Primary Outcome Measures:
  • The relative risks of genetic abnormalities identified at birth and within the first 60 days of life [ Time Frame: 2009 - 2016 ] [ Designated as safety issue: Yes ]
  • The relative risk of structural anomalies [ Time Frame: 2009 - 2016 ] [ Designated as safety issue: Yes ]
  • The relative risk of cognitive differences [ Time Frame: 2009 - 2016 ] [ Designated as safety issue: Yes ]
  • The relative risk of perceived differences of neuro-developmental milestones [ Time Frame: 2009 - 2016 ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • The rate of pregnancy complications, including pregnancy loss [ Time Frame: 2009 - 2016 ] [ Designated as safety issue: Yes ]
  • Rates of neonatal and infant medical disorders [ Time Frame: 2009 - 2016 ] [ Designated as safety issue: Yes ]
  • Rates of infant growth related to use of letrozole for stimulation of ovulation compared to other treatment modalities for ovulation stimulation, including compared to women who conceive spontaneously. [ Time Frame: 2009 - 2016 ] [ Designated as safety issue: Yes ]

Biospecimen Retention:   Samples With DNA

Mothers of newborn infants will be asked to consent to the collection of buccal cells from their infants for DNA testing. Fathers will also be asked to provide buccal cells via buccal swab smears, if blood has not been obtained from them in the course of an RMN trial. The DNA specimens will be available for use in other vetted studies to enable study of independent genetic and environmental factors and gene-environment interactions for a broad range of birth defects and infertility.

Estimated Enrollment: 1650
Study Start Date: May 2009
Estimated Study Completion Date: May 2017
Estimated Primary Completion Date: May 2016 (Final data collection date for primary outcome measure)
Infertile women who conceive spontaneously
Infertile women who conceive on various ovulation stimulation medications

Detailed Description:

This will be an observational cohort trial of the pregnancy of women who conceive in RMN trials, and of their resulting infants through the first 3 years of life.

Study specific procedures will include a patient completed log of prescribed and over the counter medications taken during a normal pregnancy, a review of their pregnancy, delivery, and neonatal records, an exam of the infant within 60 days of birth by a dysmorphologist, and yearly review of infant medical records, growth charts, and a yearly parent administered developmental questionnaire (Ages and Stages) for the first three years of the infant's life.


Ages Eligible for Study:   18 Years to 40 Years
Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

The population will include women with infertility who receive ovulation stimulation drugs within the context of a Reproductive Medicine Network sponsored trial as well as their infants.


Inclusion Criteria:

  • Positive serum hCG within the context of a RMN trial;
  • History of infertility meeting female subject entry criteria for a RMN trial;
  • Informed consent.

Exclusion Criteria:

  • Unable to comply with the demands of the trial.
