Aetiology of Congenital Absence of Vas Deferens: Genetic Study of Three Generations. (PDF, 4 MB) Human Reproduction, 1993. Factors contributing to the formation of antisperm antibodies in women are disturbance of normal immunoregulatory mechanisms, infection, violation of the integrity of the mucous membranes, rape and unprotected oral or anal sex. This allows for the diagnosis and treatment of conditions such as endometriosis with one procedure. Understanding male infertility: Sex Ed 101 To better understand infertility, here's a refresher course on the birds and the bees. (Anyone caught giggling will have to stay after class.) Sperm are made in the testicles.

The physician or WHNP may also suggest using a conception cap cervical cap, which the patient uses at home by placing the sperm inside the cap and putting the conception device on the cervix, or intrauterine insemination (IUI), in which the doctor or WHNP introduces sperm into the uterus during ovulation, via a catheter. Varicocele A varicocele is a swelling of the veins that drain the testicle, which can impact sperm quality. Affected individuals displayed more severe forms of infertility such as azoospermia and severe oligozoospermia.[27] Other causes[edit] Factors that can cause male as well as female infertility are: DNA damage DNA damage reduces fertility in female ovocytes, as caused by smoking,[28] other xenobiotic DNA damaging agents (such as radiation or chemotherapy)[29] or accumulation of the oxidative DNA damage 8-hydroxy-deoxyguanosine[30] DNA damage reduces fertility in male sperm, as caused by oxidative DNA damage,[31] smoking,[28] other xenobiotic DNA damaging agents (such as drugs or chemotherapy)[32] or other DNA damaging agents including reactive oxygen species, fever or high testicular temperature.[33] The damaged DNA related to infertility manifests itself by the increased susceptibility to denaturation inducible by heat or acid [34] or by the presence of double-strand breaks that can be detected by the TUNEL assay.[35] General factors Diabetes mellitus,[36][37] thyroid disorders,[38] undiagnosed and untreated coeliac disease,[39][40][41][42] adrenal disease[43] Hypothalamic-pituitary factors Hyperprolactinemia Hypopituitarism The presence of anti-thyroid antibodies is associated with an increased risk of unexplained subfertility with an odds ratio of 1. Isodicentric Y Chromosomes and Sex Disorders as Byproducts of Homologous Recombination that Maintains Palindromes. (PDF, 1 MB) Cell, 2009. Excess iron from multiple transfusions may get deposited in the pituitary gland and the testis, causing parenchymal damage and both pituitary and testicular insufficiency.

Approximately 4 million (9%) men aged 25–44 years reported that they or their partner had consulted a doctor for advice, testing, or treatment for infertility during their lifetime (4). Quantitative Evaluation of Spermatogenesis by Testicular Histology in Men with Congenital Absence of the Vas Deferens Undergoing Epididymal Sperm Aspiration. (PDF, 3 MB) Human Reproduction, 1990. Unexplained infertility in women or men may be managed with another year of unprotected intercourse, or may proceed to assisted reproductive technologies, such as intrauterine insemination or in vitro fertilization. However, varicoceles may lead to impaired testicular spermatogenesis and steroidogenesis, potentially due to an increased intratesticular temperature, reflux of toxic metabolites, and/or germ cell hypoxia as potential causes of these changes, and this appears to be progressive over time.

4) Uterine fibroids: Fibroids are very common (approximately 40% of women may have them) and the mere presence alone does not necessarily cause infertility. On the other hand, swollen, painful, or tender testicles may be a sign of an underlying issue, such as an infection, that can also impact sperm quality and male fertility.

In other cases, the cause is suspected to be immunological or genetic; it may be that each partner is independently fertile but the couple cannot conceive together without assistance. Lead, toxic fumes and exposure to pesticides are suspected contributors to infertility. However there is a minimal increased risk of de-novo chromosomal abnormalities in ICSI born babies [46,47] that necessitate counselling of the concerned couples.Table of contents Causes in men Causes in women Treatment Types Diagnosis Complications Outlook It may be that one partner cannot contribute to conception, or that a woman is unable to carry a pregnancy to full term. 42 However, none of these methods has been proven to increase pregnancy rates when used to predict timing of intercourse. Algorithm for infertility evaluation. (ART = assisted reproductive technology.) Lifestyle Factors Jump to section + All couples should be counseled to abstain from tobacco use, limit alcohol consumption, and aim for a body mass index less than 30 kg per m2 to improve their chances of natural conception or using assisted reproductive technology. 7K This app helped me conceive BeaMcCullough I have PCOS and was told I would never have kids. 2 or more - sperm concentration: 15 million spermatozoa per ml or more - total sperm number: 39 million spermatozoa per ejaculate or more - total motility: 40% or more motile or 32% or more with progressive motility - vitality: 58% or more live spermatozoa - sperm morphology (percentage of normal forms): 4% or more Basic Work-up for Infertility 13. Evidence of ovulation: 1.
