“…Data from five separate prospective, open-label trials in which ovarian follicular growth was evaluated during natural menstrual cycles (34), ovarian stimulation cycles (52,53), and OC cycles (36,39) were evaluated in this study. The research protocols for each of the five studies were individually approved by the Biomedical Research Ethics Board at the University of Saskatchewan.…”

“…Minor waves are those in which selection of a dominant follicle does not occur; therefore, all follicles in minor waves undergo atresia (34). High-resolution transvaginal ultrasonography has also been used to document follicular development in women using hormonal contraception (36)(37)(38)(39)(40) or ovarian stimulation therapy for assisted reproduction (41,42).…”

“…It is also not known whether follicles that develop during OC use or as a result of exogenous gonadotropin stimulation differ physiologically from those that develop spontaneously. Some follicles that develop during OC use and ovarian stimulation ovulate, whereas others do not (36,39,52). The reasons for ovulatory failure, however, are poorly understood.…”

“…Scientific evidence suggests that some methods, including oral contraceptives, emergency contraception (EC), intrauterine devices and even lactational-amenorrhea method, can exhibit several effects in addition to preventing ovulation, such as biochemical or structural changes in the endometrium or alterations of fallopian tube [8][9][10][11][12][13][14][15]. These effects may sometimes prevent implantation (a postfertilization effect) and could be in conflict with some women's beliefs or value systems [16][17][18][19].…”

Objective: Some methods of family planning may occasionally work after fertilization or implantation. These effects may be important to some women. We explored Spanish women's attitudes towards these potential mechanisms of action of family planning methods.Study design: Cross-sectional study in a Spanish representative sample of 848 potentially fertile women, aged 18-49. Data were collected using a 30-item questionnaire about family planning. Logistic regression was used to identify variables associated with women's attitudes towards postfertilization effects.Results: The majority of women were married, held an academic degree and had at least one child. Forty-five percent of women would not consider using a method that may work after fertilization and 57% would not consider using one that may work after implantation. Fortyeight percent of the sample would stop using a method if they learned that it sometimes works after fertilization, increasing to 63% when referring to a method that sometimes works after implantation. Women who believe that human life begins at fertilization, those who believe it is important to distinguish between spontaneous and induced embryo losses and women who report having a religion were less likely to consider the use of a method with some postfertilization effects. Conclusion:The possibility of postfertilization effects may influence Spanish women's choice of a FP method. Information about mechanisms of action of birth control methods should be disclosed to women so that they can make informed choices.

“…Ovarian follicular development is not completely suppressed during OC use. Ovulatory and anovulatory follicles have been reported in women taking OC (10 -37), and endogenous E 2 levels reportedly attain preovulatory levels (10,15,16,26,31,38,39). The incidence of follicular activity during OC use depends on the type and dose of steroid hormones used in the formulation.…”
