Fertility and prenatal attitudes towards pregnancy in women with eating disorders: results from the
Lifetime EDs are associated with fertility problems, unplanned pregnancies and negative attitudes to pregnancy. Health professionals should be aware of EDs when assessing fertility and providing treatment for this.
Conventional ovarian stimulation no longer exists: the age of individualized ovarian stimulation
Determining the agents for ovarian stimulation as well as the combination of them, the daily dose and duration according to some background information should be seen as the way to enhance safety and cost-effectiveness. This discussion paper aims to
Vitrification as an alternative means of cryopreserving ovarian tissue
Despite the encouraging results obtained with vitrification, it is necessary to understand how vitrification solutions and protocols can affect the ovarian tissue. Here, we summarize the principles of vitrification, discuss the advantages of vitrific
Effects of cryopreservation and density-gradient washing on phospholipase C zeta concentrations in h
These findings indicate that while DGW positively selects spermatozoa with detectable PLCζ:, cryopreservation has significant detrimental effects upon PLCζ: concentrations. Since reduced PLCζ: concentrations have been implicated in defic
Reconstitution of the Mouse Germ Cell Specification Pathway in Culture by Pluripotent Stem Cells
The generation of properly functioning gametes in vitro requires reconstitution of the multistepped pathway of germ cell development. We demonstrate here the generation of primordial germ cell-like cells (PGCLCs) in mice with robust capacity for sper
Risks to Offspring Associated With Advanced Paternal Age
In recent years, as industrialization and occupational subspecialization have increased, demands on the work force have also grown significantly. These demands, including increased vocational and educational training, have contributed to the trend fo
The Clinical Implementation of Sperm Chromosome Aneuploidy Testing: Pitfalls and Promises
Automated FISH imaging and analysis technology is now available and is beneficial in reducing technician time analyzing sperm aneuploidy. Emerging technologies, such comparative genomic hybridization, may be beneficial in further improving the qualit
Sperm Cryopreservation: Recent and Marked Increase in Use for Testicular Cancer Compared With Hodgki
In a public network of sperm banks, time trends in use of sperm cryopreservation by men with testicular cancer (TC) and Hodgkin disease (HD) were assessed from 1990 to 2004.
One Semen Sample or 2? Insights From a Study of Fertile Men
In clinical settings it is usually recommended that at least 2 semen samples are obtained, because this decreases the error rate in classifying men as fertile, subfertile, or infertile.
In the event of the unexpected death of a male patient, urologists may be called upon by the patient's partner, spouse, or relatives to perform a sperm extraction. This procedure, known as cadaveric sperm retrieval, is clouded by controversy and, in
A variety of sperm DNA damage evaluation techniques are currently available. These include the terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay, comet assay, sperm chromatin structure assay (SCSA), and others. Although there
Research Into Eating Disorders and Fertility Reveals Mixed Picture
Eating disorders such as anorexia and bulimia are associated with fertility problems and negative attitudes to pregnancy, according to a UK study. The research also revealed high rates of unplanned pregnancies in women with a history of anorexia, sug
How the Early Human Embryo Acquires Its Shape Through 'Organizer' Cells
How is it that a disc-like cluster of cells transforms within the first month of pregnancy into an elongated embryo? This mechanism is a mystery that people have tried to unravel for millennia.
Research Links Diet During Pregnancy to Breast Cancer Risk Reduction in Female Offspring
During pregnancy, women are counseled to refrain from consuming certain types of foods, beverages and medications in order to avoid jeopardizing the health and development of the fetus.
Women with a history of eating disorders may struggle to fall pregnant quickly, research suggests. They are also more than twice as likely to need fertility treatment, a study of more than 11,000 UK mothers has found.
Stem cell sperm study leads to successful mouse births
Fertility experts are hailing a mouse study in which working sperm cells were created from embryonic stem cells in mice as "hugely exciting".
Japanese researchers successfully implanted early sperm cells, made from the stem cells, into infertile mic
