title: The effects of spontaneous luteinizing hormone surges on superovulatory cycles.
abstract: OBJECTIVE
  To determine the effect of a spontaneous luteinizing hormone (LH) surge on the cycle fecundity during superovulation induction.
  
  
  METHODS
  Superovulatory cycles of patients with various diagnoses are retrospectively compared.
  
  
  METHODS
  Reproductive Endocrinology Outpatient Clinic.
  
  
  METHODS
  A total of 1,185 superovulatory cycles from July 1, 1982 until November 1, 1991 are compared.
  
  
  METHODS
  The probability of achieving a pregnancy per treatment cycle.
  
  
  RESULTS
  Patients with unexplained infertility and hyperprolactinemia were more likely to have a spontaneous LH surge during superovulation than patients with either endometriosis or polycystic ovarian disease. However, the cycle fecundity rate did not differ whether or not an LH surge occurred, regardless of the diagnosis.
  
  
  CONCLUSIONS
  Spontaneous onset of an LH surge during superovulation induction does not influence the chances for pregnancy.
