Sperm Penetration TestsSperm Penetration test evaluates whether a mans sperm can travel through cervical mucus. It is one of the test done to determine the cause of infertility and whether it is related to a problem with the mans sperm or a womans mucous. During the womans ovulation, samples of her cervical mucus and the mans semen are collected for this test. In the lab, the semen is added to the mucus in a tube. After sometime, the distance that the sperm have traveled is measured. Sperm penetration tests evaluate whether a mans sperm can travel through cervical mucus or whether the sperm can penetrate an egg. For a sperm to fertilize an egg ovum, the sperm must penetrate the mucus at the opening to the cervix and travel through it into the uterus and up the fallopian tube. In the fallopian tube, it must penetrate and fertilize the egg. There are many types of sperm penetration tests, and the value of the results are directly related to your health professionals experience in evaluating the tests. Sperm penetration tests are usually used for couples whose treatment decisions will be influenced by the results of the test. Sperm penetration tests consists of the sperm mucus penetration test and the sperm penetration assay (also called the hamster zona-free ovum test or hamster test).
Sperm / semenA low sperm concentration may be an indicator of infertility, but may also be due to a temporary or more long lasting medical condition or physical factor that does not cause infertility even if your sperm concentration is low. You should consult your physician if you obtain two negative results.
It is sometimes hard to know whether the sperm problem is the only cause, or just a contributing cause to the infertility. Part of the problem is that numbers are just numbers:
Men with very low sperm counts can sometimes have children Some men with normal sperm counts can be infertile
One of the biggest concerns of couples involved in an infertility work up relates to the status of the male partners sperm evaluation. While the thorough evaluation of sperm and sperm function should be given high priority in any infertility evaluation, we have found from our web page interactions with patients that often times the couple are told very little related to test results in this area. Or, in other cases, we hear of couples being told about high numbers of abnormal sperm, or low numbers of good sperm with little additional information about what those results mean to their chances for conception. Sperm fertility test results should be in a fertile man. While there is no substitute for the evaluation of semen and sperm testing results by a highly trained and specialized professional, the truth is that many modern laboratories and even some very well qualified physicians have not kept totally abreast of our changing understanding of sperm function, and our new and evolving views of fertile sperm test results.
 2008-11-15 Straight-from-the-hip talk on gay marriage Asbury Park PressThe state shouldnt have a genitalia test to enter into a contract. Its said that about 10 percent of the population is gay. That means allowing gay marriage wont affect 90 percent of us. While youre at it, outlaw sperm and egg donation, and, of course, surrogate mothers. You either believe marriage is about procreation or you dont. This country has a huge problem with infidelity and divorce. Protest that, and leave us alone. EDITORS NOTE: Voters in California, Arizona and Florida last week backed constitutional bans on gay marriage, while legalization of gay marriage took effect in Connecticut. New Jersey lawmakers will be taking up the debate sometime soon. - Opinion Monmouth and Ocean counties NJ News local news headlines stories world news
2008-11-15 Invisible transplant organs now in sight - health New ScientistHas stalled through lack of funding and problems with the cloning technique used to engineer the pigs. Now there is a simpler way. The new technique will alter the DNA in a boars sperm cells, and therefore in any future offspring, by injecting a virus into its testicles carrying the desired genes - such as those used to "disguise" pig organs. When the boars breed naturally, they should pass on the genetic changes to their piglets. Organs that arent seen by the immune system, and therefore wont be rejected, could be ready in a decade, thanks to a faster way of genetically

2008-11-15 First at-home test for vasectomized men proves accurate, easyWashington (ANI): Researchers from University of Virginia Health System have found that SpermCheck Vasectomy, the first-at-home test for detecting low concentrations of sperm, can spot sperm count with 96 percent accuracy. Traditionally, the process has involved bringing semen samples to a physicians office or laboratory at two- and three-month intervals after the procedure, but with the new test men would be able to monitor the sperm count on their own, that to sitting at home. The test achieved an accuracy rate of 96 percent in identifying whether sperm counts were greater or less than a threshold of 250,000 sperm per ml - a level associated with little or no risk of causing pregnancy.

2008-11-15 First person: I could have 300 siblings Life and style The GuardianToday, UK regulations stipulate that the maximum number of families that can use sperm from the same donor is 10, but this week the British Fertility Society is pushing for more. It says there is a shortage of sperm donors, as if this were a serious public concern. Radical reform of the current system is needed, it says, preferably the removal of donor anonymity in light of the fact that currently 35 pct. of potential donors drop out after their first inquiry. But I see this dropout rate as good. I think those men who decide, upon reflection, that its not for them are to be supported and admired. If you compare donor insemination to giving your child up for adoption, you see it for what it is. As a child, Jo Rose discovered her father was a sperm donor. At 36, she still hasnt found him.

2008-11-12 Study Finds Antidepressant Use May Cause Male Infertility - Health News Current Health News Medical NewsThe sperm appears to be damaged by a slowing down of their transport through the body, "a novel mechanism of damage," he said. "Most agents affect fertility by knocking down sperm production. Slowing down sperm transport can allow sperm to be damaged (by higher temperatures, or just getting too old being ejaculated after they should have been). " Abnormal sperm DNA integrity even affects pregnancy outcomes of the most advanced assisted reproductive technologies, such as in vitro fertilization (IVF)," she added. "In fact, it is the only male factor finding that has been shown to affect intracytoplasmic sperm injection (ICSI) results. " Study Finds Antidepressant Use May Cause Male Infertility, Treatment with paroxetine (Paxil), which belongs to the selective serotonin reuptake inhibitor (SSRI) class of antidepressant drugs, increases DNA fragmentation in sperm, which may lead to male infertility. - Antidepressant paxil male infertility fertility health news current health news medical news
2008-11-11 Best way to make a baby - ChronicleLiveMuch of this advice doesnt just apply to the ladies, some of it is important for men. Smoking and alcohol consumption decrease the quality and the quantity of sperm. Wearing loose underwear keeps vital areas cool, which improves the chance of conception.

2008-11-10Sperm and egg samples are used to form an embryo in a test tube, and a single cell is extracted from each when it has aged to a size of eight cells. A cell can be screened for susceptibility to hundreds of disorders, and a cell with no irregularities can have its embryo put into a uterus to attempt a pregnancy. Even if a commercial test shows a genetic predisposition to a disorder, the best-case scenario is a linkage, and it doesnt mean a child will have the disorder," said Craig Holdrege, director of the Nature Institute.
2008-11-08 PCBs affect learning by stunting brain nerve development. and mdash; Environmental Health NewsMother rats exposed to the higher PCB concentration had twice as many males as females. Males had significantly enlarged prostates at the low, but not the high PCB dose. Some endpoints that were not affected include size of reproductive organs (excluding the prostate), sperm counts and estrogen and testosterone hormone concentrations. Various brain and reproductive aspects were measured in the rat pups to determine effects of the exposure. The researchers examined body weight, male to female sex ratios of the litters, prostate size in males, sperm count, size of reproductive organs, genes known to be affected by PCB exposure and several other endpoints. Thyroid and estrogen hormone levels were also measured because previous studies show that PCBs can interfere with thyroid function and estrogen production. www.environmentalhealthnews.org In a unique study, researchers show that exposure to PCBs in rats interferes with learning by stopping the brain from forming complex nerve networks essential for memory and intellect. In essence, the exposure prevented nerves in the rats brains from changing as a result of experience. This effect could underpin some of the impacts that PCBs have on childrens ability to learn.
