conventional infertility treatment vs. fast track to ivf

Conditions: Infertility

Summary: the purpose of this randomized prospective clinical trial is to determine whether an infertility treatment that moves quickly to in vitro fertilization (ivf) is more cost effective than the usual treatment strategy which includes various combinations of infertility drugs and intrauterine insemination (iui) prior to utilizing in vitro fertilization.

this is a randomized clinical trial to evaluate the efficacy, adverse events, and particularly cost and cost-effectiveness of two alternative infertility treatment strategies for patients who would otherwise be candidates for ovulation induction and iui as their initial treatment. the two therapies compared are conventional treatment and fast track to ivf. conventional therapy is a cost-conscious progressive treatment strategy that begins with the least invasive form of ovulation induction, clomiphene/iui. it then progresses to fsh/iui and, if pregnancy is not achieved, to ivf. the fast track to ivf strategy begins with clomiphene/iui; if pregnancy does not result, these patients bypass fsh/iui and move directly to ivf. we hypothesize that the fast track to ivf therapy results in a higher pregnancy rate, lower rates of medical complications during treatment, lower rates of pregnancy complications, and costs no more than conventional infertility treatment. the trial has the following specific aims: aim 1: to compare the number of deliveries per initiated cycle, the proportion of women with a clinically recognized intrauterine pregnancy, and the time to clinical pregnancy between fast track to ivf and the conventional treatment arms of the clinical trial. aim 2: to compare the frequency of infertility treatment complications between the fast track to ivf arm and the conventional treatment arm. aim 3: to compare the occurrence of pregnancy complications between the fast track to ivf arm and the conventional treatment arm. aim 4: to evaluate the costs and cost effectiveness of the two alternative treatment strategies by comparing the direct and indirect medical costs between the fast track to ivf and conventional treatment arms of the clinical trial. this is a collaborative study between boston ivf, harvard vanguard medical associates, harvard school of public health, blue cross blue shield of massachusetts, harvard pilgrim health care, and tufts health plan. total enrollment: 503 couples

Eligibility criteria:
inclusion criteria: * female partner age 21 up to 40th birthday, at the time of recruitment. infertility is defined as failure to conceive a recognized pregnancy after one year (or 12 menstrual cycles) of unprotected intercourse. * male partner has a normal semen analysis with a sperm concentration of \>15 million total motile sperm, \>1% normal forms by strict criteria, or \>5 million total motile sperm on iui prep. * female patient has at least one ovary and at least one ipsilateral patent fallopian tube confirmed by hsg or laparoscopy; pelvic pathology amenable to operative laparoscopy (pelvis restored to functional). the open tube cannot have had a previous ectopic (tubal) pregnancy and the closed tube cannot be a hydrosalpinx (a tube that is blocked at the end and filled with fluid), unless a tubal ligation has been performed at the junction of the uterus and fallopian tube. * patients with surgically corrected stages i and ii endometriosis will be included. * normal uterine cavity demonstrated by hsg, sonohysterogram (shg), or hysteroscopy; pathologies of uterine cavity amenable to operative hysteroscopy (cavity restored to normal and demonstrated by post operative study). * anovulatory patients who did not conceive after a minimum of three ovulatory cycles with any medications, not including gonadotropin therapy. anovulatory patients unable to achieve ovulation at dosages up to 150 mg of clomiphene or standard dosages of other ovulation inducing medications (i.e. bromocriptine). hypoestrogenic hypothalamic amenorrhea patients will qualify immediately for inclusion, prior to any gonadotropin therapy. * normal ovarian reserve demonstrated in all patients i.e., cycle day 3 fsh/e2 values of \<15 miu/ml and \<100 pg/ml, respectively. normal tsh and prolactin. * female body mass index ≤ 38. exclusion criteria: * previous tubal reconstructive surgery in which the pelvis was not restored to functional. * unilateral or bilateral hydrosalpinx (a tube that is blocked at the end and filled with fluid) that has not had a tubal ligation performed at the junction of the uterus and fallopian tubes. * a laparoscopy that demonstrated pelvic adhesions or endometriosis for which the pelvis could not be restored to normal by surgery or endometriosis was not ablated or excised. all patients with stages iii and iv endometriosis. * one or more prior ectopic pregnancies in which one or both tubes were rendered nonfunctional; two or more ectopic pregnancies, even if tubes are patent. * severe male factor (i.e.; semen analysis with a sperm concentration of \<15 million total motile sperm, \<1% normal forms by strict criteria, or \<5 million total motile sperm on iui prep). couples using donor semen will be excluded. * previous treatment with iui or ivf. previous treatment of normal ovulation patients with gonadotropins. * inadequate ovarian reserve demonstrating fsh \>15 miu/ml or estradiol \> 100 pg/ml. * patients requiring gamete intrafallopian tube transfer (gift), zygote intrafallopian tube transfer (zift), or tubal embryo transfer (tet). * female body mass index \> 38.
