Total and bioavailable 25-hydroxyvitamin D is not associated with improved sexual dysfunction following vitamin D supplementation in women with polycystic ovarian syndrome: a pilot study.

BACKGROUND: Vitamin D (Vit D) deficiency has been linked to symptoms of polycystic ovary syndrome (PCOS), yet little is known about Vit D supplementation as a treatment for sexual dysfunction (SDy) in women with PCOS. AIM: To explore the implications of serum total 25-hydroxyvitamin D (25[OH]D) and bioavailable 25[OH]D (bio-25[OH]D) status and replacement on women with PCOS and SDy. METHODS: Reproductive-age women with PCOS who were not desiring fertility were eligible provided that they also had SDy, as assessed by the Female Sexual Function Index (FSFI), and were without severe depression, as evaluated by the Beck Depression Inventory II (BDI-II). Participants were given the recommended dietary allowance of Vit D (600 IU daily) plus hormonal contraception (HC; cyclic ethinyl estradiol/drospirenone) or no HC for 6 months. Comparisons between groups were analyzed by chi-square test and t-test, and Pearson's correlation coefficient analyzed correlations between FSFI with demographics, BDI-II, androgen levels, and total and bio-25[OH]D. OUTCOMES: The outcomes included SDy (FSFI <26.55), total and serum bio-25[OH]D levels, and total and free testosterone. RESULTS: A total of 42 women without severe depression completed the FSFI, with 28 (66.7%) having SDy. All FSFI domains, including arousal, lubrication, orgasm, and pain, were significantly lower as compared with women without SDy, with no associations with respect to demographics, total and free testosterone, or total and bio-25[OH]D. Vit D replacement was initiated with HC (n = 18) or no HC (n = 10), and for those completing the study, FSFI improved (score >26.55) in 61% (11/18) regardless of the treatment group. A time-treatment effect showed a significant change for the domain of orgasm, suggesting that HC had more of an impact than Vit D replacement. Improvement in sexual function as a dichotomous variable was not associated with age, body mass index, other demographics, total and free testosterone, total and bio-25[OH]D, or HC use. CLINICAL IMPLICATIONS: Due to the prevalence of SDy in women with PCOS, efficacious treatment options are necessary. STRENGTHS AND LIMITATIONS: This study is the first to analyze the effect of Vit D supplementation on SDy in women with PCOS. Limitations included the small number of participants who completed the study, thus limiting meaningful conclusions and generalizability. CONCLUSION: Vit D status was not associated with SDy and BDI-II. While HC may have played a role, standard Vit D supplementation could not account for the noted improvement in FSFI in women with PCOS.

Fertility and Sterility top videos from 2021.

OBJECTIVE: To objectively grade all video publications in Fertility and Sterility during the year 2021 and compile a list of the top 10 surgical videos. DESIGN: A descriptive presentation of the 10 highest-scoring video publications from Fertility and Sterility in the year 2021. SETTING: Not applicable. PATIENT/ANIMALS: Not applicable. INTERVENTIONS: J.F., Z.K., J.P.P., and S.R.L. acted as independent reviewers of all video publications. A standardized scoring method was used to score all videos. MAIN OUTCOME MEASURES: Up to 5 points were awarded for each of the following categories: scientific merit or clinical relevance of the topic; clarity of the video; use of an innovative surgical technique; and video editing or the use of marking tools on the video to highlight important features or surgical landmarks. This allowed a maximum score of 20 for each video. The number of YouTube views and likes was used as a tiebreaker if ≥2 videos scored similarly. The interclass coefficient from a 2-way random effects model was calculated to assess the agreement among the 4 independent reviewers. RESULT(S): A total of 36 videos were published in Fertility and Sterility during the year 2021. After averaging scores from all 4 reviewers, a top-10 list was created. The overall interclass correlation coefficient for the 4 reviews was 0.89 (95% confidence interval, 0.89-0.94). CONCLUSION(S): An overall substantial agreement was noted among the 4 reviewers. A total of 10 videos reigned supreme from a list of very competitive publications that had already undergone the peer review process. The subject matter of these videos ranged from complex surgical procedures, including uterine transplantation, to common procedures, such as GYN ultrasound.

Influence of Lab Adapted Natural Diet and Microbiota on Life History and Metabolic Phenotype of Drosophila melanogaster.

Symbiotic microbiota can help its host to overcome nutritional challenges, which is consistent with a holobiont theory of evolution. Our project investigated the effects produced by the microbiota community, acquired from the environment and horizontal transfer, on metabolic traits related to obesity. The study applied a novel approach of raising Drosophila melanogaster, from ten wild-derived genetic lines on naturally fermented peaches, preserving genuine microbial conditions. Larvae raised on the natural and standard lab diets were significantly different in every tested phenotype. Frozen peach food provided nutritional conditions similar to the natural ones and preserved key microbial taxa necessary for survival and development. On the peach diet, the presence of parental microbiota increased the weight and development rate. Larvae raised on each tested diet formed microbial communities distinct from each other. The effect that individual microbial taxa produced on the host varied significantly with changing environmental and genetic conditions, occasionally to the degree of opposite correlations.
