Intracytoplasmic Sperm Injection

Appointment New Patient Appointment or 214-645-8300

Intracytoplasmic sperm injection (ICSI) is an in vitro fertilization procedure in which a single sperm is injected directly into an egg using an extremely thin glass needle.

The sperm can be collected from an ejaculation, the epididymis, or the testis.

The success rate of ICSI is close to that achieved with conventional in vitro fertilization procedures performed when men have normal sperm counts.
