About half of the couples stopped before any fertility treatment was started and one-third stopped after at least one IVF cycle. The main reasons for withdrawal were emotional distress and poor prognosis. This insight may help to improve quality of patient care by making care more responsive to the needs and expectations of subfertile couples.
Overall success rate in couples with unexplained infertility is high. Most pregnancies are conceived spontaneously. We recommend that if the pregnancy prognosis is good, expectant management should be suggested. The prognosis criteria for treatment with IUI or IVF needs to be investigated in randomized controlled trials.
The results of this study align with the current literature, highlighting that incident reporting systems which do not embrace a more systematic methodology are making a poorer impact. We recommend that the HFEA strive to fully embed human factors methodologies into their incident reporting systems. We propose that human factors will enhance the reports and improve education, learning and corrective actions in fertility clinics.
In this longitudinal multicentre cohort study, the overall ongoing pregnancy rate after current evidence-based management in male subfertility was studied. All subfertile couples who visited the fertility clinic for the first time between 2002 and 2006, and had male subfertility as a single diagnosis (n = 762 of 2476 couples), were included in this study. Couples were grouped by the severity of male factor. Group I (n = 541) had a total motile sperm count (TMSC) 1-20 × 10(6). Group II (n = 161) had a TMSC <1 × 10(6). Group III (n = 60) had azoospermia. The overall ongoing pregnancy rate was 65.5% (500/762). The overall ongoing pregnancy rates in group I (69.3%) and group II (61.5%) were comparable (p = 0.06). However, group I and group II conceived significantly more frequently than group III (43.3%) (group I vs. group III p < 0.001 and group II vs. group III p = 0.02, respectively). Moreover, the spontaneous ongoing pregnancy rate in group I was 35.3%, in group II 22.4% and in group III, 1.7% (group I vs. group II p = 0.002; group I vs. group III p < 0.001; group II vs. group III p < 0.001). Thus, despite a significant difference in spontaneous ongoing pregnancy rates, except for azoospermia, the overall ongoing pregnancy rates, regardless of the severity of the male factor, were comparable. Couples with poorer sperm parameters, however, have to undergo more invasive treatment to reach the same goal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
