Infertility is a significant and common problem; approximately 9% of couples throughout the world are infertile with 56% of couples needing treatment (Boivin et al, 2007). Study by Mike Hull demonstrated that sperm dysfunction is the single most common cause of male infertility (Hull, 1985). This observation has been confirmed by other studies with report that dysfunctional sperm may exist against entirely normal semen analysis and conversely normal sperm function with very poor samples (oligozoospermia) (3-4 in Cris paper). Without a clear understanding at cellular and molecular level of sperm dysfunction, the only effective treatment for these cases is assisted reproductive technology (ART). It is generally accepted that diagnostic and …show more content…
Correlation with other function
A plethora of clinical studies on hyperactivation have suggested that (1) the percentage of hyperactivated sperm correlates significantly with fertilisation rate both in vivo and in vitro, however, study by Guerin and colleagues failed to find a significant correlation between hyperactivation and IVF outcomes (2) the potential differences in proportion of hyperactivated cells (spontaneous and in response to physiological or artificial stimulants) in men with proven fertility and subfertile patients. Although these clinical observations suggest that hyperactivation has some predictive value for fertilisatin and a significant role in male fertility, measuring hyperactivation levels is not robust enough to be used clinically. A main reason for this is lack of uniform accepted criteria used to define hyperactivation (oehngier, 2000), making comparison data from different studies impossible. As such, there is an urgent need to validate hyperactivation assay before draw any conclusion of its application clinically. Additionally, all hyperactivation and sperm kinematic analysis should follow guidelines for hyperactivation assessments and using appropriate quality control procedures for application of CASA (computer-aided sperm analyser) as recommended by ESHRE Andrology Special Interest Group in 1998 to generate reliable results.

There are risks associated with these types of ART. The use of any ovulation induction therapy can cause a woman’s ovary to swell up to 10 times its normal size (Cowley and Springen, 1997). It is also possible for up to 40 eggs, as opposed to the normal one, to be released in one cycle (Cowley and Springen, 1997). This results in a much higher risk for the conception of a multiple fetus pregnancy. There is a 5%-10% chance of a multiple pregnancy with the use of clomiphene (Jacobs, 2004). This is significantly higher than the 1% rate of occurrence of twins in unassisted pregnancies (Dr. Joseph F. Smith Medical Library, 2003). In about 1 out of 5 pregnancies achieved using FSH injection therapy the result is a multiple birth (Brown, 2001). In an attempt to avoid the conception of these multiple fetus pregnancies, it is suggested that the physicians monitor the number of eggs
Infertility is the incapability or failure conceive after one year of unprotected sexual intercourse or due to an impairment a person’s capacity to reproduce either as an individual or with his/her partner. While infertility can cause issues in men and women, women are more susceptible to having issues conceiving naturally. 1 in 8 women (or 12% of married couples) have trouble getting pregnant or sustaining a pregnancy (2006-2010 National Survey of Family Growth, CDC). There is a process in which three stages such as ovulation, fertilization, and implantation that a women’s body must go through to get pregnant. When there are issues in these stages, infertility is diagnosed and examined by a doctor therefore, making it hard to conceive a baby naturally. Throughout this paper, I will explain three common causes of infertility in females like endometriosis, sexual transmitted diseases, and poor nutrition.
"Clinical tests have demonstrated that individuals who experience the ill effects of spermafortis have sperm counts near a thousand times more powerful and rich in spermatozoids than the normal man," he clarifies. "This sort of semen is genuinely like of those warm blooded animals, for example, dolphins, manatees and seals and has properties that make it unfathomably impervious to water. This condition could clarify what happened for this situation yet clinical trials and further tests would be expected to demonstrate this hypothesis," he told neighborhood reporters.
The technology of the world today is fast-paced, fascinating, and extremely helpful in many cases. The ever-changing field of medical technology has changed and/or saved the lives of countless people. Doctors are able to perform procedures on patients today that were unheard of only 5 years ago. However, not all procedures and practices may be biblically ethical. Christians must decide which procedures are God honoring and which ones are not, especially when infertility is involved. Dr. Rae mentioned five theological foundations for bioethics that believers should evaluate in order to discern the uses of technology in the interference of the natural process of conception. Dr. Rae’s list consisted of the following: Dominion Mandate, Impact of

Thank you for choosing IVF Australia, we bride on ourselves on our success rates and price. This sheet has all the essential information about the causes of infertility in both male and females, the treatments to these and different issues that may come with these procedures. Infertility is the inability to conceive a pregnancy after 12 month of unprotected sex. Infertility in male and females can occur from various reasons such us the production of sex cells(gametes) and hormonal issues as well as other reasons. Infertility is growing rapidly in today’s world, it is becoming a bigger and bigger problem in Australia as 1 in every 6 couples are effected by infertility (19). A solution to this growing problem is Assisted
Semen analysis is a test which is carried out in a hospital to test whether a couple is able to conceive a child. The semen analysis is usually performed on fertility by taking two samples at least seven days more of that samples are taken period two or three months. The sperm count and the semen which is in the male may change from day to day. The reason is that they may have some medical conditions which can affect the sperm levels. The test is done by taking some sample from the males’ semen and check if they are normal.
Infertility can be extremely challenging for couples to overcome. It can be not only physically draining, but emotionally and mentally as well. Infertility can be easily compared to a roller coaster, with emotions going up and down from hope and optimism plummeting down to frustration and even grief after many the couple has tried for a long period of time. While for me personally, I first think of women when I think of infertility, the men play a large role as well. They are also hoping for children and the biological reason for the infertility can be from either sex. Research has also shown that infertility can make physically difficult and cause anxiety in couples, which could led to increased difficulty in conceiving (Domar & Gordon,
Hypothalamic or pituitary disorder affects less than two percent of the males but it is still one of the causes. For men with gonad disorder, it is about thirty to forty percent chance that it is the cause of infertility. Sperm transport disorder may be a cause of infertility in men as well but the percentage is a low ten to fifteen. The most common cause of infertility in males is unknown and to the day, doctors are trying their best to figure something out. Using certain medications, history of sexually transmitted diseases and UTI’s may be causes of infertility as

Almost all men can become infertile because the tube that connects the testes and prostate gland (vas deferens) is either blocked with mucus or missing entirely. Some treatments might be useful for the possibility of them to become
In vitro fertilisation (IVF) marks a great step forward in medical technology, and Australia is a leader in the field. IVF is now a popular procedure for couples who are infertile or are having trouble conceiving. However, it raises ethical, moral and legal issues including the rights of an individual, property rights, the definition of human life, scientific experimentation versus a potential human life, religion, costs, and community, medical and taxpayer’s rights.

He has been married for six years and his wife has already undergone three unsuccessful attempts at artificial fertilisation and one unsuccessful attempt at in vitro
There are many causes for male and female to be infertile. Infertility in men is when they are unable to produce sperm." The key that tells this man is infertile is changing in hair growth." ( Web Med) "For male infertility there are many causes. There are three factors: genetic defects, hormonal imbalances, and anatomical problems. 90% of male infertility cases are due to low sperm count and poor sperm quality or both. Men who live a healthy life style are more likely to produce a healthy sperm. Smoking, alcohol, tight underwear, and stress are causes of infertility too. There is a small percentage of male infertility cause by hormonal problems. There also can
Infertility is widespread: about 7% of married couples in the United States are unable to conceive after 12 months of unprotected intercourse (Purdy, 2001, Bioethics of New Assisted Reproduction). In Vitro Fertilization is used when a women has irreparably damaged fallopian
