ÜYTE yönetmeliği
MADDE 18 –(8) İstenmeyen durum olan, anne ve çocuk sağlığını riske eden çoğul gebeliklerin önlenmesi esastır. Bu kapsamda;
a) ÜYTE yöntemlerinden biri olan klasik ovulasyon indiksiyonu ile 2 (iki) den fazla folikül gelişmemesi hedeflenmelidir. Çoğul gebeliklerin önlenmesi için üç veya daha fazla folikül gelişmesi halinde artifisyel inseminasyon işlemi yapılması yasaktır.

Advantages of oral drugs
• Low incidence of multiple pregnancies
• Low incidence of OHSS
• Low cost
• Less need for cycle monitoring
• More comfortable

CC
• Competitive antagonist of ovarian estrogen
• Requires an intact hypothalamic-pituitary-ovarian axis and
serum estradiol > 50 pg/ml.
• Endometrial thickness is initially decreased, but is later
increased compared to natural cycles as rising estrogen
concentration overcomes the antiestrogen effect. [Randall
JM, F&S, 1991]

Letrazol
• Third generation aromatase inhibitor
• Act directly to the ovary to decrease production of
estrogen
• Intraovarian androgens accumulate mid sized follicles
become atretic
• Multiple follicular ovulation are reduced compared to CC
• Used «off label»

CC for unexplained subfertility in women
ObjectivesClomiphene citrate in improving pregnancy outcomes in women with unexplained subfertility, dose range of 50 to 250 mg for up to 10 days. The primary outcome was live births.Selection criteriaOnly randomised controlled trials were included. Data collection and analysisSeven trials were included in this review.

CC for unexplained subfertility in women
Main results1159 participants from seven trials were collated. There was no evidence that CC was more effective than no treatment or placebo for live birth (odds ratio (OR) 0.79, 95% CI 0.45 to 1.38; P = 0.41) or for clinical pregnancy per woman with intrauterine insemination (IUI) (OR 2.40, 95% CI 0.70 to 8.19; P = 0.16).Authors' conclusionsThere is no evidence of clinical benefit of clomiphene citrate for unexplained fertility. .

Letrazol vs CC• A meta-analysis of four published randomized controlled
trials for ovulation induction in a total 662 patients with PCOS now provides strong evidence that letrozole is at least as effective as CC, the present gold standard, for ovulation induction with similar pregnancy rates ([RR] 1.02; 95% CI 0.83, 1.26).
• Letrazole is equally effective in inducing ovulation, but without antiestrogenic adverse effects, as a first-line therapy.

Letrazol vs CC• 5 fertility centers in Canada.• 911 newborns from women who conceived following CC or
letrozole treatment.• Congenital malformations and chromosomal
abnormalities in the letrozole group 2.4% and in the CC group 4.8%.
• The major malformation rate in the letrozole group was 1.2% and in the CC group was 3.0%.

Conclusion• IUI is the first choise particularly in male subfertility and
unexplained infertility• Letrazol is as effective and safe as CC. Absence of
antiöstrogenic effect of Letrazol is an advantage• Adding of oral drugs to gonadotropins reduce the cost of
the therapy but the pregnancy rate is not differ• In a subgroup of patients whose basal E2 < 30 pg/ml is
gonadotropins preferable• Adding GnRH antagonist to a gonadotropin stimulation
bevor IUI increase the pregnancy rates• Due to new regulation of ministery of health oral
drugs are more cost effective than the gonadotropins
