BACKGROUND
There is an increasing literature on women’s perception of subfecundity and contraceptive use, with studies showing that women with perceived difficulties conceiving are more likely to have an unintended pregnancy because of a lower reliance on contraception. There is little research investigating the correlates of perceived subfecundity, and quantitative investigation of couple-level perceived subfecundity appears absent from the literature, which is somewhat surprising, as the inability to have a child is a couple-level outcome. Furthermore, most studies that relate to perceived subfecundity and the use of contraception, or lack thereof, are typically limited to young adults.

OBJECTIVE
The aim of this study is to explore the couple-level correlates of perceived subfecundity and to investigate the relationship between perceived subfecundity and contraceptive use among a nationally representative sample of couples.

METHODS
Drawing on data from the Household Income and Labour Dynamics in Australia (HILDA) survey, binary and multinomial logistic regression models are estimated using the couple-dyad as the unit of analysis.

RESULTS
Both biological and life-course interference factors are strong predictors of perceived subfecundity at the couple level, with women’s characteristics more influential than their partner’s characteristics. Additionally, couples in which at least one partner perceives subfecundity are less likely to use contraception, regardless of their short-term intentions or desire to have a child.

研究感知生育能力不足和避孕使用的二元方法（Ester Lazzari、Edith Gray、Bernard Baffour）

背景
关于女性对生育能力不足和使用避孕药具的看法的文献越来越多，研究表明，由于对避孕药具的依赖程度较低，有受孕困难的女性更有可能意外怀孕。很少有研究调查感知生育能力低下的相关性，文献中似乎没有对夫妇水平感知生育能力低下的定量调查，这有点令人惊讶，因为无法生育是夫妻水平的结果。此外，大多数与感知到的生育能力低下和避孕措施的使用或缺乏相关的研究通常仅限于年轻人。

客观的
本研究的目的是探索感知生育能力低下的夫妻水平相关性，并调查全国代表性夫妻样本中感知生育能力低与避孕药具使用之间的关系。

方法
根据澳大利亚家庭收入和劳动力动态 (HILDA) 调查的数据，使用夫妻二元组作为分析单位估计二元和多项逻辑回归模型。

结果
生物和生命过程的干扰因素都是夫妻双方感知到的生育能力低下的有力预测因素，女性的特征比其伴侣的特征更有影响力。此外，至少有一个伴侣认为生育能力低下的夫妇不太可能使用避孕措施，无论他们的短期意图或想要孩子的愿望如何。
