Spermatogenesis

In modern society, different methods of birth control is being introduced. Contraception is more widely accepted in different countries and in different religions making it more easier for individuals to take care of children. However, there are still countries that cannot establish a social environment to make birth control methods such as male condoms and contraceptive pills work. One method of birth control is the use of male condoms. By putting it on the penis, it acts as a barrier because…

“Introduction to Beyond the Natural Body” written by Nelly Oudshoorn and “The egg and the Sperm” written by Emily both emphasize the idea of a woman’s body being examined through a social construct instead of a science classification. In the 1970’s, the female body was explained in terms of how the male body was perceived, for example: in texts written by the Ancient Greeks would refer the female genitals, the ovaries as the “female testicle”, as it used the male organs to lead every description…

5. Dwivedi, et al., (2008) described that the Synthesis of 11-substituted estradiol derivatives (12–17) has been approved out by the Grignard reaction with alkyl, allyl, and benzyl halides on 17b-hydroxy-3-methoxy-11-oxo-estra-1,3,5(10),8(9)-tetraene (10). The novel compounds (10 and 12–17) were appraised for their preliminary post-coital contraceptive (anti-implantation) activity in Sprague–Dawley rats. The tested compounds were managed orally and exhibited noteworthy anti-implantation activity…

prescription rates. Along with this trend comes an increase in the data surrounding TRT. This influx adds to the large scale, randomized studies conducted on the use of TRT in hypogonadal men. TRT is widely accepted to provide relief from retarded spermatogenesis, low sex function, depression, and bone fiber deterioration in aging men. While testosterone is associated with facial hair, libido, and increased muscle growth it is also important to consider testosterones hematopoietic effects. These…

Sport related injuries in children and young adults (ages 5-24) account for over 2.6 million visits to the emergency room each year in the United States alone (Goldberg, Moroz, Smith, Ganley, 2007, pg. 265). The increase in sport participation among junior high, high school and college sports, which has led to the rise in injuries, strains for improved rehabilitation and better injury prevention. As the sport world ever changes and the societal demand for more efficient athletes becomes…

However, this is an important social issue that should receive more awareness because this means that there are less people procreating, which may lead to a smaller global population. In this paper I will be addressing who is affected by infertility, the causes as well as risks and treatments. Office of Women’s Health (OWH), (2012) states that according to the Center for Disease Control (CDC), about 6 million women, ranging in age from 15-44 have difficulty conceiving. OWH states that both men…

via the portal system to the pituitary to stimulate the release of gonadotrophins from the adenohypophysis. In men LH stimulates the Leydig cells present in the testes to secrete testosterone whilst FSH binds to the Sertoli cells and promotes spermatogenesis. In women the LH leads to ovulation whilst FSH stimulates the Granulosa cells and initiates follicular growth. It is known (2) that the GnRH neurones migrate from the olfactory placode along the vomeronasal nerves. The factors that control…

or modified at any desired location. Successful experimentation on mice has demonstrated that this method can be used to restore fertility by transplanting spermatogenical stem cells from another organism into the testes of a mouse, restoring spermatogenesis and fertility. Genetic engineering in this way can be used to change physical appearance, improve metabolism, improve physical capabilities and mental faculties, such as intelligence, and even extending human lifespan. Theoretically, since…

Steroids are performing enhancing drugs that have a negative connotation associated with them. They are known for preventing athletes from competing in various competitions, ending athlete’s careers, and have resulted in numerous deaths. When used incorrectly steroids can be harmful to an athlete’s body and can effect their mindset negatively. However, when used properly and in a controlled manner steroids can be exceedingly beneficial for all athletes. If steroids became legalized, sports would…
