Introduction: Assessment of ovarian features are discouraged in the diagnosis of PCOS in adolescence owing to a lack of normative data and historically poor image quality via transabdominal ultrasonography. However, we have recently shown that ovarian morphology is adequately resolved via transabdominal ultrasound in adolescents and that follicle number and ovarian size reflect circulating AMH within the first gynecological year. Whether ovarian features at this early gynecological stage predict menstrual cycle status at two-years post-menarche (2YR-PM) is unknown. 

Methods: Menstrual records of 19 adolescent females who were evaluated at 6-10 months post-menarche (PM) were collected as a part of a prospective cohort study. Menstrual cycle status was determined at 2YR-PM as regular (three previous inter-menstrual intervals within 21-45 days) or irregular (at least one of the three previous inter-menstrual intervals <21 or >45 days). At 6-10 months PM, participants underwent a fasting blood draw, anthropometry, bioimpedance, and a transabdominal ultrasound of the ovaries. Differences in reproductive and metabolic features at 6-10 months PM were contrasted in those who were regular versus irregular at 2YR-PM via Mann-Whitney U-Tests. Whether reproductive features assessed at 6-10 months PM predicted menstrual cycle status at 2YR-PM was determined via logistic regression analyses.

Results: At 2YR-PM, 6/19 adolescents met the criteria for regular menstrual cycles and 13/19 met the criteria for irregular menstrual cycles. There were no differences in the metabolic profile nor in clinical or biochemical measures of androgens status at 6-10 months PM between those who ultimately achieved regular vs irregular menstrual cycles (P>0.05). However, adolescents with irregular menstrual cycles at 2YR-PM had higher LH concentrations (4.8 [3.5-5.5] vs 3.0 [2.4-3.8] mIU/mL; P=0.025), AMH (5.6 [5.1-7.3] vs 3.0 [1.6-4.5] ng/mL, P=0.023), and tended to have higher numbers of antral follicles 2-5mm in diameter (FNPO 2-5mm) (19 [14-25] vs 10 [7-16], P=0.06) at 6-10 months PM. The likelihood of regular menstrual cycles at 2YR-PM decreased with higher AMH (Odds Ratio 0.49 [0.24-0.98], P=0.01), LH (OR: 0.33 [0.13-1.09], P=0.019) and tended to decrease with greater FNPO 2-5mm (OR: 0.89 [0.76-1.03], P=0.05) at 6-10 months PM. 

Conclusion: Ovarian features and serum LH may serve as early, clinically feasible biomarkers of future persistent menstrual irregularity with defective folliculogenesis preceding metabolic and androgenic derangements  in the timeline to aberrant reproductive maturation. Whether adolescents with persistent menstrual irregularity meet criteria for PCOS will be determined upon conclusion of the cohort study.

Reproductive features captured within the first gynecological year predict persistent menstrual irregularity at two years post-menarche

