INTRODUCTION: To report the progress of the human living uterus transplant research project in Singapore. MATERIAL AND METHODS: The uterus transplant research project began in 2012 with a collaboration between the Swedish and Singapore tea…

PURPOSE: Human papillomavirus (HPV), the most common sexually transmitted infection, has been proposed as a potential factor in male infertility. This study aimed to assess the prevalence of HPV in semen samples from men undergoing in vitro…

Leukocytes are in situ regulators critical for ovarian function. However, little is known about leukocyte subpopulations and their interaction with follicular cells in ovulatory follicles, especially in humans. Single-cell RNA sequencing (s…

Hysterectomy, most often performed because of bleeding disorders or uterine leiomyoma, is one of the most common major surgical procedures in women and is usually performed during the perimenopausal period on ages 45-55 years. Hysterectomy …

BACKGROUND: To provide the optimal milieu for implantation and fetal development, the female reproductive system must orchestrate uterine dynamics with the appropriate hormones produced by the ovaries. Mature oocytes may be fertilized in th…

INTRODUCTION: The first live birth after uterus transplantation occurred in Sweden in 2014. Uterus transplantation has repeatedly, and at many centers worldwide, proven to be a feasible treatment for absolute uterine factor infertility. Hys…

OBJECTIVE: To evaluate uterine arteries (UA) of potential living donors for uterus transplantation (UTx) by comparison of CT angiography (CTA), digital subtraction angiography (DSA), and MR angiography (MRA) with care taken to minimize radi…

BACKGROUND: Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, also referred to as Müllerian aplasia, is a congenital disorder characterized by aplasia of the uterus and upper part of the vagina in females with normal secondary sex characteris…

PURPOSE: Allogeneic ovarian transplantation may be an alternative in the future to oocyte donation in women with premature ovarian failure. The objectives of this study were to (a) evaluate allotransplantation feasibility for restoration of…

Uterus transplantation is today the only available treatment for absolute uterine factor infertility which is caused by either congenital/surgical uterine absence or that a present uterus is non-functioning. Structured animal-based research…

Absolute uterine factor infertility (AUFI) has traditionally been regarded as untreatable. Gestational surrogacy (GS) is not permitted in most countries and societies in the world due to ethical, religious or legal reasons. The interest in …

BACKGROUND: We aimed to investigate the use of ovarian cyst fluid as a source for biomarker discovery and to find novel biomarkers for use in the diagnosis of epithelial ovarian tumors. RESULTS: Ovarian cyst fluids from 218 women were coll…

The matrix metalloproteinases (MMPs) are postulated to facilitate ovulation by remodeling the follicular wall. The MMP family is comprised of 25 different proteinases, many of which share common structural and functional characteristics and…

17β-estradiol, acting through estrogen receptors α and β, plays a fundamental role in the regulation of Fallopian tube cell homeostasis and in the modulation of normal tubal physiological processes. Fluctuations in E2 levels also play cruci…

CONTEXT: Tissue-specific dicer1 knockout mice display severe, irreversible Fallopian tube damage and disrupted tubal transport. It is not known how Dicer1 affects human Fallopian tube function. OBJECTIVE: The aim of the study was to invest…

AIM: Ovulation is a local physiological inflammatory process with active participation of inflammatory mediators and immune cells. To prevent extensive inflammatory injury to the follicle at ovulation there is also a local anti-inflammatory…

Background. Retrospective studies have indicated differences in sexuality and general psychological well-being between women who have undergone hysterectomy only and those undergoing hysterectomy and oophorectomy. These differences may be t…

OBJECTIVE: To determine whether oophorectomy during the perimenopause, with the associated decline in ovarian androgens, affects sexual function and psychological well-being negatively. DESIGN: Prospective, observational study comparing se…

BACKGROUND: Nitric oxide is a potent vasodilator and is involved in several physiological events during the female reproductive cycle. OBJECTIVE: The aim of this study was to determine the acute effects of a nitric oxide donor on ultrasoun…

Luteinizing hormone (LH) stimulates prostaglandin biosynthesis and steroidogenesis in preovulatory (PO) follicles prior to ovulation. Since the ovulatory process shares many similarities with an inflammatory reaction, mediators of the infla…
