Trying to Conceive During Ovulation Without Success? A Guide to IVF and IVF-PGT in the U.S., Mexico, and Japan

Many couples carefully track their menstrual cycles, use ovulation test strips, and even schedule intercourse around their fertile days in the hope of conceiving as soon as possible. However, understanding ovulation patterns does not guarantee pregnancy every month. If pregnancy does not occur despite ongoing attempts, it is important to look beyond timing and consider whether factors such as age, ovarian function, and sperm quality may be affecting fertility.

How Do You Calculate Your Fertile Window? Timing Is Not Everything

A woman's fertile window generally includes the five days before ovulation and the day of ovulation itself. Sperm can survive in the female reproductive tract for several days, while an egg can usually be fertilized for approximately 12 to 24 hours after ovulation. Therefore, timing intercourse within the fertile window can improve the chances of natural conception.

For women with regular menstrual cycles, ovulation often occurs around the middle of the cycle. For example, a woman with a 28-day cycle may ovulate around day 14, while someone with a 35-day cycle may ovulate later. However, ovulation does not always occur on day 14, and both cycle length and ovulation timing can be affected by various factors. Menstrual tracking apps primarily predict ovulation based on previous cycles and cannot confirm exactly when ovulation occurs in each cycle. Ovulation test strips, changes in cervical mucus, and guidance from a healthcare professional can help identify the fertile window more accurately.

How Long Should You Try to Conceive Before Considering IVF?

Natural conception depends on several steps working together, including ovulation, fertilization, embryo development, and implantation. Even when intercourse is appropriately timed, factors involving the fallopian tubes, uterine environment, semen quality, and age may affect the chances of pregnancy.

In general, women under 35 with no known fertility problems may consider an infertility evaluation after 12 months of regular attempts without pregnancy. Women aged 35 and older are generally advised to seek evaluation after six months. Those over 40, or those with irregular periods, fallopian tube problems, or other known fertility concerns, should consider consulting a reproductive specialist sooner.

IVF is not limited to couples who have been trying to conceive for many years. For individuals with diminished ovarian reserve, tubal factor infertility, male factor infertility, or other conditions affecting conception, a doctor can discuss appropriate treatment options based on the evaluation results.

What Are the Features of IVF-PGT?

IVF-PGT generally refers to assisted reproduction combined with preimplantation genetic testing (PGT). After embryos have developed to an appropriate stage in the laboratory, genetic information can be analyzed according to the type of test performed. The results can then be considered alongside embryo development when planning a transfer.

PGT includes different types of testing. For example, PGT-A is primarily used to assess chromosome number abnormalities in embryos. For people pursuing pregnancy at an advanced maternal age, the risk of chromosomal abnormalities generally increases as a woman gets older.

Dr. Nathan Zhang points out that IVF treatment for women of advanced maternal age requires a comprehensive assessment of age, ovarian reserve, previous treatment history, and overall health. An individualized ovarian stimulation and egg retrieval plan is essential. Medication selection, dosage adjustments, retrieval timing, and embryology laboratory techniques can all influence the treatment process and its outcomes. Women over 40 should establish realistic expectations based on their individual assessments and explore feasible fertility options as early as possible.

The team founded by Dr. Nathan Zhang at IVF USA has provided overseas assisted reproduction consulting services for more than ten years, offering egg freezing in the United States, IVF in the United States, and third-party reproduction services to those in need. With nearly 20 years of experience in overseas assisted reproduction, IVF USA recognized the diverse and personalized nature of reproductive needs and established a presence in the Mexican market early on, becoming the Chinese representative of Power Fertility Center in Mexico, also known as POWER IVF. Dr. Nathan Zhang's services have since expanded beyond the United States to include IVF and egg freezing in Mexico, IVF and egg freezing in Japan and Thailand, as well as services in Taiwan and Hong Kong. For those trying to conceive, exploring IVF-PGT, or evaluating their next treatment steps, establishing a clear plan for testing and medical care can provide a stronger basis for choosing the approach that best suits their needs.
