Comparison of the Clinical Outcomes of Intracytoplasmic Sperm Injection Between Spermatozoa Retrieved From Testicular Biopsy and From Ejaculate in Cryptozoospermia Patients

Association of sperm source with miscarriage and take‐home baby after ICSI in cryptozoospermia: a meta‐analysis of testicular and ejaculated sperm

“…Four cohort studies were included in the qualitative and quantitative synthesis (Bendikson et al, 2008;Hauser et al, 2011;Ben-Ami et al, 2013;Cui et al, 2016).The process of study selection was shown in Fig. The citations from Cochrane database (including CENTRAL), Embase, Ovid Medline, PubMed, ScienceDirect, Scopus and Web of Science were 5, 54, 80, 25, 53, 77 and 36, respectively.…”

“…This study included four cohort studies that included 331 patients with 479 ICSI cycles (Bendikson et al, 2008;Hauser et al, 2011;Ben-Ami et al, 2013;Cui et al, 2016). The characteristics of included studies listed in Table 1 consisted of study country, study period, sample size, paternal and maternal age, ovulation method, period of ovulation trigger to oocyte aspiration, assessment of oocyte maturity, as well as risk of bias.…”

“…The characteristics of included studies listed in Table 1 consisted of study country, study period, sample size, paternal and maternal age, ovulation method, period of ovulation trigger to oocyte aspiration, assessment of oocyte maturity, as well as risk of bias. These studies converted about 17 years that were from 1996 to 2013 in China (Cui et al, 2016), Israel (Hauser et al, 2011;Ben-Ami et al, 2013) and USA (Bendikson et al, 2008). Mean paternal ages in each study were from 34.25 to 36.83; and mean maternal ages in each study were between 28.44 and 33.59.…”

“…Two studies recruiting 302 patients with 338 ICSI cycles reported miscarriage (Ben-Ami et al, 2013;Cui et al, 2016). Two studies recruiting 302 patients with 338 ICSI cycles reported miscarriage (Ben-Ami et al, 2013;Cui et al, 2016).…”

“…The systematic review conducted meta-analysis from 272 ICSI cycles with 2547 transplanted embryos and concluded no differences in the pregnancy rate and fertilization rate between the two sperm sources. In our previous work, we successfully identified six cohort studies on this topic and performed meta-analysis from 578 male infertility patients with 761 ICSI cycles (Bendikson et al, 2008;Hauser et al, 2011;Amirjannati et al, 2012;Ben-Ami et al, 2013;Cui et al, 2016;Ketabchi, 2016;Kang et al, 2018).
