Study of Sperm Molecular Factors Implicated in Male Fertility

Male Infertility

Sperm analysis following World Health Organization guidelines is unable to explain the molecular causes of male infertility when basic sperm parameters are within a normal range and women do not present gynaecological pathology. Subsequently, there is a need for accurate diagnostic tools in this sense and microarray technology applied to sperm analysis emerges as a promising field

Study of Psychosexual Impact of Cancer-Related Infertility in Women: Third Party Reproductive Assistance...

Cervical CancerEndometrial Cancer5 more

This study aims to learn about the needs and feelings of women who are infertile. Being infertile means not being able to have a child without the help of a third party. There are other options for building a family. The researchers are interested in the participants' thoughts about these options and want to learn about the experiences of infertile women due to cancer treatment as well as women who are infertile due to other causes. The researchers hope that what they learn will allow them to better care for infertile women in the future.

Study of Axillary Skin Temperature as a Marker of Ovulation

Infertility

Infertility is the most common reason women (aged 20-45yrs)see their GP, affecting 1 in 7 couples. Measuring basal body temperature is a technique that has been used since the 1930's to attempt to predict ovulation. Current NICE guidelines don't recommend the use of BBT charts to predict ovulation, as it has not been established to reliably confirm ovulation. The DuoFertility sensor a CE marked Class la device provides a continuous accurate measure of axilla temperature whilst worn under the arm. The investigators plan to compare the temperature measurements of the DuoFertility sensor with the gold standard transvaginal ultrasound scan obtained during 10 infertile women's menstrual cycles, up to 10 cycles per women. The investigators aim to investigate if continuous axillary skin temperature measurement obtained from the DuoFertility sensor, provides comparable results for identifying the occurrence of ovulation as the gold standard transvaginal ultrasound scan.

Genetic Causes of Male Infertility

Male Infertility

This study is being conducted at the University Hospital of Lund University in Malmo, Sweden, in collaboration with the U.S. National Institute of Child Health and Human Development. The study will try to identify genetic causes of impaired sperm production and male infertility. It will focus on the possible role of the MTHFR and CBS genes, which regulate absorption and metabolism of the vitamin, folate in infertility. If the nutritional intake or metabolism of this vitamin is related to male infertility, then this cause of infertility would be potentially curable. Fertile and infertile men between 20 and 45 years of age may be eligible for this study. Criteria include the following: Fertile men: men whose partners are younger than age 40 and are attending Lund University prenatal clinic; who have fathered one or more pregnancies and who stopped birth control to achieve the present pregnancy; who achieved the present pregnancy in less than 12 months of unprotected intercourse. Infertile men: men referred to the Scandian Andrology Centre whose infertility is unexplained, whose partners are younger than age 40 and who have had regular sexual intercourse without contraception for at least 12 months without achieving a pregnancy. All participants will have the following tests and procedures: Complete a questionnaire providing information about their reproductive and medical history and recent dietary history; Provide blood samples for analysis of red cell folate, plasma folate, plasma homocysteine, plasma B12, and for genetic evaluation; Provide a semen sample for routine analysis, including volume, sperm concentration, sperm motility, and sperm morphology. In addition, infertile men will undergo a physical examination and review of their medical records.

Psychosocial Impact of Cancer-Related Female Infertility

Hodgkin's DiseaseCervical Cancer2 more

The success of cancer treatment combined with the trend to delay childbearing is increasing the numbers of women survivors whose childbearing has been interrupted by cancer. For some, treatment has resulted in infertility. Others have been advised to delay pregnancy until a certain follow-up interval or have new fears that pregnancy could be a risk to maternal health. Not least is the concern that children born after a mother's cancer would face increased risks for birth defects or cancer. The specific aims of this project are as follows: To measure the impact of cancer-related interruption of childbearing on women's long-term emotional well-being and health-related quality of life, over and above other demographic and cancer-related factors To find out if becoming a biological or social mother after cancer treatment decreases the long-term psychosocial impact of interrupted childbearing compared to remaining childless To refine the psychometric properties of questionnaires for female cancer survivors measuring Distress about Cancer-Related Childbearing Issues and Attitudes towards Parenthood after Cancer To define targets for a future intervention to improve female survivors' knowledge about childbearing after cancer, decrease distress associated with interrupted childbearing, and promote peer support.

Development of a Microbiome Non-invasive Diagnosis Tool

Infertility of Uterine Origin

Although the endometrium tissue has been traditionally considered free of bacteria, recent studies have documented the presence of an endometrial microbiome. In a pilot study conducted by our research team, the microorganisms present in the endometrium were analysed in samples of endometrial fluid (EF) using next generation sequencing (NGS).Consistent with previously published studies, in normal conditions the endometrium is mainly composed of different species of the genus Lactobacillus. It was further noted that the presence of other pathogenic bacteria such as Streptococcus, and/or Gardnerella may alter the endometrial microbiome and can disrupt the uterine environment, affecting implantation rates and pregnancy success. This project aims to validate the microbiome found in the endometrium of women of reproductive age and try to corroborate the relationship between the endometrial microbiome and the reproductive outcomes in patients undergoing assisted reproduction treatment (ART). The use of Endometrial Receptivity Analysis (ERA) tool, together with the analysis of the endometrial flora before the embryo transfer will allow to evaluate the impact of the presence of endometrial pathogens on implantation in receptive patients. Therefore, the focus of this project is the development and clinical validation of a non-invasive diagnosis tool to analyse the microbiota, adding the microbiome study to the ERA analysis.

Predictive Value of Embryonic Testing

Infertility

The primary objective of this study is to determine the predictive value of preimplantation genetic screening (PGS) as a marker of embryonic competence. Secondary objectives are to define the related or independent predictive values of other proposed markers of embryonic and maternal reproductive competence in assisted reproductive technology (ART) cycles.

Endometrial Effects of Lipiodol

Female Infertility

The goal is to investigate whether endometrial flushing with Lipiodol enhances fertility. Therefore, anatomo-pathological, histochemical and transcriptional changes of the endometrium after Lipiodol bathing in a general population of healthy volunteers will be determined.

The Transition From Blastomere to Trophectoderm Biopsy: Comparing Two PGS Strategies

InfertilityPreimplantation Genetic Screening

Shortly after the implementation of Comprehensive Chromosome Screening (CCS) techniques for Preimplantation Genetic Screening (PGS) came the transition in biopsy timing. Trophectoderm biopsy is meant to overcome the limitations of cleavage stage biopsy and single cell analysis.
