Infertility and Treatment - Essay Example Further it is also estimated that about 40% of infertility cases are due to some disorder in male partner, 40% involve a female factor, and the remainder involves both sexes. In women, problems can arise with either or both of gametogenesis and fertilization. As a result of these factors it can reduce or abolish the chances of pregnancy. Statistics suggest that ovulation failure either due to absent or infrequent menstrual cycles accounts for 20% of reported cases of difficulty in conception. Other problems that prevent conception in women include blockage of fallopian tubes, polycystic ovarian syndrome, hypothalamic dysfunction, luteal dysfunction, premature menopause, etc. Blockage of fallopian tubes: Female infertility due to blocked fallopian tubes can be detected by a simple technique called the hysterosalpingography. In this process a radio-opaque dye (methylene blue) is infused into the uterus. If the leakage of dye into the abdominal cavity is noticed through the X-ray diagnosis, then it indicates open tubes, where as if the dye is remaining in the uterus and does not indicate any spillage into the abdominal cavity indicates blocked tubes. Blocked fallopian tubes can result from scarring and adhesions due to infections such as chlamydia and gonorrhea that cause pelvic inflammatory disease (PID). In general, simple surgery can clear blockages in the fallopian tube. However, if the procedure is not successful, then in vitro fertilization is recommended procedure. IVF is a procedure in which oocytes are harvested from the ovaries and fertilized by spermatozoa in a dish containing a sterile nutrient solution. It is also possible that tubes get damag ed due to previous ectopic pregnancies. Even in such cases IVF is an option. Disorders of ovulation: Ovulation disorders include amenorrhea, lack of menstrual cycles, and oligomenorrhea, infrequent cycles. Two types of medication are used in case of ovulation disorders. Clomiphene citrate which is an anti-oestrogenic drug that stimulates the anterior pituitary to release FSH is the first set of treatment. If clomiphene treatment does not work, injections of FSH are given. These drugs are administered to stimulate ovulation and help in achieving pregnancy. Polycystic ovarian syndrome (PCOS): It is the most common cause of ovulation failure in women today. The ovaries typically contain numerous small immature follicles. PCOS can be easily detected through blood tests which measure hormone levels. It is more common in women under 30 years old and is due to an abnormal production of LH and FSH. The basic imbalance of these hormones in the women's body prevents the ovaries from releasing an egg each month. It also results in an abnormally high production of the male hormone testosterone by the ovaries. As a result of this there is increase of facial hairs. A combination of weight losing exercises and hormone treatments can help the patients with PCOS to conceive. Premature menopause: Menopause is a natural phenomenon occurring in women after a certain age. Premature excessive loss of oocytes results in premature menopause in approximately 2% of teenagers and women in their early 20s. In such cases, infertility can be overcome by IVF using donated eggs. Additionally the infertile recipient of the embryos takes oestrogen and progesterone to prepare her uterus for implantation of the embryo. Medical sciences has

The relationship between space and time in language Essay

The relationship between space and time in language - Essay Example We suggest that there is no direct interdependency between these terms, because they are defined by exact contextual environments and are clearly differentiated from one another in the natural environments. On the basis of modern studies and studies on temporal and spatial representations of previous years, we have examined linguistic basis to prove the fact of a co-existence of spatial and temporal relationships. Moreover, considerations from cognitive science, psycholinguistics and neurolinguistics are also relevant to further differentiation between spatial and temporal relationships. The spatial basis of temporal terms has been often supported by the majority of scientists and researchers (Cantor & Thomas, 2007; Clark, 1994; Levinson, 2003). This study opposes to the generally accepted methodological paradigm and it is claimed that there spatial/temporal terms chosen above are independent terms with complete semantics. Moreover, there is no need to investigate a temporal or spati al basis of these terms, because initially spatial domain is perceived as concrete and temporal domain is known as the abstract one. Therefore, we can suppose that â€Å"terms denoting space are concrete objects and the terms denoting time are abstract events† (Tenbrink, 2006). ... nt to investigate a possibility to identify definite limits between time and spatial relationships or it is relevant to talk about the existence and prevalence of spatiotemporal relationship. 2.0 Background Basing on the idea that human perception of time is related to space conceptualization is an unquestionable claim. It has been always underlined that time representation depends on space. In accordance with findings of psychological studies, it has been always claimed that it is natural of children to mix up spatial and temporal relationship (Clark, 1994). Clark (1994) was the first who claimed that â€Å"temporal language is based on spatial language and that English relational temporal prepositions are based on front and back† (Clark, 1994). Clark talked about â€Å"moving time† metaphor and â€Å"moving ego† metaphor and underlined that, for example, before is derived from in front of and after is derived from in back of, i.e. he correlates these two terms with â€Å"moving time† metaphor (Clark, 1994). Nevertheless, it is worth remembering that there is no one basic conceptual metaphor defining further metaphorical representations of a certain domain. A consistent basis of a metaphor has been often underlined by Lakoff and Johnson (1999). Therefore, it is necessary to underline that representations of concepts in metaphorical language is also possible outside this language, or in other words is possible in an independent manner. Still, there is a need to talk about the following peculiarities of metaphorical representations: metaphors are compatible with different domains though they do not have a scope covering different aspects of one domain and thus do not embrace the whole target concept. From another perspective, it is suggested by Habel & Eschenbach (1997)
