Objective: To determine the cumulative incidence of live delivery in women who underwent reversal of tubal sterilization.
Design: Population-based retrospective cohort study.
Setting: Hospitals in Western Australia.
Patient(s): All women aged 20-44 years, with a history of hospital admission for tubal sterilization, who subsequently underwent reversal of sterilization during the period 1985 to 2009 in Western Australia (n = 1,898).
Intervention(s): Data regarding reversal of sterilization and prior tubal sterilization were extracted from routinely collected administrative hospital separation records, until commencement of IVF treatment.
Main Outcome Measure(s): First live-delivery rates.
Result(s): There were 969 first live deliveries observed during the study period. The overall cumulative live-delivery rate was 20% (95% confidence interval [CI] 18-23) within the first year after reversal, 40% (95% CI 38-42) at 2 years, 51% (95% CI 48-53) at 5 years, and 52% (95% CI 50-55) at 10 years. The 5-year cumulative live-delivery rate was significantly lower in women who were aged 40-44 years (26%) compared with younger women (aged 20-29, 30-34, and 35-39 years) (50%, 56%, and 51%, respectively).
Conclusion(s): Women undergoing reversal of sterilization before they reach age 40 years have at least a 50% chance of delivering a live baby within the next 5 years. Up to that age, there is no significant difference in live deliveries. The live-delivery rate halves after the age of 40 years.

Objective: Surgical sterilization, including vasectomy in males and tubal ligation in females, is a highly effective but underutilized contraception method. Adoption rates vary globally mostly due to misconceptions by both the general public and practicing physicians. Our survey aims to explore physicians' knowledge, attitudes and beliefs about surgical sterilization techniques in Lebanon.

Study Question: Does a human fallopian tube (HFT) organoid model offer a favourable apical environment for human sperm survival and motility?
Summary Answer: After differentiation, the apical compartment of a new HFT organoid model provides a favourable environment for sperm motility, which is better than commercial media.
What Is Known Already: HFTs are the site of major events that are crucial for achieving an ongoing pregnancy, such as gamete survival and competence, fertilization steps, and preimplantation embryo development. In order to better understand the tubal physiology and tubal factors involved in these reproductive functions, and to improve still suboptimal in vitro conditions for gamete preparation and embryo culture during IVF, we sought to develop an HFT organoid model from isolated adult stem cells to allow spermatozoa co-culture in the apical compartment.
Tubal Sterilization And Vasectomy Increased Among US Young Adults After The Supreme Court Decision In 2022.

Young adults' access to contraception is shifting after the June 2022 United States Supreme Court decision. This concurrent mixed-methods study measured young adults' use of and perceptions about tubal sterilization and vasectomy after the leaked opinion in May 2022. Using national-level medical claims data from IQVIA, we conducted difference-in-differences analyses of tubal sterilizations and vasectomies by age and state policy; using open-text survey responses from national MyVoice surveys in 2022 and 2023, we thematically analyzed young adults' perspectives.

Article Synopsis
- There is an increasing interest in vasectomies following the Supreme Court's Dobbs decision, highlighting their safety and cost-effectiveness compared to tubal sterilization.
- Health care providers from Title X-funded clinics were interviewed to understand the cultural, gender, and political influences on men's decisions to seek vasectomies.
- Key barriers identified included income challenges, language barriers, medical distrust, and traditional gender roles, but many men expressed a strong desire to take responsibility for contraception and contribute to reproductive health equity.
Article Synopsis
- Serous tubal intraepithelial carcinoma (STIC) lesions are precursors to high-grade serous ovarian carcinomas, which have the highest mortality rates among gynecologic cancers, particularly affecting women with hereditary risk factors.
- A 38-year-old woman of Nepalese descent was found to have a STIC lesion during an opportunistic salpingectomy performed for sterilization, highlighting the potential risks even in patients considered average risk for ovarian cancer.
- While the SEE-FIM protocol, which is more sensitive for detecting STIC lesions, is typically not applied to average risk patients, implementing it could reduce missed diagnoses, although the costs and effort involved remain uncertain, especially among underrepresented populations.
