Abstract

STUDY QUESTION:

Does fertility-related quality of life (FertiQOL) differ by infertility diagnosis between women with polycystic ovary syndrome (PCOS) and their partners, compared with couples with unexplained infertility (UI)?

SUMMARY ANSWER:

Women with PCOS report lower QOL than those with UI, whereas males with UI report lower QOL than males with PCOS partners.

WHAT IS KNOWN ALREADY:

The fertility-specific QOL survey, FertiQOL, has been used to examine fertility-related QOL in a number of worldwide cohorts. Few data have addressed fertility-related QOL as a function of infertility diagnosis. Overall, men report better QOL than women with infertility, and there is variation in FertiQOL scores across different samples from different countries.

STUDY DESIGN, SIZE, DURATION:

This was a prospective, cohort study derived from two concurrent, randomized clinical trials, and designed to examine QOL in infertile females with PCOS and UI at the time of enrollment compared with each other and their male partners; to compare concordance FertiQOL scores in this study across other worldwide cohorts; and to determine if baseline FertiQOL was associated with pregnancy outcome.

PARTICIPANTS/MATERIALS, SETTING, METHODS:

Women with PCOS and their partners (n = 733 and n = 641, respectively), and couples with UI (n = 865 women and 849 men) completed a validated fertility-specific QOL survey (FertiQOL) at the time of the study screening visit. PCOS women were randomized to either clomiphene citrate or letrozole treatment; couples with UI were randomized to clomiphene citrate, letrozole or gonadotrophin plus IUI. FertiQOL results were compiled by diagnosis (PCOS or UI) and compared by diagnosis and sex using Wilcoxon Rank-Sum testing. Relationships between baseline FertiQOL and pregnancy outcomes were examined using logistic regression. Multivariable models were performed to assess the association between FertiQOL scores and key participant characteristics.

MAIN RESULTS AND THE ROLE OF CHANCE:

Women with PCOS had lower total FertiQOL scores (72.3 ± 14.8) than those with UI (77.1 ± 12.8; P < 0.001); this was true for each domain (except Relational). These differences were largely explained by variation in BMI, hirsutism, household income and age. Women had lower overall FertiQOL scores than their male partners. Males with PCOS partners had higher scores than males with UI (84.9 ± 10.2 versus 83.3 ± 10.8; P = 0.003). Scores were not consistently associated with conception or pregnancy outcome.

LIMITATIONS, REASONS FOR CAUTION:

The use of multiple tests of association may have resulted in spurious statistically significant findings. Inherent sociodemographic differences between women with PCOS and those with UI largely account for the lower QOL in women with PCOS. Our study was unable to assess if changes in QOL affected pregnancy outcome as FertiQOL data were collected prior to treatment. Finally, the participants for both studies represent their local communities, but are not a population-based sample and thus firm conclusions about how representative these couples are to the general population must be made with caution.

WIDER IMPLICATIONS OF THE FINDINGS:

Women with PCOS with elevated BMI and hirsutism scores and with lower socioeconomic status may require more, targeted psychosocial support than those with other diagnoses. Possible attribution of infertility to the male partner appears to result in a lower QOL. There appears to be substantial national variation in FertiQOL scores, with US-based cohorts reporting overall higher QOL.