Objective: Polycystic ovary syndrome (PCOS) is a common condition with endocrine-metabolic dysfunction, and is highly heritable. Yet, there is limited research on how offspring are affected, and the age of onset, if any. We established a cohort of women with PCOS and matched controls along with their offspring to evaluate the effects of maternal PCOS on the offspring, as well as any differential impact between boys and girls. 
Methods: Among Chinese women from our PCOS registry (diagnosed based on the 2003 Rotterdam diagnostic criteria), we invited those who have children to participate in a follow-up study, and evaluated both the mothers and their sons (PCOSs) and daughters (PCOSd). For controls, we recruited women from the Hyperglycaemia and Adverse Pregnancy Outcome (HAPO) Study, who did not have PCOS or GDM, together with their sons (Cs) and daughters (Cd), for comparison. All offspring aged 15-25 years were included in the current analysis, and all have undergone a detailed assessment with questionnaire, anthropometric assessment, a standardized 75g OGTT for glycemic status evaluation and biochemical tests. Difference between groups were evaluated using independent sample t-test or Mann-Whitney U test for continuous variables, while Chi-square (X2) or Fisher’s exact tests were used for categorical variables. 
Result: A total of 21 PCOSs and 18 PCOSd (mean age 19.86 ± 3.98 and 18.33 ± 2.30, respectively) as well as 26 Cs and 45 Cd (mean age 17.27 ± 0.67 and 17.58 ± 0.84, respectively) were recruited to date. We noted a high prevalence of menstrual irregularity in PCOSd when compared with Cd (PCOSd: 8/18 (44.4%) vs Cd: 7/44 (15.9%), p<0.005). We also found that the frequency of elevated androgen levels was 8/18 (44.4%) and 11/33 (33.3%) in PCOSd and Cd, respectively (p=0.433). PCOSd were significantly more centrally obese than Cd (PCOSd: 5/18 (27.8%) vs Cd: 2/45 (4.4%), p=0.007). Yet, such significant difference was not observed when comparing between PCOSs and Cs. There was no significant difference in the prevalence of dyslipidemia (PCOSs: 13/21 (61.9%) vs Cs: 9/21 (42.9%), p=0.217; PCOSd: 3/18 (16.7%) vs Cd: 5/34 (14.7%), p=0.852), hypertension (none for both PCOSs and Cs; PCOSd: 1/18 (5.6%) vs Cd: 1/45 (2.2%), p=0.465) and metabolic syndrome (AHA/NHLBI) (PCOSs: 3/21 (14.3%) vs Cs: 0/26; Pd: 2/18 (11.1%) vs Cd: 0/45) in both gender between offspring of mothers with and without PCOS. There is a trend towards higher frequency of glucose abnormalities when comparing PCOSd vs Cd (PCOSs: 2/21 (9.5%) vs Cs: 1/21 (4.8%), p=0.549; PCOSd: 4/18 (22.2%) vs Cd: 2/34 (5.9%), p=0.079), although there was no significant difference.
Conclusion: PCOSd have increased risk of menstrual irregularity and central obesity compared to Cd. No difference in cardiometabolic traits were observed between PCOSs and Cs. Our preliminary results shed some light on the potential long-term cardiometabolic burden on PCOSd. 


Sexual dimorphism in cardiometabolic risk in offspring of mothers with PCOS

Natural history of PCOS

In women with PCOS receiving controlled ovarian stimulation for in vitro fertilization (IVF), follicular fluid and granulosa cells are dysfunctional, with hundreds of transcripts, proteins, lilpids and metabolites that differ significantly from controls with non-ovarian causes of infertility. However,  there is no evidence that oocytes are compromised: the proportion of metaphase II oocytes, the rate of development to blastocyst and the prevalence of aneuploid embryos are unchanged. Endometrial proteome is altered but receptivity is not affected in IVF treatments, where the implantation rates of single 'ideal' blastocysts are similar in PCOS and controls. During ovarian stimulation for IVF, protocols that use pituitary downregulation with GnRH antagonist followed by triggering with GnRH agonist are safer (lower incidence of ovarian hyperstimulation syndrome) and equally effective (same pregnancy rates) compared with long protocols that use GnRH agonist for pituitary downregulation and hCG for ovulation triggering. FSH receptor gene polymorphisms may affect ovarian response to exogenous FSH, but the clinical usefulness of this information to plan IVF treatments of women with PCOS is still uncertain. For women with PCOS treated with IVF, frozen embryo transfer is better than fresh embryo transfer. When preparing the endometrium for frozen embryo transfer, pituitary downregulation with GnRH agonist does not increase the odds of a live birth. Progestins are better than COC to induce menses before starting an IVF cycle in women with PCOS. Insulin sensitizers or weight reduction do not seem to improve IVF outcomes.

IVF and PCOS

PCOS is though to stem from prenatal exposures and seems to translate into increased comorbidity risk. The health insults, however, vary depending on the age. The presentation will go through the health risks related to PCOS over the lifespan.
