Short-Term Aerobic Exercise Did Not Change Telomere Length While It Reduced Testosterone Levels and Obesity Indexes in PCOS: A Randomized Controlled Clinical Trial Study.

Metabolic and hormonal outcomes of polycystic ovary syndrome (PCOS) have implications on telomere biology and physical activity may prevent telomere erosion. We sought to observe the effects of continuous (CAT) and intermittent (IAT) aerobic training on telomere length, inflammatory biomarkers, and its correlation with metabolic, hormonal, and anthropometric parameters of PCOS. This randomized controlled clinical trial study included 87 PCOS randomly stratified according to body mass index (BMI) in CAT ( = 28), IAT ( = 29) and non-training control group (CG, = 30).

Effects of continuous and intermittent aerobic physical training on hormonal and metabolic profile, and body composition in women with polycystic ovary syndrome: A randomized controlled trial.

Objective: To evaluate the effects of continuous (CA) and intermittent (IA) aerobic training on hormonal and metabolic parameters and body composition of women with polycystic ovary syndrome (PCOS).

Design: Prospective, interventional, randomized study.

Methods: Randomized controlled training (RCT) with sample allocation and stratification into three groups: CAT (n = 28) and IAT (n = 29) training and no training [control (CG), n = 30].

Association of measures of central fat accumulation indices with body fat distribution and metabolic, hormonal, and inflammatory parameters in women with polycystic ovary syndrome.

Objective: To investigate the associations among visceral adiposity index (VAI), lipid accumulation product (LAP), body fat percentage (%), and android/gynoid ratio (A/G ratio) in women with polycystic ovary syndrome (PCOS) and verify if the parameters representative of visceral obesity correlate with and exhibit the same frequency as body composition variables; anthropometric indices; and metabolic, hormonal, and inflammatory parameters.

Subjects And Methods: This was a cross-sectional study that included 94 women with PCOS. Hormonal, metabolic, and inflammatory parameters were analyzed in all women.

The relationship among sperm global DNA methylation, telomere length, and DNA fragmentation in varicocele: a cross-sectional study of 20 cases.

Varicocele pathophysiology is related to increased oxidative stress, which might result in loss sperm DNA integrity as well as in genomic instability. Sperm telomere shortening and loss of global DNA methylation are the main features of genomic instability, leading to cell senescence and death, whereas sperm DNA fragmentation (SDF) characterizes the loss of chromatin integrity. We hypothesize that sperm genomic stability and DNA integrity is reduced in infertile men with moderate and large-sized varicoceles, thus being candidate markers of sperm quality in varicocele-related infertility.

Inflammatory biomarkers and telomere length in women with polycystic ovary syndrome.

Objective: To analyze whether leukocyte telomere length (LTL) is impaired in women with polycystic ovary syndrome (PCOS).

Design: Case-control study.

Setting: Hospital.

[Frequency and risk factors for metabolic syndrome in adolescents and adults women with polycystic ovary syndrome].

Purpose: To compare the frequency of metabolic syndrome (MetS) and the risk factors associated with this syndrome in women from the Brazilian Southeast with polycystic ovary syndrome (POS) evaluated during adolescence and adult age.

Methods: This was a cross-sectional study conducted on 147 patients with a diagnosis of POS who were divided into two groups: Adolescents, 42 adolescents aged 13 to 19 years, and Adults, 105 women aged 20 to 40 years. The following factors were evaluated: clinical characteristics (body mass index - BMI, Ferriman index, abdominal circumference - AC, and systemic arterial pressure), mean ovarian volume, laboratory variables (serum androgen profile, lipid profile, glycemia, and fasting insulin), and frequency of MetS.
