Kettles are rated at 13A (3kW) but only load the circuit for a relatively short time, around 3-4minutes whereas ovens can potentially be switched on for hours and it is not good to load a ring circuit or radial circuit shared with lots of sockets in this way.f the oven is designed to be plugged in via a 13A socket then it will be supplied with a factory fitted flex and moulded 3 pin plug. If no flex is fitted ,likely to require hard wiring back to the CU, with local isolation, usually in adjacent cupboard or above worktop.
As a sex hormone testosterone is also responsible for most of the changes to the male sex organs. The most obvious of these is that the penis and testicles grow larger. Inside the scrotum, spermatogenic tissue begins to develop in the testicles. It is this tissue that produces sperm, enabling male fertility.
Â­From the outside, the male has two visible sex organs, the testes (or testicles) and penis. The testes are the primary male sexual organs in that they make sperm and produce testosterone. The sperm is the male sex cell, or gamete, and each testicle produces more than 4 million new sperm per hour [source: Angier ]. Testosterone is the hormone that causes male secondary sex characteristics such as facial and pubic hair, thickened vocal cords and developed muscles. The testes are housed outside of the main part of the male's body, in a sac called the scrotum. This location is important because in order for the sperm to develop properly, they must be kept at a temperature about two degrees cooler than normal body temperature.
