging for those experiencing it.

There are many possible causes of recurrent miscarriage. Common factors include chromosomal abnormalities in the embryo, hormonal imbalances, uterine structural issues (such as fibroids or uterine septum), immune system disorders, blood clotting conditions, and certain lifestyle or metabolic factors. In some cases, however, no clear cause can be identified even after thorough medical evaluation.

A comprehensive assessment may include reviewing medical history, hormone testing, genetic screening, and imaging studies to evaluate the uterus. Identifying the underlying cause can help guide treatment strategies and improve the chances of a successful pregnancy.

Supportive care, lifestyle optimization, and individualized treatment plans are important for couples experiencing recurrent miscarriage. Some patients may also benefit from complementary approaches that focus on improving overall reproductive health, circulation, and hormonal balance.

If you have experienced multiple pregnancy losses, it is important to seek professional evaluation. Early assessment and personalized care can help identify potential factors and support a healthier path toward pregnancy.

What is Female Infertility?

Female infertility refers to the inability to conceive after 12 months of regular, unprotected intercourse. For women over the age of 35, infertility may be evaluated after 6 months of trying. It is a common condition and affects many couples worldwide.

There are several possible causes of female infertility. One of the most common is ovulation disorders, where the ovaries do not release eggs regularly. Hormonal imbalances, conditions such as polycystic ovary syndrome (PCOS), thyroid disorders, or elevated prolactin levels can affect ovulation and reduce the chances of pregnancy.

Structural problems in the reproductive system can also contribute to infertility. These may include blocked fallopian tubes, uterine abnormalities, fibroids, or endometriosis, which can interfere with fertilization or embryo implantation.

Age is another important factor. As women get older, both the quantity and quality of eggs gradually decline, which can make conception more difficult.

A proper fertility evaluation may include reviewing medical history, hormone testing, ultrasound imaging, and other diagnostic tests to better understand the underlying causes.

With appropriate evaluation and personalized care, many women with infertility can improve their chances of achieving a healthy pregnancy. Early consultation and supportive treatment strategies may help optimize reproductive health and fertility outcomes.

What is Endometriosis?

Endometriosis is a common condition in which tissue similar to the lining of the uterus grows outside the uterus. These growths may appear on the ovaries, fallopian tubes, or other pelvic structures. Because this tissue responds to hormonal changes each month, it can lead to inflammation, internal bleeding, and scar tissue formation.

Common symptoms include painful periods, chronic pelvic pain, pain during intercourse, heavy or irregular bleeding, bloating, and difficulty conceiving. Some women experience severe symptoms, while others may have minimal discomfort despite significant disease.

The exact cause of endometriosis is not fully understood, but hormonal factors, immune dysfunction, genetics, and retrograde menstruation may play a role. Diagnosis often involves a medical history, pelvic exam, and imaging such as ultrasound. In some cases, laparoscopy is needed to confirm the condition.

Although there is no definitive cure, treatment options are available to manage pain and support fertility. Early evaluation is important if symptoms persist or if you are trying to conceive without success.

What Is Low Ovarian Reserve?

Low ovarian reserve means the ovaries have fewer remaining eggs than expected for a woman’s age. It does not mean pregnancy is impossible, but it may reduce the chances of natural conception and shorten the reproductive window.

Women are born with a fixed number of eggs, and this number naturally declines over time. In some individuals, this decline occurs earlier or more rapidly than usual.

Ovarian reserve is commonly assessed using:

• Anti-Müllerian Hormone (AMH) levels

• Antral Follicle Count (AFC) on ultrasound

• Day 2–3 Follicle-Stimulating Hormone (FSH) levels

Lower AMH or AFC values may suggest diminished ovarian reserve. These tests estimate egg quantity, not egg quality, which is mainly influenced by age.

Some women have no symptoms. Others may experience difficulty conceiving or a reduced response to fertility treatments.

Early evaluation can help guide informed reproductive planning and timely medical support when needed.
