Some men do not produce sperm at all or only in insufficient numbers and poor quality.
Many of these men can have their sperm aspirated directly from their testicles (TESA) or from the epididymis that
stores the sperm prior to an ejaculation (PESA, MESA).
The retrieved sperm are then used during
in vitro fertilization, gestational surrogacy or egg donation treatments with Intracytoplasmic Sperm Injection (ICSI).
The aspiration is a brief outpatient procedure requiring only mild sedation. Most sperm aspiration procedures are performed at our center.
