Abstract

STUDY QUESTION
Which success rates do female and male IVF patients expect, what determines their expectations and do patients reconsider their expectations after receiving a personal IVF prognosis at the expense of anxious reactions?

SUMMARY ANSWER
Female and male IVF patients have unrealistic high expectations which are positively associated with their dispositional optimism, and which are only reconsidered by patients receiving a less than average IVF prognosis, which leads to more anxious reactions in females.

WHAT IS KNOWN ALREADY
Female patients undergoing IVF are known to have unrealistic expectations of the success of their own IVF cycle. The available evidence suggests women expect above average performance of their fertility clinic and (family) reproductive systems. The association of gender and personality trait dispositional optimism, with expectations of IVF success and the impact of providing couples with their IVF prognosis have not been studied previously.

STUDY DESIGN, SIZE, DURATION
A total of 148 partnered individuals participated in this prospective survey at two separate points in treatment: following oocyte aspiration (T1) and embryo transfer (T2) (2019–2020, participation rate = 85%). At the time of embryo transfer, gynaecologists provided couples with their IVF prognosis, calculated with the Adapted van Loendersloot model. Women and their male partners completed questionnaires independently and immediately following oocyte aspiration and embryo transfer.

PARTICIPANTS/MATERIALS, SETTING, METHODS
Dispositional optimism (‘LOT-R’ questionnaire) and expectations of IVF success (numerical rating scale) were assessed in eligible couples commencing a 2nd–6th IVF cycle on T1. Expectations of IVF success and anxiety (‘Spielberger State-Anxiety Inventory’) were (re)assessed on T2. The inter-partner correlation of expectations of IVF success was examined. Linear mixed models examined hypothesized determinants of expectations of IVF success (T1) and explored (determinants of) whether participants reconsidered their expectations after receiving their IVF prognosis (T1–T2) and whether couple’s IVF prognosis was associated with anxious reactions (T2).

MAIN RESULTS AND THE ROLE OF CHANCE
The mean of the IVF success rates expected by patients immediately after oocyte aspiration was 59.1% (±20.0), irrespective of gender (P = 0.077). Partners expectations of IVF success were moderately correlated (r = 0.483; P &lt; 0.001). Expectations of IVF success were positively associated with the participant’s dispositional optimism (P &lt; 0.001) but were not associated with their partner’s dispositional optimism, women’s age and their previous (un)successful IVF experiences. Gynaecologists gave couples their calculated IVF prognosis ranging from 4.8% to 69.2% (mean = 30.9%) at the time of embryo transfer. Gender did not influence whether participants reconsidered their expectations after receiving their prognosis. In contrast to the subgroup (n = 78), who received at least an average IVF prognosis and that did not reconsider their expectations of IVF success, the subgroup (n = 70) receiving a below average IVF prognosis lowered their expectations of IVF success (interaction effect: P &lt; 0.001) from 55% to 46%. A below average IVF prognosis was associated with anxious reactions in women but not in men (interaction effect: P = 0.011).

LIMITATIONS, REASONS FOR CAUTION
The study design and sample size were more optimal for examining hypothesized determinants of patient’s expectations of IVF success than for studying the impact of sharing prognoses with patients. Whether (reconsidering) expectations influences IVF discontinuation rates and achieved live birth rates has yet to be followed-up.

WIDER IMPLICATIONS OF THE FINDINGS
Clinics are advised to offer patients the opportunity of receiving their IVF prognosis. Providing prognoses is in line with patient preferences and tempers the unrealistic high expectations of both partners in couples with a less than average prognosis. A sensitive communication style is indicated, as lower prognoses are associated with mild anxious reactions in women.
