Effect of Environmental Exposures on the Egg Fertilizing Ability of Human Sperm

Male InfertilityTesticular Diseases2 more

Our data indicate that environmental exposure to the heavy metal lead are more widespread than currently appreciated and that such exposures are associated with the production of human male subfertility. Lead's effects are observed in male partners of infertile couples attending an IVF clinical, in men acting as semen donors in an artificial insemination program and in men representative of the general public. Our goal is to identify the mechanism(s) underlying lead's anti-fertility action.

Validation of New Devices Against Ambient Electromagnetic Radiation

Male Infertility

Project Summary Cell phones have become indispensable devices in the investigator's daily life. These phones operate between 400 and 2000 MHz frequency bands and emit radiofrequency electromagnetic waves (EMW). Radio-frequency electro-magnetic field exposure from cell phones or other sources of microwaves have deleterious effects on sperm parameters (like sperm count, morphology, motility). Further, EMW radiation emitted by mobile phones affects cells and organelles, and results in disorientation of charged molecules within the cytosol and a distortion of electron flow along the internal membranes of the cells. These cellular changes results in the generation of ROS leading to oxidative stress, which in turn results in radiation-induced sperm DNA fragmentation. Radiation shield can help provide protection from high levels of EMW radiations deflecting, diverting, and absorbing the radiation between the user and the source. A new EMW radiation shield, Qi-Shield device developed by Waveguard GmbH (Bautzen, Germany) provides protection against the radiations emitted by the smartphone and laptop devices. Qi-Shield utilizes conductive fluids in a particular geometric arrangement intended to ameliorate the negative effects of EMW radiation. Study Aims: To evaluate the changes in the semen parameters from the use of Qi-Shield device in sham (control) and user groups To determine the molecular changes pertaining to sperm proteins from the use of Qi-Shield device in sham (control) and user groups Significance The negative health consequences of EMWs have been documented across a wide range of device types, exposure frequencies and doses (Giuliani, 2010), at field strengths substantially below the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines for permissible exposures. In the absence of a revision in the ICNIRP guidelines, near-term public exposures to EMWs will most certainly continue to increase, despite the scientific evidence suggesting more careful review and recommendations to limit exposure to electromagnetic fields as much as possible. At present, there is no veritable means for counteracting the negative health consequences of human-made EMWs, revealing an unmet need for a means of protecting from or ameliorating the negative effects of EMWs, and the need for devising strategies for creating safer living and working environments in a time of increasing EMW exposures. Positive results in this study would demonstrate a means of counteracting negative effects on human sperm due to EMWs. Documentation of protection due to the Qi-Shield devices would show proof of principle that a low-cost passive device, portable and without battery or mains power, can provide improvements in human sperm parameters, with promise for a means of counteracting EMW-reduced fertility in large numbers of people. Confirmation of changes on protein expression would provide data needed to identify specific pathways of action, insight that is necessary for a more detailed understanding of the mechanisms of action of the EMW protection effect. Taken together, these results would suggest further lines of study in EMW protection, and provide clinical support for the adoption of EMW-protecting devices in the home and workplace.

Attention to Variability During Infertility

InfertilityInfertility3 more

Infertility affects approximately one in seven couples, and it can be a devastating diagnosis and difficult experience for couples to endure. Ellen Langer, Ph.D., Director of the Langer Lab at Harvard, has spent several decades demonstrating evidence supporting a mind-body approach to improve wellbeing and overall functioning. Specifically, she asserts that Mindfulness in its most basic sense - paying attention in the moment - is enough to create both perceived (e.g., self-reported) and real (e.g., objective testing) change. Langer and her colleague, for example, demonstrated that "Trait mindfulness predicted the well-being of expecting mothers and better neonatal outcomes. Mindfulness training resulted in better health for the expecting mother". In this study, Mindfulness training refers to "attention to sensation variability." Such interventions are cost effective, minimally invasive, less time-consuming for practitioners and participants and generally easy to learn. Langer and her colleague's study refers to pregnancy. Infertility is unlike pregnancy in its exact clinical diagnosis. Nevertheless, similar to pregnancy, infertility is considered a clinical condition affecting the body, in this case the reproductive system. Therefore, based on the results of studies like Langer and her colleague's, that used participants with clinical conditions affecting the reproductive system, the investigators propose similar mindfulness intervention (attention to sensation variability) research with infertile individuals. However, the investigators intend to extend our examination to also include a treatment group with the partners of the infertile individuals, as little, if any research, has attempted to do so previously. The investigators hypothesize that state mindfulness (groups exposed to mindfulness intervention) will improve wellbeing in the infertile patient and her partner and that trait mindfulness will predict ability to become pregnant.

Influence of Culture Media on Clinical Outcomes in Poor Responders or Severe Male Infertility

Poor ResponderSevere Male Infertility3 more

In this study the suitability of two -sequential and single step- commercially available culture media from the same brand was compared. The aim of such study is to verify whether is possible to improve the efficiency of infertility treatments in those couples who usually have a high cycle cancellation rate, such as poor responder patients and severe male infertility. The study population is composed of couples attending the fertility clinic: to this purpose all those couples approaching IVF treatments with a diagnosis of OAT, cryptozoospermia, advanced maternal age and women with a "poor responder" diagnosis were recruited. IVF treatments were randomly set to be cultured either with two-step sequential media or with one-step media to acquire data concerning the ongoing embryo culture development and clinical outcomes.

A Clinical Evaluation of Semen Quality Using the MiOXSYS™ System 2.0

Male Infertility

The purpose of this study is to determine if elevations in oxidative stress, as measured by oxidation-reduction potential (ORP), can distinguish between semen samples from men with abnormal semen parameters from those with normal semen parameters. Static ORP (sORP) results, measured by the MiOXSYS System- a novel technology, will be compared to the current World Health Organization (WHO) semen analysis parameters (5th Edition WHO Laboratory Manual for the Examination and Processing of Human Semen [2010]).
