CLINICAL OUTCOMES IN PATIENTS WITH CONGENITAL BILATERAL ABSENCE OF THE VAS DEFERENS (CBAVD) UNDERGOING TESTICULAR SPERM EXTRACTION-INTRACYTOPLASMIC SPERM INJECTION (TESE-ICSI)

Congenital bilateral absence of the vas deferens, cystic fibrosis mutation analysis and intracytoplasmic sperm injection.

The aim of this study was to assess the outcome of intracytoplasmic sperm injection (ICSI) with fresh and frozen-thawed surgically retrieved spermatozoa from men diagnosed with congenital bilateral absence of the vas deferens (CBAVD). Twenty-seven azoospermic men with their partners were treated [25 with CBAVD and two with clinical cystic fibrosis (CF)]. CF gene mutation analysis and genetic co...

Intracytoplasmic sperm injection (ICSI).

Intracytoplasmic sperm injection (ICSI)

IVF has become a well-established treatment for certain types of infertility, including long-standing infertility due to tubal disease, endometriosis, unexplained infertility or infertility involving a male factor. Soon it became clear that certain couples with severe male-factor infertility could not be helped by conventional IVF. Extremely low sperm counts, impaired motility and/or abnormal m...

Long‐term clinical outcomes of testicular sperm extraction and intracytoplasmic sperm injection for infertile men

Purpose To find the best methods to achieve the highest pregnancy and birth rates for couples needing testicular sperm extraction (TESE)-intracytoplasmic sperm injection (ICSI). Methods Retrospectively studied were 801 patients with male factor infertility who had undergone TESE-ICSI between April, 1996 and July, 2016 and who had been categorized into four groups: obstructive azoospermia (OA)...

Live birth rates after MESA or TESE in men with obstructive azoospermia: is there a difference?

STUDY QUESTION How do live birth rates compare after intracytoplasmic sperm injection (ICSI) for men with obstructive azoospermia when using sperm derived from testicular sperm extraction (TESE) versus microsurgical epididymal sperm aspiration (MESA)? SUMMARY ANSWER Our study suggests that proximal epididymal sperm (from MESA) result in higher live birth rates as compared with testicular sper...
