Female Primates have distinctive features, which differentiate them from other mammals. First off they have fewer offspring than the normal mammals and each birth is more spaced out over time and can be long as years in between births. Primates mother take tons on care of their young, they provide them food and teach them social behaviors and social roles. Primates are identified into six different residence patterns. First there is the One-male and multi-female, this group has one…

Pthirus pubis, also known as pubic lice or crab louse, is an ectoparasite, which is strictly host specific to humans. Pubic lice have three stages: egg, nymph, and adult (CDC, 2017). Pubic lice targets coarse hair at its base and normally remain on its host until it is removed, controlled, or treated. Initially, the female will lay two to three eggs, also known as nits, over the course of twenty-four hours (CDC, 2017). The nits have a whitish in color and have an oval-like structure, with an…

Evolutionary considerations of mate choice date back to Darwin (1871), when he proposed a mechanism know as sexual selection. This proposed mechanism can explain characteristics like plumage of peacocks, fight in elephant seals over females mate, longer neck in giraffes to exhibit dominance in females and so on. These characteristics contradict natural selection (survival of fittest). Sexual selection can be divided into two processes, namely intersexual and intrasexual selection (Buss, 1986).…

Discussion: After analyzing the data from the experiment, we found that the difference between the groups with one male, and those with two males, was not statistically significant as our p-value was well above the accepted value of 0.05. The mean difference in latency to copulation for the two groups was only 1.4 seconds. As seen in the results, the presence of male-male competition does not significantly impact latency to copulation in the Tenebrio molitor species. Our experiment focused on…

The film In the Womb gives the audience much perspective and insight into the complicated process of pregnancy. As defined by the textbook, “vaginal intercourse is the insertion of the penis into the vagina,” which is the only kind of sexual activity that can lead to conception. It is astounding that upon ejaculation, 500 million of the smallest type of human cell travel to the fallopian tubes within the female, but the body ensures that only one sperm can become attached. This is provided that…

Pauline – Great power point. The more I thought of your question on having a diagnosis of endometriosis and infertility would you be willing to have a hysterectomy, to prevent the possibility of having ovarian cancer, and help in reducing the symptoms of endometriosis the harder I found it answer it. I thought maybe as a man I might not know exactly how it would feel but then again a woman wouldn’t either if she hadn’t experienced this. As a nurse and as a single father to my 20 year old…

Art Therapy as a Healing Tool for Sub-fertile Women, an 11-page summary of multiple studies completed by the Hamilton Health Science Centre for Reproductive Care, is about the effects of art therapy on infertile women. This study used questionnaires and art therapy to help relieve participants’ anxiety and depression. The participants in the experiment were twenty-one women with a mean age of 35.7 and a duration of sub-fertility of 64 months. The women were organized into groups of three…

The most important aspect of olive baboons mating systems is their involvement in consortships. Male baboons will follow female baboons around, guarding them from other males and participating in frequent grooming and sexual mountings (Bercovitch 1983). Due to the fact that other male olive baboons often harass couples in consortship, often there is a large male turnover during a single female fertility period—thus their polyandrous behavior. Female baboons often consort with an average of…

15. A 35-year-old female present at your clinic to discuss birth control. She has 2 children with her husband and they are in agreement that their family is complete. You discussed with her different options. Which statement is true regarding Intrauterine Devices (IUD)? A. Success rate of the IUD is slightly lower than oral contraceptive pills B. Failure rate of the IUD ranges from 0.2-0.9% within the first year of insertion C. Prophylactic antibiotic should be routinely prescribed before IUD…
