Mass production of goods in places such as rapidly industrializing China has made what were once considered luxuries, such as vehicles and computers, inexpensive and thus accessible to many who were otherwise too poor to afford them.Even with new products, such as better seeds, or greater volumes of them, such as industrial production, the poor still require access to these products. Improving road and transportation infrastructure helps solve this major bottleneck. In Africa, it costs more to move fertilizer from an African seaport 100 kilometres (60 mi) inland than to ship it from the United States to Africa because of sparse, low-quality roads, leading to fertilizer costs two to six times the world average. Microfranchising models such as door-to-door distributors who earn commission-based income or Coca-Colas successful distribution system are used to disseminate basic needs to remote areas for below market prices. Health care and education
Nations do not necessarily need wealth to gain health. For example, Sri Lanka had a maternal mortality rate of 2% in the 1930s, higher than any nation today. It reduced it to 0.5–0.6% in the 1950s and to 0.6% today while spending less each year on maternal health because it learned what worked and what did not. Knowledge on the cost effectiveness of healthcare interventions can be elusive and educational measures have been made to disseminate what works, such as the Copenhagen Consensus.
In adults, the most common cause is epididymitis. Testicular torsion
Testicular torsion usually presents with an acute onset of diffuse testicular pain and tenderness  of less than 6 hrs of duration. There is often an absent or decreased cremasteric reflex, the testicle is elevated, and often is horizontal. It occurs annually in about 1 in 4,000 males before 25 years of age, is most frequent among adolescents (65% of cases presenting between 12 – 18 years of age), and is rare after 35 years of age. Because it can lead to necrosis within a few hours, it is considered a surgical emergency. Another version of this condition is a chronic illness called intermittent testicular torsion (ITT) which is characterized by recurrent rapid acute onset of pain in one testis which will temporarily assume a horizontal or elevated position in the scrotum similar to that of a full torsion followed by eventual spontaneous detortion and rapid solution of pain. Nausea or vomiting may also occur. Epididymitis and orchitis
Epididymitis occurs when there is inflammation of the epididymis (a curved structure at the back of the testicle). This condition usually presents with gradual onset of varying degrees of pain, and the scrotum may be red, warm and swollen. It is often accompanied by symptoms of a urinary tract infection, fever, and in over half of cases it presents in combination with orchitis. In those between the ages of 14 to 35 it is usually caused by either gonorrhea or chlamydia.
