Aim: This study was conducted to determine the sexual dysfunction and postpartum-related factors in Bandar Abbas women in 2016.

Material and Methods: This analytical cross-sectional study used systematic random sampling on 432 postpartum women referred to Bandar Abbas Healthcare Centers. Data were collected by Demographic and Obstetrics Questionnaire and Female Sexual Function Index (FSFI) Questionnaire through interview and were analyzed by using SPSS ver.22 method.

Results: The overall rate of sexual dysfunction was reported 85.95%. The most common postpartum sexual dysfunction was pain sexual dysfunction during sexual intercourse. The mean score of all types of sexual dysfunction increased over time after delivery except sexual satisfaction so that the mean score of sexual satisfaction did not show significant differences over time. There was a significant relationship between sexual dysfunction with factors such as duration of marriage (p< 0.001), number of children (p<0.001), familial relationship (p=0.028), episiotomy status (P=0.002) and contraceptive method (p=0.001).

OBJECTIVE: To estimate the prevalence of postpartum dyspareunia.

SEARCH STRATEGY: Web of Science, Scopus, PubMed, and Embase databases were searched to July 2019 using keywords including 'perineal pain,' 'dyspareunia,' and 'sexual pain'.

SELECTION CRITERIA: Observational studies on the prevalence of postpartum dyspareunia were included.

DATA COLLECTION AND ANALYSIS: Two authors independently reviewed articles and extracted data. Study heterogeneity was evaluated by I2 index; publication bias by Egger and Begg tests.

MAIN RESULTS: Twenty-two studies enrolling 11 457 women were included. Based on meta-analysis, the overall estimated prevalence of dyspareunia was 35% (95% confidence interval [CI], 29%-41%). The prevalence was 42% (95% CI, 26%-60%) at 2 months, 43% (95% CI, 36%-50%) at 2-6 months, and 22% (95% CI, 15%-29%) at 6-12 months postpartum. Begg test showed no significant bias in data related to the prevalence of postpartum dyspareunia (p = 0.466).

METHODS AND ANALYSIS: All observational studies, including descriptive, descriptive-analytic, case-control, and cohort studies published between 1990 and 2019, will be included in the study. Review articles, case studies, case reports, letter to editors, pilot studies, and editorial will be excluded from the study. The search will be conducted in the Cochrane Central Register, MEDLINE, Google Scholar, EMBASE, ProQuest, Scopus, WOS, and CINAHL databases. Eligible studies should assess at least one of the sexual dysfunction symptoms in pregnant women or in the first year postpartum. Quality assessment of studies will be performed by two authors independently based on the NOS checklist. This checklist is designed to assess the quality of observational studies. Data will be analyzed using Stata software ver. 11. Considering that the index investigated in the present study will be the level of sexual disorder, standard error will be calculated for each study using binomial distribution. The heterogeneity level will be investigated using Cochran's Q statistic and I2 index in a chi-square test at a significance level of 1.1. Predictable limitations of this study included a small number and unacceptable quality of studies.

DISCUSSION: This systematic review addresses the factors associated with sexual dysfunction during pregnancy and postpartum. Considering the high prevalence of sexual dysfunction among women, the treatment of this problem has been highly sought after by the World Health Organization in recent years. The results of this study can help discover new strategies by introducing factors affecting women's sexual dysfunction, thereby eliminating or diminishing these factors, and play an important role in improving the quality of life of women during pregnancy and postpartum periods.
