Introduction And Background
Cancer, a formidable adversary to health and well-being, often inflicts collateral damage on reproductive capabilities.The aggressive nature of cancer treatments, such as chemotherapy and radiation, significantly affects the reproductive organs, jeopardizing the fertility of both male and female patients.Understanding the intricate interplay between cancer and fertility is paramount to addressing the unique challenges faced by survivors [1].
For individuals facing a cancer diagnosis, the prospect of infertility adds a layer of emotional distress.Recognizing the profound impact on quality of life, fertility preservation has emerged as a crucial aspect of comprehensive cancer care.Preserving the ability to conceive post-treatment addresses patients' immediate concerns and contributes to their long-term psychological and emotional well-being [2].
In recent years, uterine transplantation (UTx) has emerged as a groundbreaking and innovative solution to the fertility challenges posed by cancer treatments.While conventional fertility preservation methods primarily focus on gamete preservation, UTx offers a unique avenue for individuals who have lost their uterus due to cancer or other medical conditions.This review delves into the landscape of UTx, exploring its evolution, applications, challenges, and the promise it holds for cancer survivors seeking to rebuild their reproductive futures [3].This comprehensive review aims to examine the landscape of UTx in the context of fertility preservation for cancer survivors.By synthesizing current research, successful cases, and ongoing challenges, this review seeks to provide a thorough understanding of the role UTx plays in offering hope to those whose fertility is compromised by cancer treatments.By exploring surgical techniques, post-transplant care, ethical considerations, and future directions, we aim to shed light on the potential of UTx as a transformative solution in reproductive medicine.Fertility preservation is an option for individuals facing a cancer diagnosis, and emerging research is providing clinicians with an increasing number of reproductive and hormonal management tools [8].

Review
Patients need to discuss the potential impact of cancer treatment on fertility with their healthcare team before starting treatment and to consider options like sperm banking or egg freezing to preserve fertility [10,11].Physicians play a crucial role in providing information about fertility preservation and reproductive options for cancer patients and survivors, and they need to understand the effects of specific cancer treatments on fertility [11].

Challenges Faced by Cancer Survivors in Preserving Fertility
Cancer survivors encounter a myriad of challenges when it comes to preserving their fertility.Time sensitivity poses a significant hurdle, as the urgency of cancer treatment often leaves little opportunity for comprehensive fertility planning.Financial constraints may limit access to fertility preservation methods, and the emotional toll of a cancer diagnosis can complicate decision-making regarding reproductive options.Moreover, the unpredictability of treatment outcomes and the potential for infertility-related distress contribute to the complexity of navigating fertility preservation for cancer survivors [10][11].

Existing Fertility Preservation Methods and Their Limitations
Existing fertility preservation methods include various options that can be applied based on a patient's age, ovarian involvement risk, available time, and cancer type.Some of the most reliable methods for premature and post-mature puberty are embryo cryopreservation and ovarian tissue cryopreservation, respectively.Other approaches, such as artificial ovary and isolation and cryopreservation of follicles, are still under investigation.These strategies combine recent advances in assisted reproductive technologies (ARTs), cryotechnologies, and novel cell culture systems [12].
Nonetheless, limitations persist, and certain methods remain in the experimental stage.For instance, ovarian transposition is classified as an experimental approach to fertility preservation [13].The utilization of fertility preservation methods in cancer patients remains relatively underexplored, hindering a more comprehensive understanding of their efficacy [14].Moreover, changes in legislation may impact the accessibility of specific fertility preservation options, with ovarian tissue cryopreservation currently standing as the sole available option for prepubertal patients [15].Although fertility preservation methods provide a range of patient options, constraints exist, prompting ongoing research efforts to enhance these techniques and broaden their accessibility.

