Weird news - Women sentenced to life in prison for cutting off husband's penis

Many years back, the word Bobbit came into significance (Wikipedia) when the wife cut off her husband's penis after claiming that he raped her. His penis was able to be re-attached and she was prosecuted for the major injury that she did on him. However, ever since, there have been other cases of such kinds of injuries happening once in a while. The nature of injury is so horrific that it is treated as a major injury, also because of the emotional impact it has on the person on whom such a injury has been committed.
This is not a normal injury, in the sense that it is not done normally by robbers and others, but is typically done by somebody who is intimate with the person whose penis has been cut off. It is quite normal that even in a husband and wife relationship, for the wife to cut the penis of such a person, means that their relationship is in a pretty bad state; and in such cases, it is quite normal for a criminal trial to happen. In the current case. the wife cut off the penis of the husband and threw it in the garbage dump, with the intention that the penis could be re-attached. In the trial, she was convicted of the crime and was sentenced for life (link to article):

Weird news - Man dies after his penis is injected with silicone

The length of the male sexual organ is something that drives a large amount of spam on the internet, and is actually a huge part of the self-esteem of a large number of males. People will do all kinds of treatments to increase the length of the male organ, and this is something that is fraught with danger. The penis, the male organ, is very sensitive, and is a center for pain as well, so any mis-step in this area can be very dangerous.
Taking medicines or any other medical treatment is a dangerous step if you are not sure of the credentials of the person who is doing it, such as this case where young male got his penis injected with a silicone implant, and it was this implant that was the cause of death (link to article):

Authorities have filed homicide charges against a woman after she allegedly administered a silicone injection into the penis of a 22-year-old man, who suffered a fatal blood clot.
The victim, who died in May, had been seeking a penis enhancement, authorities said today.
Kasia Rivera, 34, of East Orange, was arrested today on manslaughter charges and unauthorized practice of medicine in the death of Justin Street, the Essex County Prosecutor’s Office said.

Weird news - Woman cuts off the penis of attacker, takes it to the police

Attacks against women are one of the most problematic areas of law and order, especially in poorer countries. Most attacks that take place on a large scale also involve sexual attacks on the women (especially in situations where a community or members of one community attack one another). However, even otherwise, in poorer countries or poorer regions, the cause of law and order is never as serious as it would be in the more well off regions.
There are a much larger number of people in the same area, complaints made by women are not investigated with the same intensity and all this encourages such attacks. It is rare that women are able to get an upper hand; this incident shows a specific case where a lady managed to get the upper hand on the person who attacked her, and left him with a grievous wound. One does not encourage breaking of the law, but actions taken in self-defense are normally fine (link to article):

A 40-year-old Bangladeshi woman cut off a man's penis during an alleged attempted rape and took it to a police station as evidence, police in a remote part of Bangladesh said on Monday. The woman, a married mother of three, was attacked while she was sleeping in her shanty in Jhalakathi district, some 200 kilometres (120 miles) south of Dhaka, on Saturday night, officers said.
"As he tried to rape her, the lady cut his penis off with a knife. She then wrapped up the penis in a piece of polythene and brought it to the Jhalakathi police station as evidence of the crime," police chief Abul Khaer said.

A jilted lover turns violent, but cuts off own penis rather than hurt rival

Typically in cases where a person has been jilted, there is an emotional upheaval, which can take the shape of violent reactions. Lovers who have been jilted have been known to attack their loved ones, or the ones after whom their loved ones have gone. However, there are fewer cases where people attack themselves, causing harm to themselves; this is because of a strong feeling of despondency, hurt, and a feeling that there is nothing left in life. Sometimes however, they do things which seem totally weird to others, like this young Indonesian man who cut off his own penis and threw it down a well. He wanted to commit suicide, but was saved; however, since his cut-off penis could not be found, doctors could not reattach it (link to article):

Any hopes of reattaching the severed member were dashed after the 19-year-old threw the appendage into a well and it could not be found by residents of Bantasari village. Sugeng Budi Susanto, director of Cilacap General Hospital, said on Monday that it was extremely fortunate that medical personnel were able to save the life of the teenager, who was identified only by the initials AMD.
Though family members declined to comment, a source confirmed that AMD had cut of his penis after he discovered his girlfriend intended to marry another man. “The sliced-off penis has not been found,” the source said. “Allegedly, AMD threw it into the well with the intention of committing suicide because he thought nobody would be able to save his life.”
