Spermatogenesis

increase, blood coagulation decrease (it causes the often nosebleeds and bleeding nonhealing wounds), sebaceous glands hyperfunction and progressive acne. Some patients suffer from headaches and sexual super stimulation. There are possible the spermatogenesis delays, i.e. testicles start producing less testosterone when an athlete has been taking very big doses for pretty long time. Nandrolone Deca, as almost all steroids, leads to the delay of gonadotrophin outflow from hypophysis. By…

when the FTO gene is overexpressed or in an abundance amount, then m6a levels would be decreased and therefore less methylation or in other words, more expression of the fat-mass and obesity. The function of the ALKBH5 is a protein linked to spermatogenesis and FTO, which acts as a m6a demethylase or "eraser". As evident, the a decreased level of FTO causes an increase level of m6a tags that promote methylation; due to this, it can be inferred that an increased level in ALKBH5, would lead to…

Cryopreserved stallion semen used for Artificial Insemination (AI) is on the rise due to the amount of breed registries allowing this method to be incorporated into their breeding programs. The pregnancy rates using cryopreserved semen are currently still low due to the lack of proficiency in the post-thaw motility. When comparing the use of frozen semen to fresh semen for AI in mares the success rate is <75% of what is achieved by using fresh semen (6). The cryopreservation success rate is…

The cane toad reproductive system especially of male consists of the fat bodies and this cannot be found in a reproductive system of a common brushtail possum. The process of how sperm travels is also different between the two animals. In a common brushtail possum, the sperm travels through the vasa deferentia, which transports the sperm from the epididymis to the urethra (Venugopal, 2016. pg 3.5). While in a cane toad the vasa efferentia helps carry the sperm from the testes to the kidney and…

Lead (atomic symbol Pb) is a well-known substance found in many man made materials. It is used in building construction and is found in items such as batteries, bullets, and paint. It is also found in nature in the soil, dust, and in drinking water (1). The presence of lead in drinking water is a major public health concern; this substance is toxic if ingested. In pregnant mammals, lead poisoning will not only affect the mother, but will also transfer across the placenta and will harm the fetus…

of support. These cells control the environment by removing wastes, providing nutrients, and providing antibody protection as well as regulating sperm production. Interstitial cells outside of the tubules secrete testosterone and stimulates spermatogenesis. Describe the structure and function of the epididymis, ductus (vas) deferens, ejaculatory duct and urethra. Relate the location and storage of sperm to a vasectomy.…

The two ways cell division can occur are through mitosis and meiosis. In mitosis, a cell produces two clones of itself, each with the same number of chromosomes. In meiosis, a cell will produce four cells called gametes through the process of spermatogenesis and oogenesis. Gametes are most commonly known as sperm cells in males and egg cell in females. Unlike mitosis, the gametes that meiosis produces are not clones of the original cell as each gamete has exactly had as many chromosomes of the…

Effects of Social Media on Today 's Society Today technology is changing the world in many ways it seems we aren’t able to control. Social media and cell phones are beginning to change our lives and the way we live daily. We tend to pay more attention to our phones than we do anything else around us. Some don’t tend to realize the risks they are taking. People don’t communicate as much in person as they used too. How many accidents occur from people being on their phones while driving? Are…

Busulfan is anticancer drug caused variety of adverse effects for cancer patients. It’s used to treatment of chronic leukaemia but it could cause damage to the male reproductive system as one of its adverse effects. This study aim to investigate the effect of L-carnitine and L-arginine on semen quality, oxidative stress parameters, caspase3 and testes cell energy after busulfan treatment. Materials and Methods: thirty-two adult male rats were divided into four groups. Group I (Control)…

1. Detail the first part of the digestive system from the mouth to the esophagus including the structure and functions of each part. The first part of the digestive system is comprised of the mouth, the pharynx and the esophagus. The mouth is an oral cavity that starts the process of mechanical and chemical digestions when food is received. The mouth is bounded by the cheeks and lips. The mouth contains a soft and hard palate, salivary glands, teeth (crown and dentin) and the tongue (covered…
