Amenorrhea is the medical term for the lack of menstrual periods, including on a permanent or temporary basis.

Phase N/A

The Genetic Investigation of Reproductive Disorders (Including Kallmann Syndrome)

The World Health Organization estimates approximately 10% of couples experience some sort of infertility problem. In humans, puberty is the process through which we develop reproductive capacity. Disorders of puberty have provided insight into the biology of reproduction and genetic technologies have enabled us to deepen understanding in this field. ...

Phase N/A

Ultrasound Characterization of Ovarian Follicle Dynamics in Women With Amenorrhea

In the ovaries, eggs rest in fluid filled sacs called follicles. When follicles grow they form small fluid-filled cysts that can be easily seen when we use ultrasound to view the ovaries. In women with regular menstrual cycles, groups of 10 to 20 follicles grow and regress at 2 or ...

Phase N/A

Use of PRP in Endometrial Reconstruction

The objective is to know the effect of these regenerative factors obtained from Platelet-Rich Plasma in an immunodeficient murine model with AS/EA Blood from patients with Asherman's Syndrome (AS) and Endometrial Atrophy (EA) will be collected, maintained under anticoagulant solution and after several centrifugations PRP will be obtained. Demonstration of ...

Phase N/A

Pheno- & Genotyping POF (WHO III)

First goal of the study is to phenotype patiens with hypergonadotropic ovarian dysfunction (WHO III) adequately. This group includes women with premature ovarian failure (POF), incipient ovarian failure (IOF), poor response after ovarian hyperstimulation, early menopause and hypergonadotropic primary amenorrhea. The standardized phenotyping consists of a questionnaire focusing on reproductive, ...

Phase N/A

The Cycle Disturbances OLigomenorrhea and Amenorrhea (COLA) Study & Biobank

Population Women with cycle disturbances are referred to the outpatient clinic specialized in cycle disturbances by 1st or 2nd line care providers for further diagnostic procedures. Inclusion criteria WHO I Hypogonadotropic hypoestrogenic status (previously: "hypothalamic amenorrhea") Low to normal serum follicle-stimulating hormone (FSH) concentrations Low serum estradiol concentrations WHO II ...

Phase N/A

Hormonal Regulation of Puberty and Fertility

The key initiating factors for reproductive development remain among the great mysteries of pediatric and reproductive endocrinology. The onset of puberty is initiated by pulsatile secretion of gonadotropin-releasing hormone (GnRH) from the hypothalamus. GnRH secretion is fully active during the neonatal period, quiescent throughout most of childhood, and is reactivated ...

Phase N/A

Baselines in Reproductive Disorders

Normal reproductive cycles in women require the integrated function of the hypothalamus, pituitary and ovaries. The hypothalamic component of the reproductive system can be assessed directly in lower animal species by measurement of gonadotropin releasing hormone (GnRH) directly from pituitary portal blood and recording of multiunit activity from the median ...

Phase N/A

Investigation of the Genetic Causes of Kallmann Syndrome and Reproductive Disorders

Overview Our work is divided into two main areas of investigation: the discovery of new, yet-undiscovered genes for conditions of early (i.e. precocious) puberty, delayed puberty, absence of pubertal development (i.e. Kallmann syndrome) as well as normal puberty that is accompanied by an altered reproductive system later in life (i.e. ...

Phase N/A

Intrauterine Balloon Therapy to Prevent the Recurrence of Intrauterine Adhesions

Patients The patients will be recruited from the Hysteroscopy Center of the Fuxing Hospital, Beijing, China. Before the surgery all patients with suspected Asherman syndrome will undergo preoperative evaluations, including a detailed history of the menstrual pattern, any previous intrauterine surgery, and reproductive history, as well as trans-vaginal ultrasonography. The ...