Definition and Explanation of UTx
UTx is a surgical procedure that involves the transplantation of a uterus from a donor to a recipient, typically a woman who has either congenital absence of the uterus (Mayer-Rokitansky-Küster-Hauser syndrome) or has lost her uterus due to a medical condition such as cancer or hysterectomy.This intricate procedure aims to restore the recipient's reproductive anatomy, enabling her to conceive and carry a pregnancy to term [16].

Historical Background and Development of UTx
The history and development of UTx can be traced back to the early 20th century.Studies in rats, domestic species, and non-human primates validated and optimized the UTx procedure in terms of surgical aspects, immunosuppression, rejection diagnosis, and peculiarities of pregnancy in immunosuppressed patients [17].
The first reported uterine transplant was performed in Saudi Arabia in 2000 when a 26-year-old woman who had suffered postpartum hemorrhage after a Cesarean section underwent the procedure [18].The first live birth after UTx was reported in 2014 by a medical group in Sweden, involving a 35-year-old woman with a müllerian anomaly who gave birth to a premature baby [18].In the United States, the first UTx was performed in 2016 at the Cleveland Clinic, but the patient experienced complications and required the removal of the transplanted uterus [18].The first successful UTx in the United Kingdom took place in 2023 at the Churchill Hospital, Oxford, where doctors transplanted a uterus from a 40-year-old woman to her 34year-old sister, who had a rare condition affecting her ability to carry a child [18].Over the years, UTx has evolved as a potential treatment for absolute uterine factor infertility (AUFI), offering hope for women who are unable to conceive due to the absence or non-functionality of the uterus [18].However, the procedure is still in development, and more research is needed to improve success rates and reduce risks [17].

Key Medical and Ethical Considerations in UTx
UTx raises several key medical and ethical considerations.From a medical perspective, the risks for the recipient include surgery, immunosuppression, pregnancy, and delivery [19].Donors, recipients, partners, and unborn children must be considered in analyzing the ethical risks and benefits of UTx [19].Additionally, the choice between brain-dead donors and living donors, as well as the risks for living donors, are important medical and ethical considerations [19,20].Furthermore, the ethical and social value of gestation, the extension of UTx to transgender women or men, and the risks associated with immunosuppressive therapy and transplant surgery are also significant ethical considerations [21].
Ethical principles guiding other organ transplants may not directly apply to UTx, and there is general agreement on the importance of risk reduction and the sharing and maintenance of patient data on an international registry [21].It is also acknowledged that UTx should not be offered as part of routine clinical practice until safety and efficacy are proven and more data are required to fully understand the risks and benefits of the treatment [21].As UTx moves from the research phase to the clinical phase, it is crucial to review the ethical, legal, and social implications before widespread clinical practice [22].The UTx presents a range of medical and ethical considerations, including the risks for recipients and donors, the ethical and social value of gestation, and the need for comprehensive risk assessment and data collection before the procedure can be widely adopted [19][20][21][22].

Eligibility Criteria for Cancer Survivors Seeking UTx
UTx is a potential treatment for AUFI, including cases related to gynecological malignancies, offering hope for women who are unable to conceive due to the absence or non-functionality of the uterus [3,23].The eligibility criteria for UTx include being of childbearing age (20-40 years old), having no history of HIV or hepatitis B, and having no history of major uterine surgery [23].Additionally, potential donors must be premenopausal, have completed childbearing, have experienced successful pregnancy and live birth, and be genetically related to the transplant recipient [23].However, it's important to note that UTx is still an evolving field, and more research is needed to improve success rates and reduce risks [3].
For cancer survivors seeking UTx, eligibility criteria may vary depending on the type and stage of cancer, the treatment method, and the patient's age and overall health [3].Patients need to discuss the potential impact of cancer treatment on fertility with their healthcare team before starting treatment and to consider options like sperm banking or egg freezing to preserve fertility [3].Physicians play a crucial role in providing information about fertility preservation and reproductive options for cancer patients and survivors, and they need to understand the effects of specific cancer treatments on fertility [3].
