Introduction: Polycystic ovarian syndrome (PCOS) is a complex endocrine disorder that significantly affects adolescent girls, particularly those with overweight or obesity. However, data examining the determinants and metabolic profiles of PCOS among adolescents with overweight and obesity remain limited, especially in Malaysia. This protocol describes a case-control study investigating the cardiometabolic, dietary, and psychosocial determinants of PCOS among adolescents with overweight and obesity. Methodology: This study is designed as a case-control study involving adolescent girls aged 13–16 years with a body mass index z-score >+1 standard deviation. Cases are defined as adolescent girls with a confirmed diagnosis of PCOS based on the recommendations of the 2017 International Consortium of Paediatric Endocrinology (ICPE), while controls are those who do not meet the diagnostic criteria for PCOS. A total sample size of 440 participants is required. Participants will be recruited from 22 secondary schools selected from a list of schools in Kuala Lumpur. Data on sociodemographic characteristics, psychosocial health, physical activity, and dietary intake will be collected using structured questionnaires. Blood samples will be obtained and analyzed for diagnostic testing (free testosterone), exclusion tests (thyroid-stimulating hormone, folliclestimulating hormone, luteinizing hormone, estradiol, prolactin, and dehydroepiandrosterone sulfate), and biochemical parameters (liver function tests, lipid profile, hemoglobin A1c, fasting glucose, fasting insulin, and inflammatory markers). Results: The study is expected to generate comprehensive data on the cardiometabolic, dietary, and psychosocial determinants of PCOS among adolescents with overweight and obesity. The findings will inform early screening strategies and targeted interventions aimed at reducing long-term reproductive and cardiometabolic complications. Conclusion This protocol outlines a structured approach to investigating PCOS in adolescence and addresses current gaps in early identification and risk stratification among highrisk populations.

Introduction: Polycystic ovary syndrome (PCOS) is the most common cause of hyperandrogenism in women of reproductive age. However, several endocrine disorders, particularly Cushing disease (CD), can closely mimic the clinical, biochemical, and radiological features of PCOS. This overlap may lead to misdiagnosis and delayed recognition of hypercortisolism, with significant metabolic and reproductive consequences. Case: We report a 24-year-old female with young-onset diabetes mellitus who was referred for endocrine co-management during admission for recurrent mons pubis and labial abscesses with poorly controlled glycemia. She had a 5-year history of progressive hirsutism, oligomenorrhoea, scalp hair loss, significant weight gain, and insulin resistance, and had previously been labelled as having PCOS during adolescence, with subsequent default of follow-up. On examination, she was obese (body mass index 33 kg/ m²) with plethoric facies, acanthosis nigricans, proximal myopathy, and hirsutism (Ferriman–Gallwey score 10), without overt virilization or acromegalic features. Biochemical evaluation demonstrated severe hyperandrogenism with markedly elevated total testosterone (7.05 nmol/L), suppressed gonadotropins, and adrenocorticotropic hormone (ACTH)-dependent hypercortisolism. Cortisol failed to suppress on low-dose dexamethasone testing, and 24-hour urinary free cortisol was markedly elevated (>4,900 nmol/24 h). Pelvic ultrasonography and computed tomography imaging showed polycystic ovarian morphology without evidence of an ovarian mass. Pituitary magnetic resonance imaging revealed a small right-sided pituitary microadenoma measuring 2.6 × 3.7 mm. Inferior petrosal sinus sampling demonstrated a central-to-peripheral ACTH gradient with adequate prolactin ratios, confirming pituitary CD. Conclusion This case highlights how Cushing disease can closely mimic PCOS, including polycystic ovarian morphology and hyperandrogenism. Progressive symptoms, severe biochemical androgen excess, and marked insulin resistance should prompt evaluation for secondary causes of hyperandrogenism, particularly hypercortisolism, to avoid delayed diagnosis and prolonged morbidity.

