Featured NICHD Clinical Trials on Infertility
- Evaluation of Women With Endocrine and Reproductive-Related Conditions
This study was designed to allow inpatient and outpatient evaluation of women with a variety of reproductive and endocrine-related disorders for the purposes of research and physician education.
- Ovarian Follicle Function in Patients With Premature Ovarian Failure
No proven therapy to restore ovarian function and fertility is available to patients with karyotypically normal spontaneous premature ovarian failure. Half of these patients have primordial follicles remaining in the ovary, and these follicles can function intermittently. This is a diagnostic study that permits baseline clinical evaluation of patients with premature ovarian failure. The findings will determine patients' suitability for specifically focused therapeutic research protocols.
- Inherited Reproductive Disorders
During puberty, children begin to develop into adults. Problems with the hormones released during puberty can affect the reproductive system. Some people have low hormone levels that severely delay or prevent puberty. Others start puberty abnormally early. Some people may have a normal puberty but develop reproductive disorders later in life. This study aims to learn more about how these disorders may be inherited.
- Sperm Banking Among Adolescents Newly Diagnosed With Cancer: Development of a Profiling and Referral Tool
Despite the known adverse effects of specific cancer treatments on fertility, only 18% to 26% of at-risk adolescents and young men in the United States cryopreserve sperm prior to cancer treatment. The sperm banking rates are even lower among adolescents who have increased anxiety at cancer diagnosis, are lower in age and socioeconomic status, are of evangelical religious orientation, or are diagnosed with leukemia/lymphoma. This study examines risk factors associated with failure to bank sperm among adolescents with cancer, a developmentally distinct population ripe for intervention.
- Pregnancy in Polycystic Ovary Syndrome II Study
This trial is investigating the safety and efficacy of two treatments for PCOS-related infertility—an aromatase inhibitor (letrozole) compared to clomiphene citrate—for ovulation, conception, and live births in infertile women with PCOS. This study is nearing completion.
