IVF in the U.S., Mexico, and Japan Pre-Treatment Testing Guide: A Detailed Overview of Examinations for Both Men and Women

Before preparing for IVF in the United States, thorough and accurate testing is essential. It provides the foundation for ensuring that the entire process proceeds smoothly. Whether male or female, the following tests are indispensable and cover international standards and necessary medical requirements.

Male Testing Items

Male Testing: Understanding Sperm Quality and Reproductive Health

Male testing mainly focuses on semen quality and reproductive system health.

Semen Analysis: It is generally recommended to abstain from ejaculation for 2–7 days before the test, following the specific requirements of the laboratory. The test includes sperm concentration, total count, motility, and morphology, among other factors, and serves as an important basis for evaluating male fertility. If the results are abnormal, the doctor may recommend a repeat test to further assess semen quality.

When necessary, the doctor may also arrange related semen biochemical tests or other male reproductive health assessments based on the patient's medical history to understand the condition of the reproductive system and provide a reference for choosing the subsequent fertilization method.

Female Testing: Evaluating Ovarian Reserve and Uterine Environment

Female testing involves more items, mainly covering ovarian function, hormone levels, uterine condition, and pre-pregnancy health assessment.

AMH Test: Anti-Müllerian hormone helps evaluate ovarian reserve. It is generally not significantly affected by the menstrual cycle and can be used to help determine the ovarian stimulation protocol and predict ovarian response.

Sex Hormone Testing: Common tests include FSH, LH, estradiol, progesterone, prolactin, and testosterone. These tests are usually scheduled according to the menstrual cycle. Baseline hormone testing on days 2–3 of menstruation helps assess ovarian endocrine function.

Antral Follicle Count: Transvaginal ultrasound is used to observe the number of antral follicles and assess ovarian condition. It is usually performed early in the menstrual cycle, and the results can be analyzed together with AMH and hormone test results.

Uterine Assessment: Ultrasound examinations are used to evaluate uterine shape, endometrial thickness, and the uterine cavity. Further assessment of the uterine cavity may be performed when necessary to prepare for embryo transfer.

Thyroid Function Testing: Indicators such as thyroid-stimulating hormone help assess thyroid function and provide a reference for pre-pregnancy preparation and health management during pregnancy.

Cervical Screening: Cervical health is assessed through methods such as cervical cytology testing. The specific testing schedule can be determined based on previous screening records.

Complete Blood Count, Blood Type, and Red Blood Cell Antibody Screening: These tests are used to understand basic blood status, blood type, and relevant antibody information, providing a basis for treatment and pregnancy management.

In addition, the doctor may also arrange tests for rubella and varicella immunity, as well as vitamin D levels, to help assess pre-pregnancy health.

Tests Required for Both Men and Women

Before IVF treatment in the United States, both partners are generally required to complete relevant infectious disease screening, including tests for HIV, hepatitis B, hepatitis C, and syphilis. Depending on individual circumstances and clinic requirements, tests for chlamydia and gonorrhea may also be arranged. These tests help assess the health status of both partners and prepare for egg retrieval, sperm collection, embryo culture, and subsequent pregnancy management.

From the initial fertility assessment to ovarian stimulation, embryo culture, and transfer, every step needs to be arranged according to individual circumstances. The IVF USA team, founded by Dr. Nathan Zhang, has provided overseas assisted reproductive consultation services for more than ten years, offering services such as egg freezing in the United States, IVF in the United States, and surrogacy for those who need it. With nearly 20 years of experience in overseas assisted reproduction, IVF USA recognized the diverse and individualized nature of reproductive needs early on and established a presence in the Mexican market, becoming the Chinese representative of Power Fertility Center (POWER IVF) in Mexico. Dr. Nathan Zhang's services have now 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 regions such as Taiwan and Hong Kong. For families comparing medical options in different countries and planning their pre-pregnancy timelines and budgets, Dr. Nathan Zhang and his team can help organize testing arrangements and subsequent treatment plans based on their specific needs, giving every fertility plan a clearer starting point.
