Cumulative pregnancy rates for in vitro fertilization
Fertility and Sterility, 1986Data on 575 couples undergoing 1057 consecutive cycles of in vitro fertilization (IVF) were used to calculate cumulative pregnancy rates for repeated IVF cycles. Excluding preclinical abortions and couples in whom the male partner had poor semen parameters, calculated cumulative pregnancy rates for cycles 1 to 6 were 13.6%, 24.8%, 37.2%, 47.8%, 52.2 ...

Pregnancy rates after laparoscopy for infertility
European Journal of Obstetrics & Gynecology and Reproductive Biology, 1984To obtain prognostic data on the likelihood of pregnancy in infertile women with no observable abnormalities at diagnostic laparoscopy, the occurrence of pregnancy was studied in a series of 229 patients. The cumulative conception rate during a follow-up period of at most 5 yr was 50%.

BMJ, 2014It seems heartening that unplanned conception and pregnancy rates in teenagers are decreasing in England,1 New Zealand,2 and the United States.3 However, we should be cautious in thinking that our social programmes and availability of new family planning technologies are the only solutions to this problem.

Age and pregnancy rates in in vitro fertilization
Journal of In Vitro Fertilization and Embryo Transfer, 1991The influence of women's age on the results of in vitro fertilization (IVF) was analyzed in 1801 women undergoing the procedure. Advancing age was found to be related to significant reduced success rates from an average of 30.1% per transfer below the age of 36 years to 15.9% per transfer at 37 years or more (P less than 0.001).

Pregnancy Rates after Testicular Torsion
Journal of Urology, 2016To our knowledge the effect of testicular torsion on the pregnancy rate is unknown. In this study we focused on the pregnancy rate, which is the ultimate index of fertility status.We reviewed the records of 273 patients who presented to our emergency room with testicular torsion between 1994 and 2014.
