A new study, published in the journal Science Advances, found that the female reproductive tract may trap slower moving sperm, allowing only the fastest moving sperm to reach the egg.
Researchers from Cornell University used several models and computer stimulations to try to better understand how sperm travel through the cervix, into the uterus, and then into the fallopian tubes …
A new test developed by Androvia LifeSciences, called a Cap-Score, may help predict whether or not a man’s sperm is able to fertilize an egg. The Cap-Score was developed by the Travis lab at the Baker Institute for Animal Health and Cornell University’s College of Veterinary Medicine, who recently published their Cap-Score data in the journal Molecular Reproduction and Development…
A new study presented at ENDO 2018, the Endocrine Society’s 100th annual meeting in Chicago, IL, found that low sperm count may not only be a problem for fertility, but is also a marker for a man’s general health.
The study looked at 5,177 male partners of infertile couples in Italy and found that low sperm counts were associated with …
An Argentinian review of multiple animal studies is suggesting that antihistamines, found in common allergy medications, may affect male fertility. The study, published in the journal Reproduction, found that antihistamine use could decrease sperm motility and alter sperm morphology.
The study found several papers that reported impaired testicular function in animal studies after antihistamine exposure. These papers found that …
This year marks the 50th anniversary of the U.S. Food and Drug Administration approving the sale and marketing of clomiphene citrate (Clomid) for the “treatment of ovulatory dysfunction in women desiring pregnancy”. At the time, this was a huge breakthrough for couples who were desperate to conceive their own child. For many patients, it was a “wonder drug”.
Prior to …
This is a question that reproductive endocrinologists have studied and debated since the technique of intrauterine insemination was first developed.
A study reported in the September 2010 issue of Fertility and Sterility again looks at the effect of timing of an IUI on the success rate.
They divided the patients into three groups: patients in group 1 underwent a single preovulatory …
Conventional treatment for couples experiencing unexplained infertility has usually consisted of three cycles of clomiphene (CC) with IUI, followed by three cycles of gonadotropins (FSH) with IUI and then IVF if those conservative measures did not work.
A study in the August 2010 issue of Fertility & Sterility looks at the time it took to establish a pregnancy that led to …
