Background
Inability to conceive after one year of sex without protection is considered as infertility that involves one out of five couples [1]. Infertility is a stressful condition that affects all aspects of affected couple’s life [2, 3]. Impaired mental, physical, social and personal aspects of life along with waste of time and money, marital disruption and divorce [1]. Almost 40% of couples who seek infertility treatment still cannot conceive [4]. Psychological problems such as depression, anxiety, stress, suicidal attempt are more common in infertile women [2, 3]. Literature show that sexual dysfunction is higher in infertile couples in comparison with healthy controls [5, 6]. Although sexual function is one of the key factors in physical and marital health, it is not considered as it should be. Different factors have been deliberated to influence sexual function in women with infertility such as age, psychological status, adverse effects of medications, and sex hormone status [1].
Recently some studies conducted to evaluate sexual function in these women and differentiate between sexual statuses of primary or secondary infertile cases but there is no study evaluating quality of sex in this group.

We designed this study to assess depression, sexual function and sexual quality of life in Iranian women with infertility.
Methods
This cross sectional study conducted in Women’s hospital (affiliated hospital of Tehran university of medical sciences) between March 2015 and March 2017.
Inclusion criteria were: Inclusion criteria were: age more than 18 and less than 40, candidates for IVF and no underlying diseases such as kidney disease, coronary disease, PCO (poly cystic ovarian syndrome). All cases were asked to fill informed consent forms before study.
Healthy subjects (from hospital workers) with above inclusion criteria and no history of infertility enrolled in the study.

They also were asked to fill valid and reliable Persian versions of BDI (Beck depression inventory), FSFIS (Female Sexual Function Index) and sexual quality of life-Female (SQOL-F) questionnaires.
BDI consists of 21 questions; each has scores between 0 and 3. Scores between 0 and 9 is indicative of not-depressed individuals, scores between 10 and 18 is indicative of mild, 19–29 moderate and > 29 severe depression [7].
FSFI includes 19 questions, evaluating sexual function in six domains (desire, arousal, lubrication, orgasm, satisfaction and pain. Total score shows sexual function [8]. Lower score is indicative of more sexual dysfunction. The cutoff point of 26.55 is considered to determine sexual dysfunction.
SQOL-F is a self-report questionnaire assessing the impact of sexual dysfunction. It measures sexual confidence, emotional well-being, and relationship issues. It includes 18 questions, each containing a six-point likert scale answers (completely agree to completely disagree). The total score is sum of total scores of questions. Higher the score, higher the quality of life [9].
SPSS version 24 (SPSS Inc., Chicago, IL, USA) was used for data analysis. Data was shown in mean ± SD. Independent sample t test and paired sample t test applied for continuous, as well as the Pearson X2 test with Fisher’s exact test used for assessment of categorical variables. Correlation coefficient was applied. Linera regression analysis conducted.
P-value < 0.05 was considered statistically significant.
Results
Two hundred and sixty four individuals participated in the study (115 healthy controls, 78 with primary and 71 with secondary infertility). Partner age, duration of marriage and history of abortion were significantly different between groups (Table 1).

Healthy subjects | 51(44.3%) | 64(55.7%) | 0.01 |
Primary infertility | 51(65.4%) | 27(34.6%) | |
Secondary infertility | 37(52.1%) | 34(37.9%) | |
BDI | 18 ± 9.5 | 11.3 ± 8.1 | < 0.001 |
SQOL-F | 73.4 ± 16.5 | 94.1 ± 12.8 | < 0.001 |
There was significant positive correlation between SQOL-F and total FSFI score (r = 0.59, p < 0.001) and also significant negative correlation between SQOL-F and BDI (r = − 0.49, p < 0.001).
Linear regression analysis by considering SQOL-F as dependent and age, BDI, duration of marriage, sexual dysfunction (FSFI ≤26.55 or > 26.55) showed that BDI and sexual dysfunction were independent predictors of SQOL-F (Table 4).

Discussion
To our knowledge this is the first study evaluating sexual quality of life in infertile women in Iran.
Anzeige
The results showed that sexual dysfunction is more common in women with primary infertility and BDI score was significantly higher in individuals with sexual dysfunction. The results also showed that total FSFI score and its domains are not significantly different between infertile subjects and healthy ones. These findings are compatible with Monga et al. findings. They compared 18 infertile couples and 12 healthy ones and reported no significant difference between sexual function of fertile vs infertile groups [4]. In our previous study, we only assessed sexual function in infertile women with primary or secondary infertility in comparison with controls. Our results showed that total FSFI score and all of its domains were significantly higher in controls vs. infertile ones while only desire subscale was significantly higher in primary group [1].
By comparing secondary and primary infertility groups of women, Keshin et al. stated that orgasm, satisfaction domain of FSFI and total FSFI scores were significantly lower in secondary groups and sexual dysfunction in secondary group after adjustment for confounders was 9.5 fold of primary group [10].
In current study, sexual dysfunction was significantly higher among women with primary infertility in comparison with secondary group and healthy ones.
In a previous study, Millheiser et al. found sexual dysfunction in 25% of fertile group and 40% of infertile women and against our findings, desire, arousal and satisfaction domains were significantly higher in fertile group [5].

Studies conducted on infertile women, mostly focused on general quality of life and did not considered sexual quality of life. In a recent study by Aduloju et al.,
Quality of life score of fertile women was significantly higher than infertile individuals and women with secondary infertility had overall higher scores [11].
In another study in Turkey, SEZGIN et al. reported worse quality of life in infertile women than fertile ones [12].
By means of FSFI and core Fertility Quality of Life questionnaires, Lo and Kok found that infertile women with sexual dysfunction had lower quality of life score [13].
Our results show that SQOL-F score was significantly lower in cases with sexual dysfunction and there was significant positive correlation between FSFI and SQOL-F scores.
Linear regression analysis also showed that BDI was a negative independent of SQOL-F while was a positive independent predictor.
Although most of the time it is neglected, sexual health affects general health and sexual problems negatively influence quality of life [14].
Literature shows that sexual dysfunction in patients with various diseases will result in impaired quality of life [15‐17].
SQOL includes questions assessing thoughts and feelings about sexual life containing sexual participation concern and sexual function perception [9].
Sexual confidence, emotional well-being, and relationship issues are evaluated by means of SQOL [18]. As it is presented, total FSFI and SQOL scores are moderately correlated which could be indicative of assessing related concepts which is compatible with Pakpour et al. findings [9].
It should be considered that infertility affects different aspects of couple’s lives including psychological well-being. Between 40 and 50% of infertile women experience emotional problems [19]. Depression, anxiety, marital dis-adjustment, sexual dysfunction and impaired quality of life reported in more women with infertility [1, 4]. The most prevalent psychological problem in infertile women is depression which is more common in cases with primary infertility [10]. Our results show that mean BDI score was significantly lower in healthy subjects than infertile ones.
This study has some advantages. First, it is the first study evaluating sexual quality of life in Iranian women with infertility. Second, we included either individuals with primary or secondary infertility as well as healthy controls.
This study had also limitations. First, it conducted in a tertiary center. Second, no comprehensive information of partners were available. Multi centric studies with large sample sizes are recommended.
Conclusion
Sexual function and quality of life related to sexual life should be considered in Iranian infertile ones. Depression as a crucial factor should be focused more in infertile women.
