A Large-scale, Prospective Cohort Study Was Conducted to Explore the Association Between Environmental Exposure and Behavioral Factors and Infertility (the Success Rate of Assisted Reproductive Technology)

8 giugno 2026 aggiornato da: The Third Xiangya Hospital of Central South University

The aim is to explore the reasons for the failure of assisted reproductive technology (ART) in infertile patients in Hunan Province and seek ways to improve the success rate of ART. The study will focus on how environmental exposure (such as environmental pollutants related to plastic products) and lifestyle and social factors affect the success rate of ART in infertile patients.

In order to explore these issues in depth, the study plans to collect 5,000 samples (male: female ratio 1:1), screen the research subjects from infertile patients who visited Xiangya Third Hospital in Changsha, Hunan Province, and establish a large-scale, prospective infertility patient cohort. By collecting multi-faceted information of the research subjects, including sociodemographic characteristics, lifestyle, basic health status, etc., and conducting long-term follow-up observations, the ART live birth situation of infertile patients is analyzed.

In terms of research methods, a multivariate analysis method will be used to explore the association between various factors and ART success rate, and a risk prediction model will be constructed. In addition, the study also hopes to clarify the specific reasons for the failure of infertile patients to receive ART, provide a scientific basis for clinical decision-making, and provide guidance for the formulation of environmental protection policies and the improvement of public reproductive health literacy.

In general, this study, through a large-scale, prospective cohort study, deeply explores the various factors that affect the success rate of ART in infertile patients, and strives to build a risk prediction model in order to improve the success rate of ART and bring more hope to infertile families.

Descrizione dettagliata

Purpose of the study: This study aims to clarify the reasons for the failure of assisted reproductive technology (ART) in infertile patients in Hunan Province, to achieve early identification and prediction of risk factors, and thus improve the success rate of ART.

Experimental design:

Prospective cohort study, 5,000 people are planned to be collected (male-female ratio 1:1).

Experimental process:

  1. Establish a large-scale, prospective infertility patient cohort to provide basic data for studying the relationship between environmental factors, biological factors and social factors and ART success rate.
  2. Analyze the relationship between exposure (internal exposure) to environmental factors (such as environmental pollutants related to plastic products) and infertility (ART success rate), and provide a scientific basis for the formulation of environmental protection policies.
  3. Explore the impact of lifestyle and social factors on the ART success rate of infertile patients, and provide guidance for improving the public's reproductive health literacy.
  4. Construct a prediction model for adverse pregnancy outcomes of infertility ART, and provide new ideas for improving the ART success rate of infertile patients.

Inclusion criteria:

(1) A. Women aged 18 to 46 years old using their own eggs or men aged 18 to 55 years old using their own sperm; B. Patients who meet the diagnostic criteria for infertility; C. A clear history of persistent infertility; D. Voluntary participation in the project and signing of the informed consent form;

Exclusion criteria:

(1) A. People with any of the following contraindications to ARTs: a. Impairment of sperm and egg combination caused by fallopian tube factors in the female. b. Acute infection of the reproductive and urinary system or sexually transmitted diseases in the female. c. Genetic diseases, serious physical diseases, and mental and psychological disorders in the female. d. History of birth of babies with congenital defects confirmed to be caused by the female. e. The female is exposed to teratogenic radiation, poisons, and drugs and is in the period of action. f. The female has bad habits such as alcoholism and drug abuse. B. People who have any of the following contraindications to ARTs for first-generation and second-generation test-tube babies: a. Any party who provides gametes suffers from acute infection of the reproductive and urinary systems and sexually transmitted diseases, or has bad habits such as alcoholism and drug abuse. b. Any party who provides gametes is exposed to teratogenic radiation, poisons, and drugs and is in the period of action. c. The couple who receive embryo donation/egg donation suffers from acute infection of the reproductive and urinary systems and sexually transmitted diseases, or has bad habits such as alcoholism and drug abuse. d. The woman's uterus does not have the function of pregnancy or has a serious physical disease that cannot withstand pregnancy. C. No embryo transfer is performed after egg retrieval; D. Frozen embryo transfer is received more than 180 days after egg retrieval;
