The purpose of this study is to analyze the effect of parity, menopause and reproductive lifespan on kidney structure and function.

The purpose of this study is to determine how cystatin C, creatinine, and microalbuminuira change with gender affirming hormone therapy initiation. Blood draws and urine testing will be done at time 0, 3 months, and 6 months of hormone therapy. The results will  determine how to best interpret lab values in transgender individuals receiving gender affirming hormone therapy.

The purpose of this study is to evaluate how advancing stages of chronic kidney disease (CKD) may impact the hypothalamic-pituitary-gonadal axis,and how alterations in sex hormones and menstrual cycles correlate with changes in endothelial health and sexual function before and after transplant.

The primary purpose of this study is to identify women with Primary Hyperoxaluria (PH) who have had pregnancies from a large, international registry and describe the maternal and fetal complications of pregnancies in this cohort, as well as compare outcomes of pregnancies before and after organ transplantation in women with PH.

The purpose of this study is to test the hypothesis that pregnancy post-transplant will increase the risk of adverse renal events (defined as acute rejection, reduction in GFR by 30%, new or worsening proteinuria, or graft-loss).  The risk will be increased in women with complications in pregnancy, such as preeclampsia or pre-term delivery.
