生殖地圖How Does Male Infertility Affect IVF Treatment? What Is ICSI?
Male factors (sperm issues) account for approximately 40–50% of infertility causes among couples. Common diagnostic tool is semen analysis (WHO 2021 reference values: progressive motility PR ≥ 32%, normal morphology ≥ 4%). When sperm problems are identified, ICSI (intracytoplasmic sperm injection) is a commonly used laboratory option in IVF treatment. The following is a neutral educational summary, not medical advice.
FAQ
How is male infertility diagnosed?
Common diagnostic tools include semen analysis (evaluating sperm concentration, motility, morphology), hormone tests, and, if necessary, testicular sperm extraction evaluation. Diagnosis must be made by a urologist or reproductive medicine specialist based on individual circumstances. This page provides neutral educational information, not medical advice.
What is ICSI (intracytoplasmic sperm injection)?
ICSI (Intracytoplasmic Sperm Injection) is a fertilization method in IVF where an embryologist injects a single sperm directly into an egg. It is used for cases of low sperm concentration, poor motility, or abnormal morphology. Whether to use it is determined by the physician.
What indicators are examined in a semen analysis report?
The World Health Organization (WHO) 2021 reference values include: semen volume ≥ 1.5 mL, total sperm count ≥ 39 million per ejaculate, progressive motility (PR) ≥ 32%, normal morphology ≥ 4%. Standards may vary slightly between laboratories; it is recommended to have your physician explain the significance of your individual report.
What are common causes of male factor infertility?
Common factors include varicocele, hormonal imbalances (e.g., low testosterone), vas deferens obstruction, chromosomal abnormalities (e.g., Y chromosome microdeletion, Klinefelter syndrome), and history of certain chemotherapy or surgeries. The exact cause requires diagnosis by a physician.
What tests are needed before a male enters an IVF cycle?
Typically, semen analysis, infectious disease screening (HIV, syphilis, hepatitis B/C), and if necessary, hormone evaluation and genetic counseling are required. In specific cases (e.g., azoospermia), testicular or epididymal sperm extraction evaluation (TESE/PESA/MESA) may be needed. Specific items depend on institutional protocols.
Can patients with azoospermia undergo IVF?
Azoospermia is classified as obstructive or non-obstructive. Obstructive cases (e.g., vas deferens blockage) can obtain sperm via epididymal or testicular extraction (PESA/TESE) for ICSI; non-obstructive cases are more complex, and the ability to retrieve sperm requires physician evaluation. This page provides neutral information, not medical advice.
What is the relationship between varicocele surgery and IVF treatment?
Varicocele surgery may improve semen parameters, but outcomes vary by individual and require several months of observation. Whether to undergo surgery and its impact on IVF planning should be evaluated jointly by a urologist and reproductive medicine specialist. This page provides neutral information.
Does using ICSI increase the cost of IVF?
ICSI typically involves an additional laboratory fee, which varies by institution. Testicular sperm extraction surgeries (TESE/PESA) are also billed separately. It is recommended to request a complete cost breakdown including possible procedures during consultation. This page provides neutral information; fees are subject to the institution's written explanation.
