Male reproductive system

penile-vaginal sex is the only action that is marked as a “homerun” on the scoreboard. The standard is that humanity cannot continue to exist without the union of sperm, from a man’s penis, and egg, from a woman’s ovaries. Therefore, the penetration of the male sex organ into…

The sex chromosome determines whether a zygote will be male or female. Females have XX sex chromosomes and males have XY chromosomes. One chromosome comes each comes from the gametes of the parents. Each egg has an X chromosome and “if the sperm contains a Y chromosome, the match with the female chromosome will be XY, and the child will be genetically male,” (Ginsberg, Nackerud & Larrison, 2004, p. 198). On the other hand if the chromosomes from each parent…

the rise of how closely related gender, and sex are and how fragile this topic can be. First let me contrast the terms sex and gender. Sex refers to the biological differences involving females, and males for example their chromosomes (female XX male XY), hormones (estrogen, testosterone), and reproductive organs (ovaries, testes). Gender involves the cultural contrasts expected from society, and culture of women, and men according to their sex. In essence a person’s sex does not change from…

time they begin to settle down. This begins the hot debate of who should be using birth control, male or female. Male birth control has been a wide controversy for many who worry that males will become impotent with extended use of birth control. Many of the so-called facts about male birth control have been tested and proven wrong. The idea of long term negative affects on the male reproductive system has been tested and proven wrong, and amongst this it has actually shown to be more…

taken from male birds at the beginning of the experiment from all birds via blood samples. At the height of incubation, which we expect to be early to mid May, all birds in the prolactin implantation group will have their blood samples taken to compare hormone levels in males verses females. This will be used for comparison at the end of the experiment. Out of the three groups we are using, only the two experimental gorups will be given prolactin implants and within these groups, only the males…

If these theories are correct and male promiscuity is an innate behavior within male genetics and physiology, then it would be expected that these results could be replicated and that it is possible to record such behaviors in humans. A study conducted by Gowaty, Kim and Anderson, (2012) attempted to replicate…

I want to argue against the gender essentialist claim about “women being not able to make the clearest or the most logical decision”. The phrase has been used multiple of times to block women from climbing up the ladder to the most prestigious positions such as managerial positions in companies and representation in the community/party; thereby, such claim created the notorious glass ceiling for women, especially in those higher positions. As of 2014, only 26 women lead the companies listed in…

Heteronormativity is the belief that people can be categorised into definite and interdependant genders, women and male. It postulates that heterosexuality is the only sexual orientation. This ideology states that sexual relations between these two genders are most suitable within opposite sexes. These views are based in relation to biological sex, gender indentity, sexuality and gender roles. Gender refers to the socially constructed roles, behaviours, actvivities and attributes that a given…

testosterone and estradiol have a carbon skeleton with four fused rings and what makes them different is the functional groups attached to the rings. Androgens, such as testosterone, are a major class of steroid hormones accountable for the creation of male sex characteristics. For instance, through the substitution of an acid group for the hydroxyl group, known as esterification of testosterone, the water solubility of the molecule is lowered and its lipid solubility enlarged, permitting a…

tough, she did not have a female reproductive system. In Thomas Beatie's case, he was born a female but never felt like one. When he grew older he decided to change his gender to male, making him a transsexual. In David Reimer’s case, he was born a guy but was raised as a girl due to getting his penis burned. But never in his life had he felt like a female because he knew something was different with him. When he grew older he found out that he was born a male. And when he was old enough, he…
