Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Diminished ovarian reserve (DOR), a pathological condition of reduced quantity and quality of oocytes, has severe impairment on women fertility. Some women experience DOR may develop into premature ovarian insufficiency (POI), which defined as a cessation of function of ovaries in women younger than 40 years old. The pathogenesis of DOR is multiple and the etiology of most DOR remains obscure. Genetic factors, including chromosome abnormality, genetic variation, and non-coding RNA abnormal regulation are considered the major mechanisms of DOR. More than 12 gene mutations, detected by whole-exome sequencing (WES), have been implicated as potential causes of DOR. However, we have found that coding gene mutation detected by WES may only account for a small part of DOR. Whole-genome sequencing (WGS) has been developing into an important strategy for identifying exons, introns and mitochondrial DNA mutation. However, the application of WGS is still lacking in detecting pathogenic genes of DOR. Therefore, this study intends to explore the possible pathogenic genes by WGS in order to deeply and comprehensively understand the pathogenic mechanism of DOR.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 40 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Probability Sample

Study Population

The two groups of this study consist of DOR patients and women with normal ovarian reserve.

Description

Inclusion Criteria:

DOR group:

  1. age between 18 and 40 years;
  2. number of oocytes obtained in previous ovarian stimulation cycles ≤3;
  3. bilateral ovarian antral follicle count (AFC) < 5-7;
  4. serum anti-Mullerian hormone (AMH) <0.5-1.1ng/ml.

Control group:

  1. age between 18 and 40 years;
  2. bilateral AFC ≥8;
  3. serum AMH ≥1.2ng/ml;
  4. regular menstrual cycles occurring every 25-35 days.

Exclusion Criteria:

The exclusion criteria of the two groups were:

  1. an abnormal karyotype;
  2. a history of other endocrine diseases such as polycystic ovary syndrome, hyperprolactinemia and hyperthyroidism;
  3. a history of radiotherapy, chemotherapy and ovarian surgery.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
DOR group
Genomic DNA will be extracted from peripheral blood leukocytes to perform whole-genome sequencing in participates with diminished ovarian reserve.
Other: whole-genome sequencing
Whole-genome sequencing will be preformed for each participate to explore the potential disease-causing genes of DOR.
Control group
Participants with normal ovarian reserve will be recruited as control group and peripheral blood leukocytes genomic DNA will be extracted to perform whole-genome sequencing.
Other: whole-genome sequencing
Whole-genome sequencing will be preformed for each participate to explore the potential disease-causing genes of DOR.
