How frequently do miscarriages occur?

Women with the polycystic ovary syndrome do not respond well to treatment with luteinising hormone releasing hormone. To determine whether this might be due to an underlying endocrine disturbance basal concentrations of luteinising hormone were measured in 54 infertile women treated with pulsatile luteinising hormone releasing hormone and concentrations at the time of maximum follicular growth were measured in 23 of the patients. Forty one patients ovulated. Forty one patients ovulated and 27 conceived, but nine pregnancies terminated within four weeks after ovulation. Basal luteinising hormone concentrations were significantly lower in those who conceived (12.4 (range 1.3-29.0) IU/l) than in those who did not (19.0 (3.5-50.0) IU/l) and in those whose pregnancy progressed (9.6 (1.3-29.0) IU/l) than in those with early loss of pregnancy (17.9 (7.0-29.0) IU/l). Concentrations at the time of maximum follicular growth were significantly lower in women who ovulated (9.4 (2.9-35.4) IU/l) than in those who did not (29.0 (7.0-50.0) IU/l) and in those who conceived (6.2 (2.9-8.5) IU/l) than in those who did not (17.9 (4.0-50.0) IU/l). These results indicate that high concentrations of luteinising hormone during the follicular phase in women with polycystic ovaries have a deleterious effect on rates of conception and may be a causal factor in early pregnancy loss.
