How are genital infections different in men and women? Infection is infection regardless of gender.
There is no difference really, other from the body part it affects and the actual name of the infection.
For instance: Bacterial vaginosis is familiar in women affecting the vagina causing symptoms, while, Balanitis is a penile condition which also causes symptoms, but familiar in men affecting the penis.
How similar are male and female genital infections? Both cause symptoms, and both require treatment.
so very similar in that respect.
Of course, the approach to clear an infection could dramatically alter in regards to medication, due to the severity or stage the infection is at.
If the vagina is infected the matter becomes a woman's thing, and if the penis is infected the matter then becomes a man thing, nevertheless, there are always going to be SYMPTOMS, so in my opinion that makes whatever the infection a matter for a doctor - making male and female genital infections very similar indeed.
Balanitis means inflammation of the glans (the rounded head) of the penis.
Posthitis is inflammation of the foreskin.
Foreskin is the loose skin that covers the head of the penis if the man has not been circumcised.
If the two, glans and foreskin are inflamed, it is called balanoposthitis.
Symptoms

• Red glans
• Inflammation of the glans
• Soreness of the glans
• Clotted discharge under the foreskin
• Itchiness
• Bad odour
• Irritation of the glans
• Phimosis - the foreskin is tight and hard to pull back
• Painful urination

Bacterial Vaginosis also known as BV.
Vaginal bacteriosis is one of the commonest causes of vaginal infection for women of childbearing age.
Although a condition that often develops after having sex with a new partner, bacterial vaginosis is not considered a sexually transmitted infection.
Symptoms

• Watery vaginal discharge
• Grey or white discharge
• Unpleasant fishy smell
• Uncommon symptoms
• Burning sensation when urinating
• Vaginal itch

Gonorrhea in men: This is a sexually transmitted disease that has varied symptoms depending on which part of the body has been infected.
It can take up to a month after infection actually happened before symptoms start making themselves known.
Early symptoms

• Penis discomfort
• Thick white, yellow or green discharge from the tip of the penis
• Pain or burning when urinating

If gonorrhea spreads as a result of ignoring the problem and getting no treatment, it can reach body parts such as the glands near the urethra, the prostate, seminal vesicles, testes and bladder, which then could lead to:

• Rectal or urethral abscesses
• Swelling
• Sore testicles
• Hard to urinate
• Gonorrhea of the rectum
• Anal itch
• Discharge from the anus
• Rectal pain, especially when passing stools

Gonorrhea in women

• Burning
• Frequent urination
• Yellowish vaginal discharge
• Redness
• Swelling
• Vaginal itching

Gonorrhea can lead to a severe pelvic infection with inflammation of the fallopian tubes and ovaries if you don't get medical help.
Yeast infections are something people believe is a woman's condition...
wrong! Thats right, men also get yeast infections.
Yeast vaginitis is a vaginal infection caused by a fungus known as Candida.
It is characterized by

• Vaginal itch
• Soreness
• Painful sex
• Painful urination
• Discharge

Syphillis comes in four stages, each with a different set of symptoms, ranging from mild to severe.
Syphilis is a slowly progressing disease.
Primary stage of syphilis: One or more painless sores/ulcers (chancres) develop at the site where the bacteria first entered the body.
Chancres may be hard to spot and are highly infectious.
Typical places to see them are:

• On the vulva or cervix
• On the penis
• Anus and mouth

Secondary stage syphilis symptoms often include:

• Flu-like feeling, fatigue and loss of appetite along with swollen glands
• Rash covering the whole body or coming in patches.
  
• Flat, warty-looking growths on the vulva and around the anus
• White patches on the tongue or roof of the mouth
• Hair loss

Latent and tertiary stages of syphilis usually happens when treatment was left too late in the first two stages.
The patient will now no longer suffer many symptoms of the earlier stages, but their infection can still be diagnosed with a blood test.
Symptomatic late syphilis, also known as the tertiary stage is now the end result.
This stage is serious, possibly affecting the heart and nervous system.
