Context: Polycystic ovary syndrome (PCOS) is common and diagnosis requires an elevated testosterone. The clinical importance of adrenal 11-oxyandrogens in PCOS is unclear.
Objective: We sought to determine if 11-oxyandrogens 1) better identify PCOS diagnosis compared to testosterone, 2) predict clinical comorbidities of PCOS, and 3) are altered with an combined oral contraceptive pill (COCP) or metformin therapy.
Methods: Data from 200 adolescent female participants aged 12 to 21 years, most with obesity, enrolled across 6 studies in pediatric endocrinology were included: 70 non-PCOS controls, 115 untreated PCOS, 9 PCOS + obesity treated with COCP, and 6 PCOS + obesity treated with metformin. 11-Hydroxyandrostenedione (11-OHA4), 11-hydroxytestosterone (1-OHT), 11-ketotestosterone (11-KT), and testosterone were measured with liquid chromatography-tandem mass spectrometry. Data between 1) untreated PCOS and controls and 2) untreated PCOS and the 2 treatment groups were compared.
Results: Untreated girls with PCOS had higher 11-OHA4 ( = .003) and 11-OHT ( = .005) compared to controls, but not 11-KT ( = .745). Elevated 11-OHA4 remained statistically significant after controlling for obesity. Testosterone better predicted PCOS status compared to 11-oxyandrogens (receiver operating characteristic curve analysis: 11-OHA4 area under the curve [AUC] = 0.620, 11-OHT AUC = 0.638; testosterone AUC = 0.840). Among untreated PCOS patients, all 3 11-oxyandrogens correlated with hirsutism severity. 11-KT ( = .039) and testosterone ( < .006) were lower in those on COCP treatment compared to untreated PCOS. Metformin treatment had no effect on 11-oxyandrogens, although testosterone was lower ( = .01).
Conclusion: Although 11-oxyandrogens do not aid in the diagnosis of PCOS, they relate to excess hair growth. COCP treatment may related to 11-KT; however, further work is needed to determine causality, relationship with metabolic outcomes, and the clinical utility of measuring these androgens in PCOS.

The effect of anterior disc displacement with polycystic ovarian syndrome on adolescent condylar bone remodeling.
BMC Oral Health
January 2025

Background: Adolescent females have a high prevalence of temporomandibular joint (TMJ) anterior disc displacement (ADD), which can lead to condylar resorption and dentofacial deformity. Polycystic ovarian syndrome (PCOS) is a common endocrine disorder that disrupts bone metabolism. However, the effects of PCOS on bone remodeling especially after disc repositioning (DR) surgery are not well understood.

Background: Insulin resistance (IR) is considered a major driver of the pathophysiology of polycystic ovary syndrome (PCOS), mediating the progression of hyperandrogenism and metabolic and reproductive dysfunction in patients with PCOS. Early detection of the risk of concurrent IR is essential for women with PCOS. To address this need, this study developed a predictive nomogram for assessing the risk of IR in women with PCOS, aiming to provide a tool for risk stratification and assist in clinical decision-making.

Article Synopsis
- - This study explored how leaf extracts could help improve symptoms of polycystic ovary syndrome (PCOS) in Wistar rats induced by letrozole.
- - Treatment with leaf extracts significantly improved hormonal balance and regularity of the estrus cycle, and showed a positive effect by reducing testosterone and increasing estradiol levels.
- - The extract also normalized several important gene expressions linked to metabolic and hormone regulation, indicating its potential as a promising treatment for PCOS.
Unexpected delivery: cryptic pregnancy.

Cryptic pregnancy was first described in the early 17th century and occurs when the pregnant person is unaware of their pregnant state and discovers this late in pregnancy or when labour starts. Historically, the term 'concealed pregnancy' has been used synonymously. In a concealed pregnancy, the patient is aware of their pregnancy but chooses to hide it.

In Brief: The hypoglycemic drug metformin has shown reproductive effects in women, although its mechanism of action is not fully understood. In this study, we demonstrate the direct effects of metformin on the ovary of healthy mice, with no alterations in fertility.
Abstract: Metformin is a hypoglycemic drug widely used in type-2 diabetes (T2D) patients.
