Introduction: Menopause is characterized by the depletion of ovarian follicles and the gradual decline in estradiol levels, which ends with the definitive cessation of menstrual periods (menopause). As a result of hypoestrogenism, characteristic symptoms, such as hot flashes, night sweats, vaginal dryness, dyspareunia, insomnia, mood swings and depression can be observed. There is also the weakening of the pelvic floor muscles (MAP) as a result of progressive muscle-aponeurotic and connective atrophy with consequent decreased sexual function. Objective: To evaluate the strength of MAP, sexual function and quality of life of menopausal women. Methodology: This is an observational, analytical, cross-sectional design. The sample consisted of 55 women (35 postmenopausal and 20 perimenopausal), aged between 40 and 65, who were assessed by muscle strength and perineometry test. For the assessment of sexual function and quality of life, used the Female Sexual Function Index (FSFI) and Utian Quality of Life (UQOL), respectively. Statistical analysis was performed using Pearson's correlation and multivariate analysis. Results: The mean age was 52.78 (± 6.47 years). Sexual dysfunction presented, 61.8% of participants (43.62% of postmenopausal and perimenopausal 18.17%). Muscle strength test and the maximum perineometry had a median of 3.00 (Q25: 2 e Q75: 4) and 33,50 cmH20 (Q25: 33,5 e Q75: 46,6), respectively. No correlation was found between sexual function and muscle strength (r = 0.035; p = 0.802) and between sexual function and perineometry (r = 0.126; p = 0.358). The mean total score of UQOL was 74.45 (± 12.23). Weak positive correlation was found between sexual function and quality of life (r = +0.422 p = 0.001). Multivariate analysis identified associations between sexual function and variables: quality of life, climacteric symptoms, physical activity and education level. Conclusions: These results suggest that the climacteric symptoms, quality of life, physical activity and level of education are associated with sexual function in menopausal women. However, the muscular component of sexual function needs to be further investigated in this context.

This study evaluated the effect of indole-3-acetic acid (IAA) in the activation of goats preantral follicles (FOPA). Were used four pairs of ovaries of adult mixed breed goats. Each ovarian pair was divided into 23 fragments. One fragment was fixed for histology and other fragment was using to follicular isolation procedure. The remaining fragments were cultured in 1.0 ml of Minimum Essential Medium (MEM) or MEM supplemented with IAA at concentrations of 10, 40, 100, 500 or 1000 ng/mL. The in vitro culture was performed at 39°C in incubator with 5% CO2 for 1, 3 and 5 days. After in vitro culture was evaluated histological integrity and viability of FOPA. The addition of 100 ng/ml of IAA to MEM showed a significant increase in follicles transition in the third day of in vitro culture, characterizing follicular activation. Moreover, this concentration was obtained maintaining the histological integrity of PAF by the fifth day of in vitro culture. The viability test confirmed the results of histology. Thus, we conclude that IAA can promote the activation of goats FOPA