Introduction: Primary ovarian pregnancy is a rare ectopic gestation (<1% of ectopic pregnancies), usually presenting with first-trimester rupture. Progression to term with live birth is exceedingly rare and requires pathologic confirmation to exclude secondary implantation. Case Presentation: A 32-year-old multigravida underwent exploratory laparotomy for suspected ectopic pregnancy at term. A placenta-bearing mass involving the right ovary was identified, with a grossly normal ipsilateral fallopian tube. Right oophorectomy was performed, delivering a live female infant weighing 3,060 grams with Apgar scores of 8 and 9. Gross examination showed a large hemorrhagic placenta-like mass replacing the ovary with peripheral residual ovarian tissue. Histology revealed mature chorionic villi with syncytial knots, stromal fibrosis, calcifications, and abundant intervillous blood, directly implanted within ovarian stroma containing luteinized cells and corpus albicans remnants, with no tubal or endometrial tissue identified. Discussion: Advanced primary ovarian pregnancy is extremely rare and may mimic secondary abdominal or tubal implantation. Diagnosis relies on the Spiegelberg criteria, including an intact ipsilateral fallopian tube, ovarian location of the gestation, attachment through the ovarian ligament, and histologic demonstration of chorionic villi within ovarian stroma, confirming true ovarian implantation. Conclusion Clinical, gross, and microscopic findings fulfill the Spiegelberg criteria, confirming primary ovarian pregnancy. This rare term pregnancy highlights the crucial role of surgical pathology in establishing the definitive diagnosis and excluding secondary implantation.

Nongestational ovarian choriocarcinoma (NGOC) is a sporadic and aggressive malignant germ cell tumor, with fewer than 100 cases reported in the literature. We present the case of a 28-year-old woman diagnosed with NGOC, who underwent fertility-sparing surgery and adjuvant bleomycin, etoposide, and cisplatin chemotherapy, followed by a recurrence managed with the second-line chemotherapy and radiotherapy. This report highlights the diagnostic challenges, unique β-human chorionic gonadotropin profile, disease course, and treatment response.

OBJECTIVES: To evaluate the association of GGN repeat polymorphism of androgen receptor (AR) with ovarian reserve and ovarian response in controlled ovarian stimulation (COS). METHODS: This genetic association study was conducted among a total of 361 women aged ≤40 years with basal FSH≤12 U/L undergoing the GnRH-agonist long protocol for COS in a university-affiliated IVF center. GGN repeat in the AR gene was analyzed with Sanger sequencing. The primary endpoint was the number of antral follicle counts (AFCs), and the secondary endpoints were stimulation days, total dose of gonadotropin (Gn) used, total number of retrieved oocytes, ovarian sensitivity index, and follicular output rate. RESULTS: The GGN repeat in exon 1 of the AR gene ranged from 13 to 24, and the median repeat length was 22. Based on the genotypes (S for GGN repeats <22, L for GGN repeats ≥22), the patients were divided into 3 groups: SS, SL, and LL. Generalized regression analysis indicated that the number of AFCs in group SS was significantly lower than those in group SL (adjusted β=1.8, 95% CI: 0.2-3.4, P=0.024) and group LL (adjusted β=1.5, 95% CI: 0.2-2.7, P=0.021). No significant difference was observed in the number of AFCs between group SL and group LL (P>0.05). Generalized regression analysis indicated no significant differences in ovarian stimulation parameters among the 3 groups, either before or after adjusting for confounding factors (P>0.05). CONCLUSIONS GGN repeat length on the AR gene is associated with AFC but not with ovarian response in Chinese women, indicating that AR gene polymorphisms may affect ovarian reserve.

