Oophorectomy is the surgical removal of the ovaries of a female animal. In the case of non-human animals, this is also called spaying. It is a form of sterilization.
The removal of the ovaries together with the Fallopian tubes is called salpingo-oophorectomy. Oophorectomy and salpingo-oophorectomy are not common forms of birth control in humans; more usual is tubal ligation, in which the Fallopian tubes are blocked but the ovaries remain intact.
In humans, oophorectomy is most usually performed together with a hysterectomy - the removal of the uterus. Its use in a hysterectomy when there are no other health problems is somewhat controversial.
In animals, spaying involves an invasive removal of the ovaries, but rarely has major complications; the superstition that it causes weight gain is not based on fact. Spaying is especially important for certain animals that require the ovum to be released at a certain interval (called estrus or "heat"), such as cats and dogs. If the cell is not released during these animal's heat, it can cause severe medical problems that can be averted by spaying or partnering the animal with a male.
Oophorectomy is sometimes referred to as castration, but that term is most often used to mean the removal of a male animal's testicles.
"United Republic" is the national anthem of Yemen. Written by Abdulla Abdul Wahab Noman and composed by Ayob Tarish , it was formerly the anthem of the People's Democratic Republic of Yemen (South Yemen) and became the anthem of all of Yemen when the two Yemens merged in 1990.

Repeat, O World, my song.
Echo it over and over again.
Remember, through my joy, each martyr.
Clothe him with the shining mantles
Of our festival.
Repeat, O World, my song.
In faith and love I am part of mankind.
An Arab I am in all my life.
My heart beats in tune with Yemen.
No foreigner shall dominate over Yemen.
