The histology (tissue structure) of the urethra makes it an easier target for infection than the squamous epithelium of the external penis. For this reason, contact with an STD is likely to infect the urethra.
Disease ---> infection
The urethra is an open entryway to bacteria.
Male: Vas deferens Female: oviduct or fallopian tube
The three regions of the male urethra are:Prostatic urethraMembranous urethraspongy urethra
The assists in emptying the male urethra
It is much easier for a female to catch a kidney infection. The human body has a host of bactiria, yeast and fungus on it. Just the difference in anatomy makes it more common. In order for a male to get a kidney infection(or bladder infection). Usually he will contract a urinary tract infection by bactaria entering the urethra. The mainreason it is harder for men is the size of the urethra in a male is narrower and much harder for the bactaria to travel thru compaired to a female.Kidney disease does not discriminate against either sex. It can affect male of female. It is true that females due get infections easier.
the membranous part of urethra
male urethra is long and female urethra is short
urethra
The urethra is the passageway for semen as it leaves the male's body. In the male, the urethra carries semen and urine, while in the female the urethra only carries semen.
If the male has an STD, it is definitely possible to become infected if you swallow his semen. Any contact with bodily fluids can result in infection.
The length of female urethra is very much short as compared to male urethra. So infection can be more easily introduced from out side, to urinary bladder. The source of infection is very close, that is faecal matter. You can have millions of bacteria in very small amount of faecal matter.
Samples are collected from one or more of these infection sites: cervix, vagina, or urethra in a female, urethra in a male, or the throat or rectum. But chlamydia cultures are uncommon these days. Usually other types of testing are used for chlamydia.
