Assisted Reproductive Technology: Using Ejaculated, Fresh, and Frozen-thawed Epididymal and Testicular Spermatozoa Gives Rise to Comparable Results after Intracytoplasmic Sperm Injection. (PDF, 5 MB) Fertility and Sterility, 1995. Problems with any of these steps may lead to infertility.Birth outcomes are compared after elective cryopreservation and delayed transfer versus fresh embryo transfer.Semen analysis The semen analysis is the cornerstone of the male infertility workup. Often, but not always, submucosal fibroids can cause heavy periods, or bleeding between periods. This may be used if IVF has not been effective, if there has been poor embryo growth rate, and if the woman is older. Microsurgery for Vasectomy Reversal and Vasoepididymostomy. (PDF, 13 MB) Urology, 1984. Chemotherapy: Some types may significantly reduce sperm count.

In patients with obstructive azoospermia and normal gonadotropin levels, sperm can be obtained through microsurgical epididymal sperm aspiration or testicular biopsy. [213] Fertilization of the oocytes is performed using IVF/intracytoplasmic sperm injection. Other causes of ovulation disorders include ovarian insufficiency and hypothalamic amenorrhea. Patients may have a normal palpable vas deferens bilaterally but show decreased ejaculate volume and hemospermia and may experience pain upon ejaculation. Other causes of ovulation disorders include ovarian insufficiency and hypothalamic amenorrhea.

Female and male factors are equally responsible for infertility, about 30% to 40% each, and in 20% of the cases, there is a combination of both. The vas deferens carries sperm from the epididymis to the ejaculatory duct and the urethra. Epididymal and Testicular Spermatozoa and Intracytoplasmic Sperm Injection. (PDF, 7 MB) Assisted Reproduction Reviews, 1996. Up to 2 percent of men are thought to have suboptimal sperm. Hence the ability to conceive a normal pregnancy decreases from when a woman is in her early 30s into her 40s. Treatment Treatment will depend on many factors, including the age of the person who wishes to conceive, how long the infertility has lasted, personal preferences, and their general state of health.

Blood tests that might be needed include day 3 follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), AMH, prolactin, testosterone (T), progesterone (P4), 17-hydroxyprogesterone (17-OHP), thyroxin (T4), thyroid stimulating hormone (TSH). Three regions have been described, called azoospermic factors a, b, and c (AZFa, AZFb, AZFc).[24] These deletions are observed in 3-19% of patients with idiopathic infertility and 6-14% of patients with oligospermia, although up to 7% of patients with other known causes of infertility may also be found to have a deletion. In contrast, anovulation usually manifests itself as irregularity of menstrual periods, that is, unpredictable variability of intervals, duration, or bleeding. Mannitol Induced Central Nervous System Toxicity in Renal Failure. (PDF, 4 MB) Investigative Urology, 1972. 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.

Compensatory and Obligatory Renal Growth in Rats. (PDF, 1 MB) American Journal of Physiology, 1974. Smoking: Smoking significantly increases the risk of infertility in both men and women, and it may undermine the effects of fertility treatment. Injuries to the bowel can cause a delayed peritonitis. In this article, learn about signs of infertility in both men and women, as well as when to see a doctor. London, United Kingdom: National Institute for Health and Clinical Excellence (NICE); February 2013:1–63. (Clinical guideline no. 8–16 One retrospective case-control study of 650 men with infertility and 698 control participants questioned the role of environmental risk; no association could be determined after assessing for multiple factors including shift work, stress, and pesticides. Similarly, there is no need for testing tubal patency for couples who will require IVF or ICSI procedure. Patients with less than of 14% normal forms had a substantially reduced success rate. For example, endometriosis can cause infertility with the growth of endometrial tissue in the Fallopian tubes or around the ovaries. Many couples with infertility issues go on to have successful pregnancies.
