30-Second Takeaway
- WHO issues global infertility guideline emphasizing equitable access, streamlined workup, and patient-centered counseling.
- Low-dose COCPs did not worsen metabolic syndrome in obese, hyperandrogenic PCOS and improved adiposity measures.
- Prior in-labor, especially full-dilation cesarean, meaningfully increases subsequent mid-trimester loss and spontaneous preterm birth risk.
- Sentinel node biopsy alone appears oncologically safe for carefully selected early cervical cancer, supporting nodal surgery de-escalation.
- Home-based methotrexate/folinic acid for low-risk GTN matches hospital outcomes with longer remission time but full survival.

Infertility, PCOS, cervical disease, and gynecologic oncology: concise updates with immediate practice implications
New WHO infertility guideline prioritizes equitable access, rational testing, and patient-centered care
The WHO infertility guideline provides 40 recommendations and 6 good practice statements across prevention, diagnosis, and treatment of infertility. It emphasizes selective use of diagnostic tests, structured listening to individuals and couples, shared decision-making, and systematic documentation of outcomes. Prevention recommendations focus on fertility information, STI risk reduction, lifestyle factors, and tobacco cessation. Diagnostic guidance addresses ovulatory dysfunction, tubal disease, uterine cavity abnormalities, and timing of semen analysis in males.
COMET-PCOS: COCPs do not worsen metabolic syndrome in obese, hyperandrogenic PCOS
In COMET-PCOS, 240 women aged 18–40 years with obesity and hyperandrogenic PCOS were randomized to COCP, metformin, or combination for 24 weeks. Metabolic syndrome prevalence at study end was similar across groups, with no significant treatment-related differences (adjusted p = 0.26). Contrary to concern, low-dose COCP use was associated with reductions in waist circumference, BMI, and android fat mass. These data suggest low-dose COCPs are metabolically acceptable for short-term management in obese women with hyperandrogenic PCOS.
In-labor and full-dilation cesarean elevate subsequent spontaneous preterm birth risk
This review highlights that cesarean deliveries performed in labor, especially at full dilatation, increase later mid-trimester loss and spontaneous preterm birth risk. Reported odds ratios reach up to 3.42 versus prior vaginal birth, with particularly high risk after full dilatation cesarean. Preterm births following in-labor cesarean tend to be recurrent and challenging to prevent with standard interventions. The authors call for risk tools, assessment of cesarean scar characteristics, and trials of progesterone and abdominal cerclage in this subgroup.
Sentinel node biopsy alone shows excellent survival in early cervical cancer
Using National Cancer Database data, 465 patients with early cervical cancer undergoing radical hysterectomy and sentinel node biopsy were analyzed. Patients had stage IA1 with LVSI, IA2, IB1, or IIA1 disease with tumors ≤3 cm, mirroring PHENIX-I criteria. Five-year overall survival was 98.6% with sentinel node biopsy alone and 96.8% with additional lymphadenectomy (P = .69). Findings support omitting full lymphadenectomy in appropriately selected early-stage patients, pending further validation of long-term outcomes.
