VINCENT FELLOWS IN REPRODUCTIVE ENDOCRINOLOGY AND INFERTILITY


Solving Infertility

The goal of experts in Reproductive Endocrinology and Infertility is to turn patients into parents. The Vincent Department of OB/GYN has one of the highest success rates in helping couples have children including offering in-vitro fertilization (IVF) technologies for more than 25 years. During their research year, Vincent fellows are exploring ways to improve fertility for a wide range of patient conditions.

How Does Anti-Müllerian Hormone Affect the Pre-implantation Embryo? How Do Markers in Follicular Fluid Correlate with IVF Outcomes?

How Does Anti-Müllerian Hormone Affect the Pre-implantation Embryo? How Do Markers in Follicular Fluid Correlate with IVF Outcomes?

Evelyn Minis, MD, a Vincent fellow in Reproductive Endocrinology and Infertility, is focusing on two areas of in-vitro fertilization (IVF) research. One of her basic science projects is looking into anti-Müllerian hormone (AMH) signaling in the pre-implantation embryo. Previously it has been shown that AMH plays a crucial role in fetal development and sexual differentiation, however its role in the pre-implantation embryo has not been investigated. To investigate this question, she is culturing mouse embryos with AMH and without AMH, comparing gene expression between the two groups. In another research project, she is studying markers of ovarian stimulation in follicular fluid collected from patients at the time of oocyte retrieval. Specifically, she is looking into markers that differ between different phases in the mouse estrous cycle. She is investigating how these markers vary between patients with different infertility diagnoses and how they correlate with response to stimulation during IVF.

Are Different Genes Expressed in the Follicular Fluid of Patients with PCOS?

Are Different Genes Expressed in the Follicular Fluid of Patients with PCOS?

Hadi Ramadan, MD, a Vincent fellow in Reproductive Endocrinology and Infertility, is studying genetic markers found in follicular fluid of patients undergoing in-vitro fertilization (IVF). During IVF, patients are given medication to stimulate the ovary to produce oocytes (eggs), which are surrounded by follicular fluid. These oocytes then are retrieved and fertilized by sperm in the lab to produce an embryo. By comparing gene expression in the follicular fluid of IVF patients with polycystic ovarian syndrome (PCOS), a condition in which small cysts develop along the outer edge of the ovaries, with IVF patients who do not have PCOS, his research aims to explain why these populations respond differently to ovarian stimulation as well as have different metabolic profiles. This understanding may lead to improved IVF outcomes in both PCOS and non-PCOS patients.

What is the Role of Anti-Müllerian Hormone in Pre-implantation Embryo Development?

What is the Role of Anti-Müllerian Hormone in Pre-implantation Embryo Development?

Victoria S. Jiang, MD, a Vincent fellow in Reproductive Endocrinology and Infertility, is studying the role of anti-Müllerian hormone (AMH) in early pre-implantation embryo development. This protein, which is produced by the endometrium and the ovaries of reproductive-age women, plays key roles in fetal development and sexual differentiation. However, little is known about its role in embryo development. Dr. Jiang is studying the effects of AMH in mouse and human embryos, characterizing the expression and downstream gene changes associated with varying concentrations of exposure. These findings may lead to a better understanding of role of AMH in embryogenesis and ultimately to improving in-vitro culture environments.

How Does Anti-Müllerian Hormone Affect Human Granulosa Cells?

How Does Anti-Müllerian Hormone Affect Human Granulosa Cells?

Victoria Fitz, MD, MSCR, a Vincent fellow in Reproductive Endocrinology and Infertility, is studying a protein called anti-Müllerian hormone (AMH), which is produced by the ovaries of reproductive-age women and has been found to inhibit development of egg-containing follicles. This protein has potential applications in prevention of ovarian aging, protection of ovarian function from the effects of chemotherapy and optimization of in-vitro fertilization (IVF) cycles. The mechanism of AMH action has been characterized in a variety of animal models, but she is culturing granulosa cells obtained from follicles of IVF patients to understand changes in gene expression in human cells in response to AMH treatment. She also is studying the effect of novel medications that may act on the same pathway to produce a similar response in these cells. These findings may lead to a better understanding of the action of AMH in human cells and ultimately to developing new treatments for fertility preservation, contraception and adjuncts to IVF.
