Clinical outcomes and development of children born after intracytoplasmic sperm injection (ICSI) using extracted testicular sperm or ejaculated extreme severe oligo-astheno-teratozoospermia sperm: a comparative study.

To evaluate the clinical outcomes and development of children born after intracytoplasmic sperm injection (ICSI) with extracted testicular sperm or ejaculated extreme severe oligo-astheno-teratozoospermia (OAT) sperm. Retrospective study. Infertility clinic at Chang Gung Memorial Hospital. A total of 126 ICSI cycles were performed using extracted testicular sperm from men with azoospermia and 65 ICSI cycles using fresh ejaculated sperm from men with extreme severe OAT. Retrospective analysis of clinical outcomes and development of children born after ICSI with extracted testicular sperm or ejaculated extreme severe OAT sperm. Fertilization rates, number of grade 1 zygotes and number of embryos produced, implantation rate, clinical pregnancy rate, abortion and live birth rate per transfer, perinatal outcomes, and birth defects. The demographic and clinical factors, including age, E(2) level on hCG day, number of oocytes retrieved, normal fertilization rate, zygote grade 1 score distribution, number of top-quality embryos transferred, clinical pregnancy rate per transfer, chemical pregnancy rate per transfer, implantation rate, live birth rate per transfer, and abortion rate per transfer, were similar between the groups. Sixty live births resulted from 48 extracted testicular sperm cycles and 21 live births from 19 extreme severe OAT. The obstetric and perinatal outcomes were similar between the groups, and children conceived by using ICSI were healthy and without major psychomotor or intellectual development retardation. One case of tetralogy of Fallot occurred in each group. There is no evidence of differences in the clinical outcomes and development of children result after ICSI with extracted testicular sperm or ejaculated extreme severe OAT sperm.

Clinical outcomes and development of children born to couples with obstructive and nonobstructive azoospermia undergoing testicular sperm extraction-intracytoplasmic sperm injection: A comparative study.

To evaluate and compare the clinical outcomes and development of children born between obstructive azoospermia (OA) couples and nonobstructive azoospermia couples (NOA) after testicular sperm extraction (TESE) and intracytoplasmic sperm injection (ICSI). Data were collected from infertile couples suffering from azoospermia who underwent TESE and ICSI from January 2001 to December 2009 at Chang Gung Memorial Hospital, Taiwan. A total of 154 ICSI cycles were performed using extracted testicular sperm from men with obstructive azoospermia (67 ICSI cycles) and men with nonobstructive azoospermia (87 ICSI cycles). Retrospective analysis of clinical outcomes and development of children born after TESE-ICSE between obstructive azoospermia couples and nonobstructive azoospermia couples. The assisted reproductive technology (ART) result between OA and NOA groups, including age, E2 level on hCG day, number of oocytes retrieved, normal fertilization rate, zygote Grade 1 score distribution, number of top-quality embryos transferred, clinical pregnancy rate per transfer, chemical pregnancy rate per transfer, implantation rate, live birth rate per transfer, and abortion rate per transfer, were all similar. Thirty-one live births resulted from 67 ICSE cycles in the OA group and 33 live births from 87 ICSE cycles in the NOA group. The obstetric and perinatal outcomes were similar between the groups, and children conceived by using ICSI were generally healthy without raised tendency of major birth defect and development impairment. In our study, there were no differences in the fertility rate and clinic pregnancy rate between the OA and NOA groups using TESE-ICSI. Also, the clinical outcomes and development of children were similar between the OA and the NOA groups using TESE-ICSI.

Surgically retrieved spermatozoa versus ejaculated spermatozoa in modified natural IVF-ICSI cycles.

A retrospective cohort study was performed to evaluate the outcome of modified natural IVF-intracytoplasmic sperm injection (mnIVF-ICSI) cycles to compare 81 mnIVF-ICSI first cycles using ejaculated spermatozoa with 44 mnIVF-ICSI first cycles using surgically retrieved spermatozoa. There were no differences between the two groups in terms of number of oocytes retrieved, oocyte maturity or female age. However, male age was significantly higher in the surgically retrieved compared with the ejaculated group (41.5 versus 36.5 years, P=0.001). There were no significant differences in fertilization rate or cleavage rate between the ejaculated and the surgically retrieved groups; however the prevalence of embryo transfer was higher in the surgically retrieved group (65.9% versus 45.7%, P=0.03). Only single-embryo transfer was performed. Biochemical (34.5% versus 37.8%) and clinical (31.0% versus 35.1%) pregnancy rates per embryo transfer were similar between the ejaculated and the surgically retrieved groups. The data suggest that mnIVF-ICSI is an alternative treatment option in couples with severe male factor infertility where surgical sperm retrieval is required. The aim of the present study was to evaluate and compare the outcomes of modified natural IVF-intracytoplasmic sperm injection (mnIVF-ICSI) with surgically retrieved spermatozoa (in male partners with obstructive azoospermia) and ejaculated spermatozoa (in couples with mild-to-moderate male factor). Eighty-one mnIVF-ICSI first cycles using ejaculated spermatozoa were compared with forty-four mnIVF-ICSI first cycles using surgically retrieved spermatozoa. There were no differences between the two groups in terms of number of oocytes retrieved, oocyte maturity or female age. However, male age was significantly higher in the surgically retrieved compared with the ejaculated group. There were no significant differences in fertilization rate, or cleavage rate between the two groups; however, there were more patients having embryo transfers in the surgically retrieved group. Only single-embryo transfer was performed. Biochemical and clinical pregnancy rates per embryo transfer were similar between both groups. The data suggest that mnIVF-ICSI is an alternative treatment option in couples with severe male factor infertility where surgical sperm retrieval is required.
