Pros And Cons Of Fertility

1393 Words6 Pages

Fertility is the capacity to conceive or to induce conception. INFERTILITY is the inability to conceive after one year of sexual relations without contraception, or the inability to carry pregnancy to a live birth. It affects about one in six couples of childbearing age. STELILITY is complete inability to conceive children, and is relatively rare. Free Dictionary by Farlex
Humans are constantly exposed to a range of chemicals and toxins in their environment which can affect their health, including their reproductive health. For men, a range of environmental exposures are associated with reduced sperm concentration and quality. Men whose sperm is sub-optimal in either quantity or quality are less likely to conceive, and will, on average, take …show more content…

For example, a longitudinal study, which compared the semen samples of men with varying exposures to organophosphorus pesticides found that men with the highest exposure to these pesticides had the poorest sperm quality.
Another study of men attending an Argentinean infertility clinic found a link between pesticide exposure and sperm concentration, output and motility less than would be expected. The greater an individual’s exposure to pesticides, the more likely their sperm concentration, output, motility and proportion of morphologically normal sperm would be reduced. Exposure to glycol ether has also been shown to increase the risk of suboptimal sperm production. There are numerous pesticides which have not been studied in relation to male fertility and further research regarding these is necessary.
Testicular trauma can negatively affect spermatogenesis, however scientists do not yet fully understand …show more content…

Cadmium is a ubiquitous heavy trace metal toxicant and is well known as an industrial pollutant. Exposures to cadmium have been reported to reduce male fertility. Chromium is an important heavy metal which possesses several industrial applications Occupational exposure to chromium leads to alteration of semen status and may adversely affect the reproductive success of exposed workers. Lead is the most significant toxin of the heavy metals. Industrial decisions, such as the addition of lead to paints, dyes, and gasoline, have created an epidemic of lead poisonings. Lead is a naturally occurring substance and can be found in organic and inorganic forms. Lead is a reproductive toxicant detrimental to human semen quality. Decreased sperm count, motility, acid phosphatase, succinic dehydrogenase, fructose, surface reaction of sperm head DNA besides increasing abnormal sperms was reported in occupational exposure of lead in printing press workers in India. Higher lead level lowers sperm’s ability to bind and fertilize the egg. Mercury, widely used in modern technology and industrial revolution, has become an important pollutant for animals and humans. Mercury intoxication has been associated with male reproductive toxicity in experimental animals and mercury may have the potential to produce adverse effects on fertility of men. In a small population in India, it was found

    The article I chose is “Penn: Stressed Dads Affect Offspring Brain Development through Sperm MicroRNA” by Katherine Unger Baillie. Tracy L. Bale a professor of neuroscience at Penn’s School of Veterinary Medicine and Perelman School of Medicine is leading a study on how the level of stress can affect offspring’s through sperm. Professor Bale researched on male mice, and to elevate their stress levels she exposed them to a predator’s odor such as urine from a fox and/or transferring them to different cages. She then compared the sperm to the unstressed male mice and noticed an increase of nine miRs from the stress exposed mice. miRs prevent RNAs from translating into proteins.

In addition to the changing landscape, cancer, especially breast cancer, has increased in the prairies of Illinois and pesticides usage may cause. Much of the discussion first begin with the change of landscape as the prairies of Illinois has become a place for farming and pesticides. As farming became an important aspect of Illinois, pesticides were created to remove any bugs or insects from the product that is being farmed. A few pesticides formulas that came to be are atrazine, dichloro diphenyl trichloroethane (DDT), and polychlorinated biphenyls (PCBs).

    The first recorded account of contraceptives was in 3000 BC when men formulated condoms out of fish bladders and linen sheaths (“A Brief History of Birth Control in the U.S.-Our Bodies Ourselves”). The fact that people have felt the need for contraceptives since 3000 BC is a good testament to the need for modern day ways to prevent pregnancy. According to the same article, in the 1500’s the first spermicide was developed and used, and in 1838 the first modernized rubber condom was invented. After centuries of using different forms of birth control, in 1960, the first oral contraceptive, which was called Enovid, went on the market and was approved by the Food and Drug Administration (FDA). Only eight years later, the inter-uterine device (IUD) was developed and went on the market as the products of Lippes Loop and Copper 7.

    At this time, there is little to no evidence that these pesticides are increasing yields from plants they are applied to. However, there has been evidence of the pesticides killing bees or causing damage to their nervous systems, which impedes their ability to forage and fly. Harvard’s T.H. Chan School of Public Health preformed a study which found that 70% of pollen and honey collected from local bees contained at least trace amounts of neonicotinoids. Levels found from these samples were enough to cause detrimental health effects. In a separate study, they found that over half of plants at a major garden store contained neonicotinoids.

They also argue that IVF “dehumanize women and reduce them to empty vessels waiting to be filled with babies for the benefit of men” (Farris Naff 19). They believe that women go through the process of IVF because they want to satisfy their partner instead of themselves. Even though, IVF can be convenient for women, it is known that IVF can have some bad outcomes to some.

    Seminal oxidative stress and testicular apoptosis both are well-documented causes of increased sperm nuclear DNA fragmentation. Higher rates of sperm nuclear DNA fragmentation lead to lower fertility rates, both during natural and assisted reproduction [4]. This study aimed to assess sperm DNA damage in varicocele patients. Patients and methods This study was carried out on 20 infertile male patients having varicocele (the duration of infertility ranged from 1 to 15 years). They were collected from the Outpatient Clinic of the Dermatology and Venereology Department, Tanta University Hospital.

Cadmium exposure and its accumulation are known to impair spermatogenesis, sperm function and lead to impaired reproductive potential in men( Goodwin et
