Disorders of sexual differentiation result in infertility (eg, hermaphroditism, pseudohermaphroditism). It stimulates the ovaries to mature egg follicles. Diverse Spermatogenic Defects in Humans Caused by Y Chromosome Deletions Encompassing a Novel RNA-binding Protein Gene. (PDF, 2 MB) Human Reproduction, 1996. Mental stress: This may affect female ovulation and male sperm production and can lead to reduced sexual activity. Normal seminal fructose concentration is 120-450 mg/dL, with lower levels suggesting ejaculatory duct obstruction or absence of the seminal vesicles. Laparoscopic techniques have also been developed in the field of veterinary medicine.

However, if the woman has previously been pregnant, regardless of the outcome (which may have been a premature or full-term delivery, spontaneous abortion, induced abortion or ectopic pregnancy), and is now unable to conceive, it is considered secondary infertility. Patients with azoospermia or severe oligospermia are more likely to have a chromosomal abnormality (10-15%) than infertile men with sperm density within the reference range (1%). Lack of ovulation Patients with anovulation who did not ovulate after several cycles of CC at different doses of treatment are deemed clomiphene resistant.

In this case synthetic FSH by injection or Clomid (Clomiphene citrate) via a pill can be given to stimulate follicles to mature in the ovaries.

Varicocele: Surgically removing a varicose vein in the scrotum may help. GnRH analog ([GnRHa], leuprolide acetate, nafarelin acetate, goserelin acetate) causes down-regulation of the pituitary, inducing chemical menopause after injections of 3. Diverse Spermatogenic Defects in Humans Caused by Y Chromosome Deletions Encompassing a Novel RNA-binding Protein Gene. (PDF, 2 MB) Human Reproduction, 1996. GIFT (gamete intrafallopian tube transfer) and ZIFT (zygote intrafallopian transfer).  Like IVF, these procedures involve retrieving an egg, combining it with sperm in a lab, and then transferring it back to your body. These injections are taken nightly, typically for 5 – 10 days, and act directly on the cells of the ovary to stimulate egg development.

For example, a woman who has a 33-day cycle one month, a 31-day cycle the next, and a 35-day cycle after that, is probably having “normal” periods. Treatment of tubal obstruction generally requires referral for subspecialty care. Effects[edit] Psychological[edit] The consequences of infertility are manifold and can include societal repercussions and personal suffering. The main side effects are hot flushes, gastrointestinal events (nausea and vomiting), headache, back pain, and leg cramps. What Forms of Male Infertility are there left to Cure? (PDF, 2 MB) Human Reproduction, 1995. The severity usually depends on how near to the testicles the radiation was aimed. At the same time, the number of pregnancy losses and malformations in the foetus increase. A variety of disorders ranging from hormonal disturbances to physical problems, to psychological problems can cause male infertility.  Although many treatment options are now available, in many cases treatment will not work.  In many instances, male infertility is caused by testicular damage resulting in an inability of the testicle to produce sperm.  Once damaged, the testicle will not usually regain its sperm-making capabilities; this aspect of male infertility is analogous to menopause (though not natural like menopause) for women and cannot usually be treated.  Despite medicine�s limited ability to treat male infertility, many successful treatment options are available for its many causes.  Besides testicular damage, the main causes of male infertility are low sperm production and poor sperm quality.   The Causes of Male Infertility Male infertility has many causes--from hormonal imbalances, to physical problems, to psychological and/or behavioral problems.  Moreover, fertility reflects a man�s �overall� health.  Men who live a healthy lifestyle are more likely to produce healthy sperm.  The following list highlights some lifestyle choices that negatively impact male fertility--it is not all-inclusive: · Smoking--significantly decreases both sperm count and sperm cell motility. · Prolonged use of marijuana and other recreational drugs. · Chronic alcohol abuse. · Anabolic steroid use--causes testicular shrinkage and infertility. · Overly intense exercise--produces high levels of adrenal steroid hormones which cause a    testosterone deficiency resulting in infertility. · Inadequate vitamin C and Zinc in the diet. · Tight underwear--increases scrotal temperature which results in decreased sperm production. · Exposure to environmental hazards and toxins such as pesticides, lead, paint, radiation, radioactive   substances, mercury,  benzene, boron, and heavy metals · Malnutrition and anemia. · Excessive stress! During ejaculation, the ejaculate is propelled forward by the rhythmic contractions of the smooth muscle that surrounds the ducts and by the bulbourethral muscles and other pelvic muscles. Risk factors for both men and women are the same and these include age, stress, being underweight or overweight, diet, smoking, alcohol and drugs. However, hormones are not the main problem in 97% of infertile men. Recombination Between Palindromes P5 and P1 on the HUman Y Chromosome Causes Massive Deletions and Spermatogenic Failure. (PDF, 786 KB) The American Journal of Human Genetics, 2002. You take gonadotropins that trigger the development of more than one egg. Hormonal abnormalities can sometimes be treated with medicine or surgery. Contents Definition[edit] "Demographers tend to define infertility as childlessness in a population of women of reproductive age," whereas "the epidemiological definition refers to "trying for" or "time to" a pregnancy, generally in a population of women exposed to" a probability of conception.[8] Currently, female fertility normally peaks at age 24 and diminishes after 30, with pregnancy occurring rarely after age 50.[9] A female is most fertile within 24 hours of ovulation.[9] Male fertility peaks usually at age 25 and declines after age 40.[9] The time needed to pass (during which the couple tries to conceive) for that couple to be diagnosed with infertility differs between different jurisdictions. In ZIFT, your doctor places the fertilized eggs -- at this stage called zygotes -- into your fallopian tubes within 24 hours.
