Unexplained infertility affects many couples who receive normal fertility test results but still cannot achieve pregnancy naturally. In Hong Kong, fertility specialists typically develop personalized treatment plans based on age, reproductive history, ovarian function, and semen quality.
For suitable patients, intrauterine insemination (IUI) may be used as an initial treatment by improving sperm preparation and increasing the chance of fertilization. When IUI attempts are unsuccessful, IVF-ET provides a more advanced approach by allowing fertilization and embryo development to occur under controlled laboratory conditions.
Immune-related infertility, including the presence of anti-sperm antibodies, may interfere with sperm movement and fertilization. IUI and IVF-ET can help reduce the impact of these barriers through different reproductive strategies.
Modern assisted reproductive medicine provides couples with more options, transforming unexplained fertility challenges into manageable treatment pathways
