Uterus Transplantation as a Therapy Method in Mayer-Rokitansky-Küster-Hauser Syndrome

Uterine Transplantation and Fertility Preservation: A Hopeful Horizon for Cancer Survivors

Uterine transplantation, a groundbreaking medical intervention, stands as a beacon of hope for cancer survivors grappling with the dual challenges of a cancer diagnosis and potential fertility loss due to aggressive treatments. This review provides a comprehensive exploration of uterine transplantation as an innovative solution for fertility preservation in the context of cancer survivorship. The multifaceted discussion encompasses the impact of cancer on fertility, the imperative of fertility preservation, and the evolution of uterine transplantation as a transformative procedure. The post-transplantation care section delves into the intricacies of recovery, the delicate balance of immunosuppressive therapy, and the ongoing support required for recipients to embrace the full spectrum of reproductive possibilities and overall well-being. Ethical considerations surrounding uterine transplantation, including donor selection, risk assessment, and societal perspectives, are critically examined to navigate the ethical landscape of this evolving field. In conclusion, uterine transplantation is presented as a medical breakthrough and a symbol of interdisciplinary collaboration, resilience, and unwavering hope. The review underscores the role of collaborative efforts among medical professionals, researchers, ethicists, and psychologists in advancing this transformative field. Looking to the future, uterine transplantation signifies a paradigm shift in fertility preservation, offering a tangible path toward parenthood for cancer survivors. The procedure, grounded in science, ethics, and compassion, illuminates the way forward, inspiring a future where fertility preservation becomes an attainable reality for those whose reproductive dreams were once compromised by cancer treatments.

Disorders of Sex Development: Classification, Review, and Impact on Fertility

In this review, the elements included in both sex determination and sex differentiation are briefly analyzed, exposing the pathophysiological and clinical classification of disorders or anomalies of sex development. Anomalies in sex determination without sex ambiguity include gonadal dysgenesis, polysomies, male XX, and Klinefelter syndrome (dysgenesis and polysomies with a female phenotype; and sex reversal and Klinefelter with a male phenotype). Other infertility situations could also be included here as minor degrees of dysgenesis. Anomalies in sex determination with sex ambiguity should (usually) include testicular dysgenesis and ovotesticular disorders. Among the anomalies in sex differentiation, we include: (1) males with androgen deficiency (MAD) that correspond to those individuals whose karyotype and gonads are male (XY and testes), but the phenotype can be female due to different hormonal abnormalities. (2) females with androgen excess (FAE); these patients have ovaries and a 46,XX karyotype, but present varying degrees of external genital virilization as a result of an enzyme abnormality that affects adrenal steroid biosynthesis and leads to congenital adrenal hyperplasia; less frequently, this can be caused by iatrogenia or tumors. (3) Kallman syndrome. All of these anomalies are reviewed and analyzed herein, as well as related fertility problems.

Disorders of Sex Development-Novel Regulators, Impacts on Fertility, and Options for Fertility Preservation

Disorders (or differences) of sex development (DSD) are a heterogeneous group of congenital conditions with variations in chromosomal, gonadal, or anatomical sex. Impaired gonadal development is central to the pathogenesis of the majority of DSDs and therefore a clear understanding of gonadal development is essential to comprehend the impacts of these disorders on the individual, including impacts on future fertility. Gonadal development was traditionally considered to involve a primary 'male' pathway leading to testicular development as a result of expression of a small number of key testis-determining genes. However, it is increasingly recognized that there are several gene networks involved in the development of the bipotential gonad towards either a testicular or ovarian fate. This includes genes that act antagonistically to regulate gonadal development. This review will highlight some of the novel regulators of gonadal development and how the identification of these has enhanced understanding of gonadal development and the pathogenesis of DSD. We will also describe the impact of DSDs on fertility and options for fertility preservation in this context.
