Pelvic floor-related sexual functioning in the first 24 months postpartum: Findings of a large cross-sectional study.

Introduction: The pelvic floor is exposed to differing stresses and trauma depending on the mode of birth. At the same time, the pelvic floor plays a crucial role in female sexual functioning (FSF). Whereby FSF encompasses different dimensions, from subjective satisfaction to physiological aspects, such as lack of pain and orgasm ability. The aim of the study presented here is to assess FSF in relationship to postpartum pelvic floor disorder based on the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire, IUGA-Revised (PISQ-IR), in a large convenience sample and to identify whether there is an association between mode of birth as well as perineal injuries and FSF of women up to 24 months postpartum.

Material and methods: We conducted a cross-sectional online survey and recruited via social media women up to 24 months after birth of their last child. FSF was surveyed using the PISQ-IR. Details were also collected on all previous births and birth-related perineal trauma, as well as current breastfeeding, obesity, and socio-demographics. Multivariate models were then calculated to determine a possible association between FSF and birth mode.

Results: The data basis is the responses of 2106 survey participants within the first 24 months postpartum. Even 12-24 months postpartum, 21% of respondents are not sexually active, which burdens almost 44% of these women. With regard to mode of delivery, differences in FSF are only evident in individual dimensions of the PISQ-IR. The dimensions "Condition Impact" and "Condition Specific" were significantly associated with more impairments in sexually active respondents up to 12 months postpartum whose last mode of delivery was forceps or vacuum extraction. If a perineal tear had occurred during last birth, this was significantly associated with a lower PISQ-IR subscore in the "Condition Impact," "Condition-Specific," "Global Quality," "Partner-Related," and "Arousal" models. The low variance explanation shows that further relevant factors on female sexuality may exist.

Conclusions: The issue of impairments in FSF following childbirth, persisting for an extended period of time, is a significant postpartum concern. Due to the very different dimensions of FSF, the influence of the mode of delivery must be considered in a differentiated way.
