An abnormal semen analysis warrants a further evaluation usually by a reproductive urologist. First Fallopian Tube-Ovary Transplant Carried Out. (PDF, 2 MB) Welcome Trends in Ob/Gyn, 1985. 5°F above the basal level) induced by the early secretion of progesterone.

Hormonal Problems A small percentage of male infertility is caused by hormonal problems.  The hypothalamus-pituitary endocrine system regulates the chain of hormonal events that enables testes to produce and effectively disseminate sperm.  Several things can go wrong with the hypothalamus-pituitary endocrine system: · The brain can fail to release gonadotrophic-releasing hormone (GnRH) properly.  GnRH stimulates   the hormonal pathway that causes testosterone synthesis and sperm production.  A disruption in   GnRH release leads to a lack of testosterone and a cessation in sperm production. · The pituitary can fail to produce enough lutenizing hormone (LH) and follicle stimulating hormone   (FSH) to stimulate the testes and testosterone/sperm production.  LH and FSH are intermediates   in the hormonal pathway responsible for testosterone and sperm production. · The testes� Leydig cells may not produce testosterone in response to LH stimulation. · A male may produce other hormones and chemical compounds which interfere with the   sex-hormone balance. If the correction is not done, it may be harder for the sperm to get to the female's cervix.

Further backup measures are sufficient thrombosis prophylaxis with heparin and the support of the renal function. CASA measures the following parameters: Curvilinear velocity – The average distance per unit time between successive sperm positions) Straight-line velocity – The speed of forward direction Linearity – The straight-line velocity divided by the curvilinear velocity In addition, the program measures the average path velocity, the amplitude of lateral head displacement, and the flagellar beat frequency, and it is used to evaluate for evidence of hyperactivation. When Predictions Don’t Predict. (PDF, 549 KB) The Australian and New Zealand Journal of Obstetrics and Gynaecology, 1991. Requirements for Male Fertility (Continued) The ability to transmit the spermatozoa to the female vagina is also important. Cystic fibrosis CF is the most common genetic disorder in whites. 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!

If there is a history of recurrent miscarriages (2 or more) a lupus anticoagulant (LAC) and anti-cardiolipin antibody (ACL) are often done, as well as other tests. 24 Other tests of ovarian reserve, such as the clomiphene (Clomid) challenge test, antral follicle count, and antimüllerian hormone level, are also generally performed to predict response to ovarian stimulation with exogenous gonadotropins and assisted reproductive technology. Do you have pain with menstrual periods or intercourse? This technique involves an injection of a single healthy sperm directly injected into mature egg. Ovulation induction in polycystic ovary syndrome [published corrections appear in J Obstet Gynaecol Can. Possible problems could be that the egg is not released at the optimum time for fertilization, that it may not enter the fallopian tube, sperm may not be able to reach the egg, fertilization may fail to occur, transport of the zygote may be disturbed, or implantation fails. 4) Uterine fibroids: Fibroids are very common (approximately 40% of women may have them) and the mere presence alone does not necessarily cause infertility. 4) In Vitro Fertilization (IVF): In vitro means “outside the body.” IVF is a process whereby eggs are collected and then fertilized by sperm outside the body, in an embryology laboratory. For example, endometriosis can cause infertility with the growth of endometrial tissue in the Fallopian tubes or around the ovaries. Many health conditions can make it hard to get pregnant. Women in group II include those with polycystic ovary syndrome and hyperprolactinemia. The only disadvantage with BBT is that in many instances, the shift does not occur in a clear way, and the patient misses the time of ovulation.
