Live birth rate with repeat microdissection TESE and intracytoplasmic sperm injection after a conventional testicular biopsy in men with nonobstructive azoospermia.

Objective: To determine live birth rate via m-TESE and ICSI in men who had a previous conventional testicular biopsy.

Study Design: Retrospective study was conducted to analyze 86 m-TESE procedures for ICSI in NOA patients who had a previous conventional TESE. Only motile spermatozoa were used for ICSI and all other forms were discarded.

Outcome of intracytoplasmic sperm injection cycles with fresh testicular spermatozoa obtained on the day of or the day before oocyte collection and with cryopreserved testicular sperm in patients with azoospermia.

Objective: To compare the outcome of intracytoplasmic sperm injection (ICSI)-ET cycles with fresh testicular spermatozoa obtained on the same day or the day before oocyte retrieval with frozen-thawed spermatozoa.

Design: Retrospective cohort study.

Setting: Fertility center.
