*Okay, after posting my answer, I saw someone else had answered this, but as a "comment", so it was still listed as "unanswered"... sorry for the same results; I deleted the quotes from abstracts because of this, but I can still send you my search strategy on PubMed if you'd like!
By doing a search in PubMed, I found a review from the Netherlands specifically discussing cardiovascular disease and osteoporosis.
The citation is:
Gooren, L., Giltay, E., Bunck, M. (2008). Long-term treatment of transsexuals with cross-sex hormones: extensive personal experience. Journal of Endrocrinol Metabolism 93(1). Retrieved May 1, 2008, from PubMed database.
I also found a clinical trial, with the citation:
Mueller, A., Kiesewetter, F., Binder, H., Beckmann, M., Dittrich, R. (2007). Long-term administration of testosterone undecanoate every 3 months for testosterone supplementation in female-to-male transsexuals. Journal of Clinical Endocrinol Metabolism 92(9). Retrieved May 1, 2008, from PubMed Database.
I would be more than happy to send you my search strategy and subsequent results if you would like, and if you have access to PubMed. Just so far from glancing, there are probably at least 20 results that would be suited to what you're looking for.
