Essay About Semen Sex

Review of Literature 2.1 Semen Sexing In order to meet the Indian food demand associated with this population growth, it will be necessary to utilise modern biotechnologies to promote the sustainable production of animals and agricultural resources. Production of pre-sexed livestock by semen sexing, when combined with other assisted reproductive biotechnologies like artificial insemination and IVF offers a promising breeding strategy to help meet the increased nutritional demand for food. Sexed semen is semen that has been sorted by its X and Y chromosomes carrying sperm and allows a producer to limit its offspring to a single sex as opposed to the near 50/50 natural selection. Sexed semen can achieve 90% accuracy of a desired sex, suggesting …show more content…

But regardless of which pre-fertilisation technique is used to influence the sex ratio of offspring it must fulfil certain criteria. First of all it must achieve a complete separation of the X and Y bearing sperm in sufficient quantities. Secondly sperm must be viable after separation and capable of fertilising. Sex pre-selection methods can be divided into two general groups which either separate spermatozoa on the basis of subtle physical or kinetic features or those which rely on distinctive nuclear characteristics unique either to X or Y chromosome bearing sperm. Several techniques based on principals such as size and shape, velocity, electric surface charge, surface antigens have been developed and tested for separation of X and Y-chromosome bearing spermatozoa. According to scientific studies neither of these methods was able to produce significant separation of fertile sperm populations, or was not repeatable. Only sex selection of spermatozoa by chromatin differences (cell sorting by flow cytometry) has demonstrated a significant enrichment of the X bearing

    Eric has a possibility of being sterile because of the hyposecretion of T4 and T3, which can cause sterility (Marieb & Hoehn, 2013, p.607). Eric might also be sterile because of his low testosterone levels. This causes semen volume to decrease, and it can impair erection and ejaculation, leading to sterility (Marieb & Hoehn, 2013, p.1034). 2.

    No wildtype (Fog-2/normal) was identified in F2 generation. Evidence concludes that, the mutant allele is sex-linked recessive. The fall back to the experiment was we had a high ratio of hermaphrodites in F1 and F2 generations. The explanation for this occurrence is the hermaphrodites self-fertilized. This due to a low number of males breeding with the females or accidentally capturing a self-fertilized hermaphrodite.

    The physical effects on selected children are unknown, and can’t be researched without major ethical dilemmas such as human testing and the disposal of fertilized eggs.

    The developing gonad, with its affected protoplasm, develops into a new individual of the F2 generation (i.e., offspring), carrying changed soma. New metabolic substances in the F1 organism are passed on to the organism of the newly developing individual, which consequently shows the same variation as the parent, albeit removed from the inducing environment in question. These substances might be of such a nature as to stimulate the formation of antibodies, thus causing a reaction in a later generation.

    Sex has a history of being defined somewhat narrowly, centering on traditional cultural and religious norms and heterosexual practices. “Some definitions imply that sex can only happen if someone is trying to get pregnant. Other definitions imply that penetration must be involved for sex to have occurred(alice 5).” Although this straightforward definition might work in some cases, it clearly doesn’t include all sexual activities that we count as sex, not everyone can spot their sexual experiences in these definitions, so why not alter or expand definitions to reflect lived experiences?

    Understanding gender and sexuality as socially constructed categories is important because it helps people understand a certain group. Gender and sexuality is expressed in many categories and people must be careful not to mix people in the wrong category. Simply because one expresses their sexuality different from another person does not mean they should be bashed or treated differently. Sometimes it does not matter what you identify as, who you identify with, people will always judge you, so its best people just do what they want. Putting gender in a category helps others not stereotype them as something they are not.

    The purpose of the Female Reproductive System The Female Reproductive System has several functions and plays a major role in a woman’s body. The ovaries produce the female eggs which are called the Ova or Oocytes. The Oocytes are transported to the Fallopian Tube which fertilization by sperm can occur. The fertilized egg then moves to the uterus, which the uterline lining has thickened in response to the normal hormones of the reproductive cycle.

    Sexual reproduction is most common type of reproduction among the plants and animals. They are of following types; 1) Syngamy: The fusion of gametes takes place completely, if male and female gametes are produced by same cell or organism and both gametes fuse together to form a zygote, this is called as Autogamy, paramecium is its example. Another is Anisogamy in which some organisms produce two types of gametes. Both types of gametes differ from each other in their shape and size and are known as an isogametes or heterogametes. Male gametes are motile and small in size and are known as micro gametes.
