1 RECOMBINANT VS. URINARY FSH IN IUI J. Serna MD PhD

2 QUESTIONS Is it necessary multiple follicle development for IUI? IUI vs. TI? Best medication?

3 QUESTIONS Is it necessary multiple follicle development for IUI? – –Balance risk/benefits – –Difficult to draw clear conclusions from studies in subfertile couples

4 PRs IN IUI EtiologyNon StimulatedClomiphenehMG Male Factor Unexplained Endometriosis Anovulation Cervical PR: Natural cycle:4.6% CC: 11.8% Gonadotropins17.7%

8 QUESTIONS Is it necessary multiple follicle development for IUI? IUI vs. TI? Best medication?

9 Metaanalysis: MFD + TI vs. MFD + IUI PR/cycle > double vs. NC and > 5 times FSH + IUI vs. NC OR 2.37 FSH + IUI Hughes E, Hum Reprod 1997; 12(9):

10 In most cases it is better MFD vs. natural cycle Gonadotropins are better than CC in most non-PCO patients TI yields worst results than IUI

11 QUESTIONS Is it necessary multiple follicle development for IUI? IUI vs. TI? Best medication?

12 Drugs for ovarian stimulation - Clomiphene citrate - Gonadotropins - hMG - FSH ( uFSH vs rFSH)

13 Gonadotropins Menotropin Urofollitropin – –Almost no LH rFSH – –Highest purity – –Batch to batch consistency – –Potentially allergenic urinary proteins

14 Urinary Highly Purified Human FSH (uhpFSH) Active FSH Immunoselection (anti-FSH Ab) Metrodin ® HP: 95 % purity LH activity 0,1 UI/mg FSH activity 9000 UI/mg < 5 % other proteins Less batch to batch variability Better control intersubject variability Lunenfeld B. Reprod Biomed Online 2002; 4 supp 1: 11-17

15 Evidence of urinary prion excretion in asymptomatics animals and humans Not able to develop the disease after CNS injection Shaked GM. J Biol Chem 2001; 276: Theoretical risks: Urinary products: infected donors Recombinant products: hamster cells, bovine serum Reichl H. Hum Reprod 2002; 17: Debate: Absence of data do not exclude the risk of CJD transmission. Matorras R. Hum Reprod 2002; 7: 1675 Main problem: price, activity Crosignani PG. Hum Reprod 2002; 7: There is no demonstrated infective reason to interrupt urinary products, nor absolute security with recombinant counterparts. Balen A. Hum Reprod 2002; 7: Prionic risk

17 AIM To compare the results of ovulation induction in couples undergoing IUI with uhpFSH vs. rFSH

19 Material and Methods Prospective Randomized June 1999 to May women 224 cycles

20 Inclusion criteria Infertility more than 1 year 18 and 38 y.o. At least one normal patent tube MSC > 5 Mill/mL after swim-up No previous OI, TI or IUI No PCOs Institutional review board approval + IC

21 Pretreatment work-up HSG and/or laparoscopy TVU scan D3 Serum FSH, LH, E2, PRL and TSH D22 Progesterone Semen analysis WHO + MSC

22 Diagnostic groups Endometriosis Ovulatory Dysfunction Male Factor Unexplained infertility

23 Distribution of etiologies Male Factor 39% Ovulatory dysfunction 20% Endometriosis 6% Unexplained infertility 35%

24 Stimulation Protocol TVUS on 1 st to 3 rd cycle day Ovulation induction started on D3 with – –rFSH 100 IU – –uFSH 150 IU Randomly assigned by even/odd file record number Patients with several cycles received the same medication

25 5000 UI hCG 100 UI rFSH 150 UI uFSH MENS rFSH uFSH TVS IA TVS

26 Stimulation Protocol TVUS Ovarian monitoring started on D5 No dose adjustment 5,000 IU hCG with a 18 mm leading follicle + E2 +12 & +36 h IUIs

27 Cancellations No ovarian response 5 or more follicles Luteal phase support 400 mg bid micronized vaginal progesterone Serum hCG 12 days after 2 nd IUI Clinical pregnancy defined as HB days after the positive result

28 Outcomes measures Main – –Total number of follicles > 12 mm Secondary – –Follicles >17mm and – –Number of cycles with 2- 4 follicles >17mm – –Duration of gonadotropin treatment – –Total FSH dose – –Serum E2 on hCG – –Ration E2/follicle > 17mm – –E2/units of FSH
