Hallo
Die 'Progesteron-Frage' (welches Mittel, wieviel, wie lange etc.) wird hier laufend diskutiert und es besteht eine grosse Unsicherheit, ob das (meist) empfohlene Utrogestan 200 mg (1-1-2) oder Crinone 8% genügen würde. Die Meinung dies genüge nicht, ist im Forum weit verbreitet, und so wird denn auch oft mit Progesteron-Spritzen ergänzt.
Mein eigener EZSP-Arzt befürwortet das zusätzliche Progesteron-Spritzen nicht und sagt, Utrogestan 200 mg (1-1-2) sei bereits hochdosiert und völlig ausreichend. Von wissenschaftlicher Seite her, sei die Frage bereits seit mehreren Jahren klar beantwortet und mehrfach repliziert worden.
Die vielen Studien ergaben keine erhöhten Geburtenraten bei einer hochdosierten Progesteron-Therapie!
Untenstehend sind einige wissenschaftliche Publikationen dazu aufgeführt. Solch kontrollierten wissenschaftlichen Studien kann man trauen, denn die Ergebnisse wurden mehrfach von unterschiedlichen Forschungsgruppen auf der ganzen Welt, in tausenden von IVF-Zyklen, repliziert.
Diese und viele anderen Studien sind zu finden unter: http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?DB=pubmed
Alles Gute wünscht Euch

Effect of progesterone supplementation in early pregnancy on the pregnancy outcome after in vitro fertilization
Publiziert in: Fertil Steril. 2006 May;85(5):1550-2. Epub 2006 Apr 17.

Abstract:
A retrospective cohort study was performed to evaluate IVF clinical pregnancy rates and livebirth rates between patients receiving progesterone supplementation through the first trimester of pregnancy (first trimester protocol) at 12 weeks vs. discontinuation after a positive beta-hCG test 2 weeks after retrieval (luteal protocol) at 4 weeks of pregnancy. A similar rate of clinical pregnancies occurred at 7 weeks (81.8% luteal protocol vs. 85.8% first trimester protocol; P=.49) and for livebirth rates (76.8% luteal protocol vs. 75.0% first trimester protocol; P=.80), but a trend toward a higher rate of pregnancy loss after 7 weeks in the first trimester protocol group occurred (15.5% vs. 4.4%; P=.06), indicating that first trimester progesterone supplementation may support early pregnancy through 7 weeks by delaying miscarriage but does not improve livebirth rates.

Abstract:
BACKGROUND: The aim was to study whether prolongation of luteal support during early pregnancy influences the delivery rate after IVF. METHODS: Dual centre study including 303 women who achieved pregnancy after IVF or ICSI was used. All were treated with the long protocol using GnRH agonists and given luteal support with 200 mg vaginal progesterone three times daily during 14 days from the day of transfer until the day of a positive HCG test. The study group (n = 150) withdrew vaginal progesterone from the day of positive HCG. The control group (n = 153) continued administration of vaginal progesterone during the next 3 weeks of pregnancy. RESULTS: The number of miscarriages prior to and after week 7 of gestation was seven (4.6%) and 15 (10.0%) in the study group and five (3.3%) and 13 (8.5%) in the control group respectively. The number of deliveries was 118 (78.7 %) in the study group and 126 (82.4 %) in the control group. The differences were not significant. CONCLUSIONS: Prolongation of progesterone supplementation in early pregnancy has no influence on the miscarriage rate, and thus no effect on the delivery rate. Progesterone supplementation can safely be withdrawn at the time of a positive HCG test.

Progesterone supplementation during early gestation after in vitro fertilization has no effect on the delivery rate.

OBJECTIVE: To compare the delivery rate with IVF or ICSI in women who did and did not receive progesterone supplementation in the first 3 weeks after a positive hCG test result. DESIGN: Retrospective study. SETTING: Fertility Clinic, Rigshospitalet University Hospital, Copenhagen, Denmark. PATIENT(S): 200 pregnant women who did not receive progesterone (intervention group) and 200 pregnant women who received progesterone for 3 weeks after a positive hCG result. INTERVENTION(S): In the study group, vaginal progesterone therapy was withdrawn on the day of positive hCG result. In the control group, treatment with progesterone, 600 mg/d, was continued for 3 weeks after a positive hCG result. Both groups received 600 mg of progesterone starting on the day of embryo replacement until testing positive for pregnancy 14 days after embryo transfer. MAIN OUTCOME MEASURES: Delivery rate. RESULT(S): The number of deliveries was 126 in the study group and 128 in the control group. CONCLUSION(S): The delivery rate was the same in pregnant women who received and those who did not receive progesterone for 3 weeks after a positive hCG result. Progesterone supplementation for more than 2 weeks after embryo transfer may therefore yield no benefit in terms of pregnancy.

Efficacy and tolerability of vaginal progesterone capsules (Utrogest 200) compared with progesterone gel (Crinone 8%) for luteal phase support during assisted reproduction.
Publiziet in: Fertil Steril. 2005 Jun;83(6):1641-9.

OBJECTIVE: To demonstrate the comparative efficacy and tolerability of capsules containing 200 mg of P (Utrogest 200) or Crinone 8% gel for luteal phase and early pregnancy support during assisted reproduction techniques (ART). DESIGN: Prospective, multicenter, randomized, controlled, open, parallel-group Phase III trial. SETTING: Seventeen German IVF centers. PATIENT(S): Four hundred thirty women who underwent their first IVF or intracytoplasmic sperm injection cycle were randomized after successful transfer of two or three embryos from July 1999 through September 2001. INTERVENTION(S): Patients vaginally applied capsules containing 200 mg of P (Utrogest 200) three times per day or containing Crinone 8% gel twice per day. Therapy was started in the evening of the ET day and continued up to 10 weeks in pregnant women. If the pregnancy test proved to be negative, application was stopped. MAIN OUTCOME MEASURE(S): Ongoing pregnancy rate at the end of the study (12th week of gestation). Secondary outcomes were rate of implantation and abortion, number and reasons of withdrawals, as well as adverse events, assessment of tolerability, and acceptance. RESULT(S): There were no relevant differences in demographic and other characteristics between the two groups. Ongoing pregnancy rates were 25.2% in the Utrogest 200 group and 22.2% in the Crinone 8% group when patients were analyzed who normally completed the trial. In the Utrogest 200 vs. the Crinone 8% group, the implantation rate (14.7% vs. 11.9%) and abortion rate (18.2% vs. 19.1%) were not statistically different. The rate of withdrawals at the individual visits also did not differ between treatment groups. Tolerability of both drugs was good, and very few study drug-related adverse events were observed in both groups. CONCLUSION(S): The luteal phase support in ART cycles with Utrogest 200 capsules (three times per day) or Crinone 8% gel (two times per day) by the vaginal route resulted in similar outcomes with respect to implantation, ongoing pregnancy, and abortion rates. The two recommended regimens of P supplementation in ART proved to be equivalent and safe.
