CONCLUSIONSSeveral studies indicate that there is a relationship between the exposure of man to the radiation of cell phones and the decrease of the cells of reproduction of man, to a greater exposure, the levels of count are smaller. These studies show a decline in semen quality and an increased risk of male subfertility where the possible harmful effect of this phenomenon has been posed by the possible harmful effects on the reproductive organs of certain environmental factors such as ionizing radiation, high temperature , Tobacco, alcohol and the use of pesticides, solvents and others. There is a threshold dose below which the effect or lesions do not occur, or if they occur they will be of low severity. The higher the dose received the more severe the injury will be.The most radiosensitive part of the male reproductive system is the testicle and, within it, the spermatogonies, since they fulfill the requirements expressed in the Basic Law of cellular radiosensitivity. The primary effect of radiation on the testis is the decrease in the number of spermatogonia, which causes a subsequent decrease in the number of spermatozoa. There is a certain period of temporary fertility, followed by a phase of sterility, more or less durable depending on the dose received.The rest of the cells of the glandular interstitium are more resistant to radiation, so these sterility frames are not accompanied by the alterations produced by insufficient secretion of male hormones, and the secondary sexual characters are kept intact.When studying the sixth semester of  CECyT # 15 from 17 to 20 years of age exposed to the ionizing and non-ionizing radiation of cell phones, the results showed that the patients are within normal morphology and mobility values , However they are elevated in a certain way, if patients are constantly using the cell phone in the pocket or other place near the reproductive system, they are much more likely to infer infertility than those who do not carry it in the pocket, this is Can associate that they were exposed to this radiation for a mean lapse, so it is important not to keep the cell in the pocket of the pants in a usual way due to the constant radiation emitted by these devices.With this, it is concluded that the men who keep their telephone sets in the bags of their pants or the belt have a low amount of sperm but nevertheless are within the established reference values. It is possible to mention that the hypothesis was not verified because it was not possible to control the time that they took using the cell phone, much less the place where they carry his cell phone.

ABSTRACT.

Mexico is a country which more than 80% of Mexicans have a SmartPhone device and four out of ten in a smartphone, so that mobile marketing is a sector that is clearly expanding.

At least one study has shown that cell phones damage sperm's viability and ability to swim, effectively lowering your sperm count. This is believed to apply to cell phones that are transmitting or are in talk mode and that are in close proximity to men's lower halves.

Most adults worldwide own mobile phones, and about 14 percent of couples in middle- and high-income nations have difficulty conceiving, the researchers said. They also noted that previous studies have suggested radio-frequency electromagnetic radiation emitted by cellphones can harm male fertility.

 The use of personal radiotelephones is increasing rapidly, with increasing number of base stations, often located in public areas. Part of the antenna radiated energy is absorbed by the head.

The most common cause of male infertility is a varicocele (enlarged scrotum) on one or both sides. The relationship between constant use between mobile phones and male infertility is one: radiation affects the morphological characteristics of the affected spermatozoa characteristics for fertilization of the ovule. The most radio-sensitive part of the male reproductive system is the testicle and, within it, the Spermatogonia, since they fulfill the requirements expressed in the Basic Law of cellular radiosensitivity. The effects of radiation on the organism can be classified into genetic and somatic effects. The genetic effects are those that affect the germinal cells and, given the function of these, can be transmitted to the offspring. However, the somatic effects are those that only affect the cells of the irradiated individual. Deterministic effects are characterized because their severity depends on the dose of absorbed radiation.

Mark Zuckerberg, the American computer programmer, who was born in the NRew York in 1984, was one of the founders of facebbok.









In his teen, he began to write software programs as a hobby. After school, he went to Harvard, where he studied computer science and sociology. While he was there he created a website called Facemash, which allowed students to share a photo .It was shut down by university, but it inspired him to created facebook, which he launched from his room in 2004

He left Harvard and moved to California with Dustin Moskovitz,  who had been his roommate  and together they made facebook an international success

In 2012- Zuckerberg married Priscilla Chan who had dated for nine years

Dear Sir. Perez

I´m writing yo you because last month, I ordener a 2 x 3 cm components from your online store( order  F345/01 OF 2 March). Before placing the order I read all the conditions very carefully  and the item was stock and with the dimension that I want.

Three days passed and arrived a  3 x 2 cm components and the D70 motor you sent doesn´t work. and another important thing is that I noticed that payment had been taken from my credit chard.

I phoned your customer sevice line and the person that I spoke to, Tori, was very rude. But she said  it must be a  packaging error for the components but se couldn't explain why the money had been taken from my chard.

I have bougth many things from you over the years and I have always had a good service,  I don't know what happened this time but I´m sure you will be able to resolve the situation in a satisfactory way.

I look forward the hearing from you.

Your sincerely.

Hank Weston.
