Q1. Dr Tian:Dr Schindler,on behalf of chinese ob/gyn doctors, we would like to welcome you to beijing and give us a lecture this afternoon. I want to know how many times have you been to china? Dr Schindler:If this is the visit here, it is the third time. Dr Tian: Oh, really? Dr Schinlder: Yes.
Q2. Dr Tian: So, what's the impression about the changes of china and the impression about chinese ob/gyn? Dr Schindler: I can look at the time spent 1981 until now, and I think there is a dramatic change for that. Particular for the whole country, with the development and with the outlook, in particular of in beijing here in 2008 with the Olympic Games. I think there's dramatic development.
Q3. Dr Tian: Ok, thank you. And is there any academic exchange between Germany and China now? Dr Schindler:I think not only now, it already been the past. And my first visit was associated with an exchange program which was supported by the Chinese goverment as well as by the German goverment. In particular through our medical school at Essen.
Q4. Dr Tian: I see, OK. Great. What's your topic today? Dr Schindler:We want to talk today about menstrual disorder, in particular about the use of dydrogesterone, Duphaston. Dr Tian: You know the dysfunctional bleeding is a big problem in china now。 Dr Schindler:I don't know that. Dr Tian: It's a big probelm, especially for the rural areas, but doctors don't know how to use the drugs especially the hormones, progesterone and estrogen. So I think may be this afternoon's lecture will give us great help. Dr Schindler:I hope so.
Q5. Dr Tian: You know we have several types of progesterones. What's your opinion about dydrogesterone,Duphaston in luteal support compared with other progestins especially the microprogesterone? Dr Schindler:First of all, we have to differentiate. When you say luteal phase, you would have to ask me what women. Is the women who is concerned to get pregnant or is pregnant. Or is the women who just like adolescents or premenopausal women who has menstrual bleeding disturbance, or has a corpus luteal insuffeciency, by this having cycle disturbance. These are two different things. If we look at the first part, maybe the women want to get pregnant, the cycle is stimulated. You support the corpus luteum, then you can only use progestines who are not androgenic who are not anti-androgenic, because that androgenic one will jeopardise the female fetus and anti-androgenic one as the male fetus. So dydrogesterone and microprogesterone, as you mentioned, for this part, there are only these two. And of course there is the third one. It is the depo preparation. 17α-hydroxyprogesterone. But this you can not use in luteum fasion. Can you use something like that for the long term treatment for instance pregnancy. So actually for your question, luteal support, concern going want to get pregnant or finally being pregnant. Only two preparations, dydrogesterone as duphaston and micropregesterone. of course, Dydrogesterone compare with oral icropresgesterone, there are some unique advangtages, which will be introdcued in my lecture today. Dr Schindler:Now we get to the others, the other would be the young lady who has not fully develop the cycle, who have PCO, for instance, who has anovulation, or who has corpus luteum insufficiency, then either one. Of course you can use whole array of compound of progestogens. And you can use also progestins in some particular fact like a women who has acne, which might be a problem in china. Dr Tian: Still be a big problem for chinese women. Dr Schindler:I know. I know. I visited. I walked around in marvellous park in beijing and I am looking at the students, the women, I know the acne is the problem. So that's why I mentioned in particular that would be particular group of progestins. This particular group we call anti-androgenic progestins. There we have actually 4, I would say. One is cyproterone acetate. the second one is chlormadinone, the third is dienogest, and the fourth is drospirenone. So there are four anti-androgenic progestins. Away from this special indication. You can use the other progesterone, 19-nortestosterone as well, if you don't have a problem with acne. And you can give it in the second half part of the cycle to support similar to the normal cycle.
Q6. Dr Tian: So you have talked lot about the differnces of progesterone. What are the major consideration when you select progesterone. Dr Schindler:First of all, as I said already before. If we have any way on the reproduction or in getting pregnant, it would be only these two-dydrogesterone and micropregesterone. If she has androgenic effect, that means acne, for instance, then it would be the anti-androgenic progeterones. If she has no problem whatever, then you can use 19-nortestosterone as well. Dr Tian: Great. I think you will give us an excellent lecture this afternoon. Dr Schindler: I hope so. Dr Tian: Thank you very much. Dr Schindler: Thank you.
