Male Reproductive System

Male Reproductive System
The male reproductive system is a series of organs located both outside of the body and within the pelvic region. The primary direct function of the male reproductive system is to provide the male gamete or spermatozoa for fertilization of the ovum, however it also serves as an endocrine gland .
The major reproductive organs of the male can be grouped into three categories. The first category is sperm production and storage. Production takes place in the testes, which are housed in the temperature regulating scrotum, immature sperm then travel to the epididymis for development and storage. The second category are the ejaculatory fluid producing glands which include the seminal vesicles, prostate, and the vas deferens. The final category are those used for copulation, and deposition of the spermatozoa (sperm) within the female, these include the penis, urethra, vas deferens, and Cowper's gland. An important sexual hormone of males is androgen, and particularly testosterone.
Testes are components of both the reproductive system (being gonads) and the endocrine system (being endocrine glands). The functions of the testes are: producing sperm (spermatozoa) & producing male sex hormones, (testosterone is the most common).
Sperm are haploid cells, (it’s 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell). These uniflagellar sperm cells are motile, have a limited life span (3 days), and cannot divide.  After fusion with egg cells during fertilization, a zygote is formed with the potential to develop into a new organism.
These spermatozoa are produced through spermatogenesis inside the male gonads (testicles) via meiotic division. They are carried out of the male body in a fluid known as semen
Prostate is an exocrine gland of the male reproductive system. The function of the prostate is to store and secrete a slightly alkaline (pH 7.29) fluid that usually constitutes 25-30% of the volume of the semen along with spermatozoa and seminal vesicle fluid. The alkalinity of semen helps neutralize the acidity of the vaginal tract, prolonging the lifespan of sperm. The prostate also contains some smooth muscles that help expel semen during ejaculation.

To Be Thought of Kindly

How Soccer Explains The World

Erik Voeten is delighted that researchers have picked up on the political implications of the sport:

My favorite example is a working paper by Edward Miguel, Sebastián Saiegh and Shanker Satyanath that uses evidence from professional soccer (football) matches to evaluate whether exposure to civil wars increases the propensity of young men to behave violently. They find that players from countries that have had more exposure to civil wars are much more likely to get yellow and red cards (cautions) than are players from countries that have had little or no recent exposure to civil wars. The findings are substantively strong and robust to a host of controls. The evidence comes from the main European football leagues, which are very cosmopolitan. This strikes me as an example of research that is both clever and important.

Lakota Nation files lawsuit against parties in sweat lodge incident

Lakota Nation files lawsuit against parties in sweat lodge incident

by Nina Rehfeld

SEDONA, AZ (November 12, 2009) - In the aftermath of the tragedy at Angel Valley Retreat Center, where an incompetently conducted “sweat lodge” held by Californian self-help guru James Arthur Ray killed three participants, political steps are being taken by several native people across the United States. While local Indians from Arizona are forming a Council for Indigenous Traditional Healing to reclaim native ceremonies, the Lakota tribe of North and South Dakota has filed a lawsuit against the United States, the state of Arizona, James Arthur Ray and the Angel Valley Retreat Center.

Ray had conducted a five-day “Spiritual Warrior” seminar at Angel Valley on the first weekend of October, during which his more than sixty participants had been fasting and wandering in the desert. He then assembled them in an incompetently constructed “sweat lodge” that, according to eye witnesses, was turned into a two-hour endurance competition and left three people dead and nineteen injured.

The Lakota Nation considers its sweat lodge ceremony, the Oinikaga, one of the seven sacred rites of the Lakota. “This is a way of life, not a religion”, said Sam Longblackcat, who introduced the lawsuit to the public at a press conference in Phoenix on November 2^nd.
