Comprehensive semen analysis to assess fertility potential
A semen analysis is the single most important first step in understanding male fertility — yet it is often overlooked or delayed. In Thailand, you can access a full laboratory workup including advanced tests like DNA fragmentation within days, not weeks, and at a fraction of the cost you would pay at home.
Semen analysis evaluates sperm health by measuring count, motility, morphology, and volume — providing a clear picture of male reproductive potential. Results are interpreted against WHO reference values and are essential for guiding fertility treatment decisions.
Computer-assisted sperm analysis (CASA) technology delivers objective, operator-independent readings for maximum accuracy. Advanced testing such as DNA fragmentation analysis can reveal hidden causes of infertility or recurrent miscarriage that standard parameters alone may not detect, guiding the choice between IUI, IVF, and ICSI.
A semen analysis involves producing a sample by masturbation into a sterile container, typically at the clinic. The sample is then assessed in the laboratory using standardised methods. Your specialist may recommend additional advanced tests depending on your history and initial results.
There are two main levels of analysis:
The foundation of male fertility investigation. A fresh sample is assessed for volume, pH, sperm concentration, total sperm count, progressive motility, total motility, and morphology. Results are compared against WHO 2021 reference values. Computer-assisted sperm analysis (CASA) is used at leading Thai clinics for precise, operator-independent readings.
When standard analysis is normal but fertility problems persist, or when results are borderline, advanced tests can reveal hidden issues. DNA fragmentation testing assesses the integrity of genetic material inside sperm — a key factor in fertilisation, embryo development, and miscarriage risk. Reactive oxygen species (ROS) testing and anti-sperm antibody panels may also be recommended.
You'll be asked to abstain from ejaculation for 2–5 days before providing your sample. Avoid alcohol, saunas, and hot baths in the days leading up to the test. Your clinic will provide clear instructions when you book.
The sample is produced by masturbation in a private room at the clinic and handed directly to the laboratory. This ensures the sample is analysed fresh, within the optimal time window. If producing a sample at the clinic is difficult, speak with your coordinator about alternatives.
Standard results are usually available within 1–2 hours. DNA fragmentation and advanced tests may take 1–2 days. Each parameter is reviewed with you in detail so you understand the numbers, what they mean for your fertility, and what the recommended next steps are.
If results are abnormal, a repeat test in 6–8 weeks is usually recommended to confirm findings, alongside lifestyle modifications or further investigations. If results are normal, your fertility team can focus on other factors. A written report is provided for your records and for any treating physician at home.
Semen analysis is a non-invasive laboratory test with no physical risks. The main considerations are related to sample quality and interpretation.
Results are always interpreted in the context of your full medical history and your partner's assessment. If any parameter is abnormal, a repeat test and further investigation are recommended before drawing conclusions.