Polycystic ovary syndrome (PCOS) is the predominant cause of subfertility in reproductive-aged women; however, its pathophysiology remains unknown. Neurotensin (NTS) is a member of the gut-brain peptide family and is involved in ovulation; its relationship with PCOS is unclear. Here, we found that NTS expression in ovarian granulosa cells and follicular fluids was markedly decreased in patients with PCOS. In the in vitro culture of cumulus-oocyte complexes, the neurotensin receptor 1 (NTSR1) antagonist SR48692 blocked cumulus expansion and oocyte meiotic maturation by inhibiting metabolic cooperation and damaging the mitochondrial structure in oocytes and surrounding cumulus cells. Furthermore, the ERK1/2-early growth response 1 pathway was found to be a key downstream mediator of NTS/NTSR1 in the ovulatory process. Animal studies showed that in vivo injection of SR48692 in mice reduced ovulation efficiency and contributed to irregular estrus cycles and polycystic ovary morphology. By contrast, NTS partially ameliorated the ovarian abnormalities in mice with dehydroepiandrosterone-induced PCOS. Our findings highlighted the critical role of NTS reduction and consequent abnormal NTSR1 signaling in the ovulatory dysfunction of PCOS, suggesting a potential strategy for PCOS treatment.

BACKGROUND

Polycystic ovarian syndrome (PCOS) is a common gynecologic endocrine disorder affecting between 2.2% and 26% of the population. It is typically characterized by hirsutism and signs of ovulatory dysfunction. Hirsutism is defined as the presence of excess body or facial terminal hair growth in females, following a male-like pattern. It is diagnosed using visual assessment methods, such as the modified Ferriman–Gallwey (mFG) scoring system, and biochemical tests, including measurements of total testosterone (tT) and the free androgen index (FAI).

The general objective of the study is to identify the correlation of visual scoring with the biochemical evaluation of hirsutism. Specific objectives include (1) to describe the visual and biochemical scores of hirsutism in PCOS patients and (2) to determine a cutoff score for the visual scoring of hirsutism among Filipinos.

This is a cross-sectional study done in a tertiary hospital. Ethical approval was obtained for this study. Patients who satisfied the inclusion criteria were included in the study. Age, height, weight, body mass index (BMI), and OB score were noted. Visual scoring for hirsutism using the mFG scoring system was performed. Blood extraction was done for testosterone and sex hormone-binding globulin tests. FAI was then computed and correlated with the mFG scores.

A total of 52 patients were identified. A positive correlation is noted between the mFG with testosterone and FAI. A positive correlation was also noted between the BMI with testosterone and FAI. An mFG value of >4 is an acceptable cutoff for Filipinos.

The study showed as the mFG score increases, FAI and tT levels also increase. It was also noted that as BMI increases, the FAI and tT levels are also expected to increase. It can also be concluded that a lower mFG cutoff value, >4, is applicable for Filipinos.

This is a case of a 33-year-old, G3P3(3003) female patient with a clinical presentation of vaginal bleeding associated with on and off hypogastric pain. The patient was diagnosed and managed as a case of tubo-ovarian abscess and subsequently underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy (TAHBSO). Microscopic sections of both ovaries, however, showed dual population of tumor cells composed of medium-sized, mononucleated cells admixed with multinucleated giant cells with marked pleomorphism, extensive hemorrhage and necrosis. Immunohistochemistry studies using beta-hCG was diagnostic of ovarian choriocarcinoma, favoring non-gestational in origin. Classification of non-gestational choriocarcinoma (NGOC) was established using diagnostic criteria for NGOC established by Saito et al., and Mangla et al. DNA analysis, however, remains to be the gold-standard for differentiating between gestational (GOC) and non-gestational (NGOC) etiology.

BACKGROUND AND OBJECTIVE

Polycystic ovarian syndrome (PCOS) is a complex disease associated with endometrial lesions. Local data on endometrial findings associated with PCOS are limited. This study aimed to determine the local prevalence and spectrum of endometrial findings and their association with clinical factors among Filipino women with PCOS.

This is a retrospective review of women aged 18–40 years old seen at a local tertiary hospital from January 2016 to December 2020 with ultrasound findings of polycystic ovaries based on Rotterdam criteria. The clinical data and ultrasound findings/impressions were reviewed. Histopathologic results when available were retrieved. Data were analyzed using descriptive statistics; abnormal endometrial findings were associated with clinical factors using binary logistic regression analysis.

