What Are The Causes Of Male Infertility, And Interactive Problems?

Factors that contribute to infertility in males are:
--- Congenital Factors: Congenital factors include maternal history of DES ingestion during pregnancy and absence of the as deferens or the testes.

--- Ejaculation Problems: Ejaculation problems include retrograde ejaculation associated with diabetes, nerve damage, medications, or surgical trauma.

--- Sperm Abnormalities: Sperm abnormalities include inadequate sperm production or maturation, inadequate motility, blockage of sperm along the male reproductive tract, and an inability to deposit sperm in the vagina.

--- Testicular abnormality: Testicular abnormalities include those due to illness (for example, orchitis associated with mumps after puberty), cryptorchidism, trauma, or irradiation.

--- Coital difficulties: Coital difficulties may occur owing to obesity or spinal nerve damage.

--- Drugs: (such as methotrexate, amebicides, sex hormones, and nitrofurantoin) may interfere with spermatogenesis.

--- Other Factors: that interfere with sperm or semen production include infections (such as sexually transmitted diseases), stress, inadequate nutrition, excessive alcohol intake, and nicotine.

Interactive Problems
Interactive problems resulting from causes specific to each couple include:
--- Insufficient frequency of sexual inter course.
--- Poor timing of inter course.
--- Development of antibodies against a partner's sperm.
--- Use of potentially spermicidal lubricants, such as petroleum jelly and some water soluble lubricants.
--- Inability of the sperm to penetrate the egg.
