Differential diagnosis
Hematuria can be classified according to visibility, anatomical origin, and timing of blood during urination.In terms of the visibility, hematuria can be visible to the naked eye (termed "gross hematuria") and may appear red or brown (sometimes referred to as tea-colored), or it can be microscopic (i.e. not visible to the eye but detected with a microscope or laboratory test). Microscopic hematuria is present when there are three or more red blood cells per high power field. In terms of the anatomical origin, blood or red blood cells can enter and mix with urine at multiple anatomical sites within the urinary system, including the kidney, ureter, urinary bladder, and urethra, and in men, the prostate. Additionally, menstruation in women may cause the appearance of hematuria and may result in a positive urine dipstick test for hematuria. The causes corresponding to these anatomic locations can be divided into glomerular and non-glomerular causes, referring to the involvement of the glomerulus of the kidney. Non-glomerular causes can be further subdivided into upper urinary tract and lower urinary tract causes. In terms of the timing during urination, hematuria can be initial, terminal or total, meaning blood can appear in the urine at the onset, midstream, or later. If it appears soon after the onset of urination, a distal site is suggested. A longer delay suggests a more proximal lesion. In other words, shorter times suggest distal sites while longer times suggest proximal sites. Hematuria that occurs throughout urination suggests that bleeding is occurring above the level of the bladder.
Lifelong practice of safer sex reduces the likelihood that sexually transmitted diseases will impair fertility; obtaining prompt treatment for sexually transmitted diseases reduces the likelihood that such infections will do significant damage. Regular physical examinations (including pap smears) help detect early signs of infections or abnormalities. Not delaying parenthood. Fertility does not ultimately cease before menopause, but it starts declining after age 27 and drops at a somewhat greater rate after age 35. Women whose biological mothers had unusual or abnormal issues related to conceiving may be at particular risk for some conditions, such as premature menopause, that can be mitigated by not delaying parenthood. Egg freezing. A woman can freeze her eggs preserve her fertility. By using egg freezing while in the peak reproductive years, a womans oocytes are cryogenically frozen and ready for her use later in life, reducing her chances of female infertility. Treatment
There is no method to reverse advanced maternal age, but there are assisted reproductive technologies for many causes of infertility in pre-menopausal women, including:

Ovulation induction for anovulation
In vitro fertilization in for example tubal abnormalities

Epidemiology
Female infertility varies widely by geographic location around the world. In 2010, there was an estimated 48.5 million infertile couples worldwide, and from 1990 to 2010 there was little change in levels of infertility in most of the world. In 2010, the countries with the lowest rates of female infertility included the South American countries of Peru, Ecuador and Bolivia, as well as in Poland, Kenya, and Republic of Korea.