A total of 177 women were included in the study, and 39 (22%) had abnormal endometrial findings by ultrasound including thickened endometrium (14.7%), polyp (5.1%), submucous myoma (1.1%), and malignancy (1.1%). Ultrasound findings that were significantly common with abnormal endometrium included thickening, nonuniform echogenicity, and the presence of vascularity. Irregular menses were more common in those with a normal endometrium, while heavy menses predominated in those with an abnormal endometrium, with statistically significant differences ( <0.001). The overall prevalence of obesity was 19.77%, but no clinical diseases were found significantly associated with abnormal endometrium. The prevalence of endometrial polyp and malignancy as confirmed by histopathology were 5.1% and 1.69%, respectively. No endometrial hyperplasia cases were reported.

Abnormal endometrial findings were relatively common among cases with polycystic ovaries, and most often, cases present with heavy menstrual bleeding. However, no predictable clinical factor can help identify PCOS patients with abnormal endometrial findings. Although malignancy was less common in the age group included in this study, the presence of abnormal sonographic findings would warrant further evaluation.

OBJECTIVE: To explore the mechanism of acupuncture on improving ovarian hypofunction in aged rats from two perspectives: the overall regulation of the hypothalamic-pituitary-ovarian (HPO) axis and the local ovarian follicle stimulating hormone (FSH)/cyclic adenosine monophosphate (cAMP) signaling pathway. METHODS: Six 3-month-old female SPF-grade Sprague-Dawley (SD) rats were selected as the blank group. Another twelve 9-month-old female SD rats were randomly divided into a model group and an acupuncture group, with six rats in each. The acupuncture group received acupuncture at "Baihui" (GV20), "Guanyuan" (CV4), and bilateral "Ciliao" (BL32) for 20 min per session, once every other day, for a total of 10 sessions. Vaginal smear tests were performed daily to observe the estrous cycle of the rats. Ovarian morphology was observed using HE staining, and follicles at various stages were counted. ELISA was used to detect levels of serum FSH, luteinizing hormone (LH), estradiol (E₂), anti-müllerian hormone (AMH), hypothalamic gonadotropin-releasing hormone (GnRH), pituitary FSH and LH, and ovarian cAMP. Immunohistochemistry and Western blot were used to detect the protein expression of ovarian cAMP protein kinase catalytic subunit, FSH receptor (FSHR), and P450. Real-time quantitative PCR was used to measure mRNA expression levels of FSHR and P450 in ovarian tissue. RESULTS: Compared with the blank group, the model group showed an increased rate of estrous cycle disorder (P<0.01), reduced granulosa cell layers with blurred boundaries and disordered arrangement, decreased numbers of developing follicles at all stages, and increased numbers of atretic follicles (P<0.01); the serum levels of FSH and LH were increased (P<0.01), while E₂ and AMH levels were decreased (P<0.01); the hypothalamic GnRH and pituitary FSH and LH levels were elevated (P<0.01), and ovarian cAMP level was decreased (P<0.01); the positive expression and protein expression of ovarian P450, cAMP protein kinase catalytic subunit, and FSHR were reduced (P<0.01), and ovarian FSHR and P450 mRNA expression was decreased (P<0.01). Compared with the model group, the acupuncture group showed a reduced rate of estrous cycle disorder (P<0.01), clear granulosa cell margins, increased numbers of primordial and secondary follicles, and decreased numbers of atretic follicles (P<0.01); the serum FSH and LH levels were decreased (P<0.01, P<0.05), while E₂ and AMH levels were increased (P<0.05, P<0.01); the hypothalamic GnRH and pituitary FSH and LH levels were decreased (P<0.01, P<0.05), and ovarian cAMP level was increased (P<0.01); the positive expression and protein expression of ovarian P450, cAMP protein kinase catalytic subunit, and FSHR were elevated (P<0.01), and ovarian FSHR and P450 mRNA expression was increased (P<0.01). CONCLUSION Acupuncture could delay ovarian hypofunction in aged rats, possibly through regulating the HPO axis and the FSH/cAMP signaling pathway.
