Despite the increasing use of medically assisted reproduction (MAR) in modern societies, there is limited evidence on whether conceiving with MAR or remaining involuntarily childless after MAR is associated with partnership stability. While older age, the more advantaged socioeconomic position of women undergoing MAR and their strong fertility intentions could lead to higher partnership stability, the experience of infertility and undergoing MAR may have an opposite effect, especially if couples remain involuntarily childless. Using data on Finnish nulliparous couples from 1995–2017 (N = 149,884) and event‐history models, we compare the risk of separation of couples who remained childless after MAR (N = 3871), who conceived through MAR (N = 14,474), who conceived naturally without MAR (N = 167,962) or with a prior history of MAR (N = 2273). Couples who remained childless after MAR had a higher risk of separation than couples who conceived with MAR or naturally. The higher risk of separation decreased over time since the discontinuation of treatments but persisted over the longer term. There were no differences in the risk of separation between couples who conceived with MAR or naturally. The results suggest that involuntary childlessness after MAR is associated with an increased risk of separation while undergoing MAR/experiencing infertility does not seem to play a role.

医疗辅助生殖和伴侣关系稳定性


尽管现代社会越来越多地使用医疗辅助生殖 (MAR)，但关于 MAR 受孕或 MAR 后非自愿无子女是否与伴侣关系稳定性相关的证据有限。虽然接受 MAR 的女性年龄较大、社会经济地位更有利以及她们强烈的生育意愿可能会导致更高的伴侣关系稳定性，但不孕经历和接受 MAR 可能会产生相反的效果，特别是如果夫妇非自愿地没有孩子。使用 1995 年至 2017 年芬兰未生育夫妇 (N = 149,884) 的数据和事件历史模型，我们比较了 MAR 后仍无子女的夫妇 (N = 3871) 和通过 MAR 怀孕的夫妇 (N = 14,474) 的分居风险，没有 MAR 的自然受孕者 (N = 167,962) 或有 MAR 病史的人 (N = 2273)。 MAR 后仍然没有孩子的夫妇比 MAR 或自然受孕的夫妇分居的风险更高。自停止治疗以来，较高的分离风险随着时间的推移而降低，但长期持续存在。通过 MAR 受孕或自然受孕的夫妇之间的分居风险没有差异。结果表明，MAR 后非自愿无子女与分居风险增加有关，而经历 MAR/经历不孕似乎没有影响。
