Medical and reproductive history
The clinician may ask about previous pregnancies, surgery, infections, medications, heat or toxin exposure, sexual health and lifestyle factors.
Semen analysis
A laboratory analysis assesses semen volume and sperm concentration, movement and form. Because results can vary, repeat testing may sometimes be recommended.
Further investigations
Hormone tests, ultrasound, genetic assessment or specialist examination may be considered when the history or semen findings indicate a reason.
Treatment planning
Depending on the cause, options may include treating an underlying condition, surgery, lifestyle guidance, IUI, IVF, ICSI or surgical sperm retrieval.
