Filter by:The study objectives are described below: 1. Obtain serum specimens collected for one ovulatory cycle or a maximum of 33 days, but not to exceed a total of 550 ml of whole blood per subject from a minimum of 60 healthy, premenopausal subjects. Specimens will be used to determine a reference range for estradiol, FSH, LH, and progesterone assays, used as an aid in the assessment of fertility in adult, premenopausal women. 2. To store any remaining specimens for use in future assay development and to evaluate as yet undetermined assays for the development of IVDs, including additional estradiol, FSH, LH, and progesterone assays.
Many women and men in fertile age are at risk for sexual transmitted infections and unwanted pregnancies, and have insufficient knowledge of health promoting lifestyle prior to conception. There is a need to increase awareness among people in fertile age about how sexual risk-taking and unhealthy lifestyle can negatively affect fertility and pregnancy outcomes. Previous studies on preconception health and care have mainly focused on women. The aim of our study was to investigate if Reproductive Life Plan-based counseling with a midwife could increase men's reproductive knowledge. The second aim was to evaluate men's experiences of the intervention.
The investigators propose to test the efficacy of the Reproductive Health Survivorship Care Plan (SCP-R), a novel survivorship care tool to meet the reproductive health needs of young breast cancer survivors (YBCS). Most YBCS undergo chemotherapy and/or endocrine therapy, treatments that impair ovarian function and result in significant reproductive health late effects. These late effects include symptoms of estrogen deprivation such as hot flashes, fertility concerns, limited contraception options and sexual problems. Together they have a major, negative impact on quality of life. Despite substantial research, treatment guidelines and clinical expertise on these issues, most YBCS and their healthcare providers have limited guidance on how best to manage these reproductive health late effects. The research team has generated a practical, accessible, evidence-based reproductive health survivorship care plan (the SCP-R) for YBCS and their providers to address this deficit in survivorship care. This clinical trial will test if YBCS who receive the web-based SCP-R are more likely than controls to improve on at least one of these reproductive health issues: hot flashes, sexual health, fertility concerns, and contraception.
Sperm freezing has been employed for decades for male fertility preservation in cases of foreseeable or unexpected loss of fertility to guarantee future paternity, and also as a complement of assisted reproduction techniques. Sperm quality after thawing is highly variable, even among consecutive samples from the same individual, with mean survival rates around 40%. To date, the molecular basis of the adequate resistance or intolerance to freezing/thawing protocols is unknown, and its knowledge can lead to improvement in the selection of the samples to be frozen and also in the adequate supplement of cryopreservation media. Microarray analysis provides a powerful tool to address the molecular explanation beyond this behaviour, yielding results about comparative messenger ribonucleic acid (mRNA)expression under the two different biological conditions: optimal and suboptimal survival. Then, the aim of the investigators' study is to determine the genomic profile of sperm samples depending on their survival resistance to cryopreservation, to determine genes involved in cryodamage sensitivity.
Excess maternal weight, especially obesity, influences almost every aspect of fertility, from conception to problems during pregnancy. The investigators will use novel statistical methods to clarify the hormonal changes behind reproductive health conditions. A better understanding of reproductive hormonal changes in obese women may offer a way to identify new treatments.
This study is for couples pursuing in vitro fertilization (IVF) with preimplantation genetic screening (PGS) of embryos to achieve pregnancy. The objective of this clinical trial is to study the effect of mono-menotropins for COS versus recombinant follicle stimulating hormone (rFSH) on cleavage-stage and blastocyst embryo quality after IVF. Embryo quality parameters include conventional embryo grade, early embryo viability assessment (Eeva) time-lapse parameters, and chromosomal aneuploidy rates after PGS. This pilot study is expected to significantly contribute to optimization of treatment regimens and stimulation protocols to optimize embryo quality.
The purpose of the study was to explore the added value of adjunctive use of Early Embryo Viability Assessment (Eeva) with morphological grading in identifying optimal embryos for transfer.
Fertility knowledge and awareness is considered insufficient in women of reproductive age from developed countries. The objective of this study is to evaluate if educational interventions in oocyte donors increase on their level of fertility knowledge and awareness.
Compare FDG PET-CT parameters between azoospermia patients having an extraction of sperm cells by positive testicular extraction and those with a negative extraction.
In cattle less than 10% of the embryos develop to the blastocyst stage when embryos are cultured individually, however when bovine embryos are cultured in groups a typical 25-35% of blastocysts can be observed. This tendency, i.e. improved embryo development in group culture, has also been demonstrated in other mammalian species, such as mouse, cat and human. The main reason for this beneficial outcome of group culture has been ascribed to the presence of autocrine factors, which are factors secreted by preimplantation embryos that act upon the embryo itself or the neighboring embryos . Although group culture systems are common in in vitro production systems for animal embryos, it is rarely done in human settings, where individual follow-up of the embryo during the whole culture period is of utmost importance. Recently a CE-labelled culture device has been designed for human embryos, that allow to combine the benefits of both group culture approaches and individual culture. The WOW dish is commercially available by Primo Vision and consists of 9 small microwells on the bottom of the plate, so that the embryos can be cultivated individually in a microwell, but covered by the same drop of culture medium. In this clinical randomized trial, 158 patients will be included of which half of the fertilized oocytes will be cultured individually (standard culture system) and half of the fertilized oocytes will be cultured in group in a WOW dish, both during five days of culture. The aim of this study is to increase the number of blastocysts suitable for transfer or cryopreservation by culturing the embryos in WOW dishes.
