Sexual functions and satisfaction are affected during pregnancy along with the physical and mental changes and social, cultural, religious and emotional effects experienced during pregnancy.
This study was conducted descriptively and prospectively in order to evaluate sexual function and satisfaction in all three trimesters of nulliparous pregnant women.

The study was conducted with 256 pregnant who applied in the Pregnancy Outpatient Clinic of a hospital in Istanbul. Pregnant Information Form, Female Sexual Function Index (FSFI) and Sexual Satisfaction Scale for Women (SSSW) were used for data collection. The data were collected with face-to-face interviews with pregnant in 1st, 2nd and 3rd trimesters for 3 times in total.

The average age of pregnant is 26,82±5,36, 62,9% of them are housewives and in 59,8% of them family income is equal to family expenses. It was determined that the sexual life of women during pregnancy was negatively affected. The FSFI scores in all
three trimesters were 20,36±10,19, 22,04±11,32 and 9,94±10,41, respectively. The SSSW scores were 56,30±8,51, 59,86±8,0 and 45,15±8,2, respectively. Although there was a slight increase in FSFI and SSS-W scores in the second trimester, it was determined
that there was a significant decrease in the third trimester. It was found that sexual dysfunction was experienced in all three trimesters during pregnancy. The total score cut-off point for FSFI was below 26,55 and the rate of sexual dysfunction was 60,28%,
64,74% and 90,88%, respectively, according to trimesters. In the correlation analysis performed between FSFI and SSS-W, a positive, high degree and significant relationship was found in all three trimesters.

As a result of the findings obtained;
• In the first evaluation of pregnant women, in addition to detailed physical examination, evaluation of sexual functions and providing care with a holistic approach,
• Increasing the quality of life by explaining the changes and problems that the pregnant woman will experience in terms of sexual functions and satisfaction according to the trimesters,
• Planning care and trainings considering the trimesters,
• Nurses should have sufficient knowledge and skills to evaluate sexual function,
• Planning sexual health training in line with a specific program in antenatal check-ups and, if possible, conducting trainings as a couple,
• Considering the cultural characteristics of the couples and developing an individual approach can be recommended.

As a result, it was observed that female sexual functions and sexual satisfaction were negatively affected in all three trimesters
of pregnancy, more prominently in the third trimester.
