  • The Endocrine Society 3 defines hypogonadism in men as a clinical syndrome that results from failure of the testes to produce adequate levels of testosterone and a normal number of sperm due to a disruption of the hypothalamic-pituitary-gonadal (HPG) axis. (ndnr.com)
  • Typically, follicle-stimulating hormone (FSH) levels are low (hypogonadotropic) commensurate with inadequate stimulation of the testes to produce sperm. (wikipedia.org)

  • defects
  • Problems delivering the sperm into the woman's body can include swelling and physical trauma, retrograde ejaculation where the sperm are directed into the bladder rather than out of the body, or blockages or sperm duct defects. (sharecare.com)
  • The frequency with which sperm defects contribute to recurrent pregnancy loss has not been established and the relationship between standard semen parameters and recurrent miscarriage has been a controversial subject. (punchng.com)
  • Reproductive endocrinologists treat men having hypogonadism due to defects in the HPG axis with injectable medications such as recombinant FSH, human chorionic gonadotropin, human menopausal gonadotropin hormone, or GnRH. (ndnr.com)
  • In other words, older sperm are less likely to result in a successful pregnancy and, moreover, the cumulative fragmentation of sperm DNA over time increases the likelihood that a small fraction of men will pass on achondroplasia and transmit multiple genetic and chromosomal defects. (wikipedia.org)
  • counts
  • A 2017 review and meta-analysis found sperm counts among Western men (i.e. men in Australia, Europe, New Zealand, and North America) declined 50-60% between 1973 and 2011, with an average decline of 1.4% per year. (wikipedia.org)
  • hypogonadism
  • In men, CD can reduce semen quality and cause immature secondary sex characteristics, hypogonadism and hyperprolactinaemia, which causes impotence and loss of libido. (wikipedia.org)
  • Of note,hypogonadism is fairly common in the middle-aged and older male population and is strongly associated with various chronic conditions such as type 2 diabetes mellitus, metabolic syndrome, obesity, hypertension, and osteoporosis. (ndnr.com)
  • testicles
  • Once the sperm is produced in the testicles, delicate tubes transport them until they mix with semen and are ejaculated out of the penis. (punchng.com)
  • Anabolic steroids taken to stimulate muscle strength and growth can cause the testicles to shrink and sperm production to decrease. (punchng.com)
  • Men who develop orchitis, inflammation of the testicles, are slightly more likely to be rendered infertile. (infertilityhomoeopathy.com)
  • female reproductive tract
  • Capacitation: The process by which sperm are altered ( usually during their passage through the female reproductive tract ) that gives them the capacity to penetrate and fertilize the ovum. (drmalpani.com)
  • pregnancy
  • Genetic and epigenetic alterations of the sperm may, therefore, have important consequences on early pregnancy. (punchng.com)
  • It is now noted worthy to realise that men may have a role to play when their partner has recurrent pregnancy loss. (punchng.com)
  • Genetic
  • In rare cases, infertility in men is caused by a genetic disease such as cystic fibrosis or a chromosomal abnormality . (americanpregnancy.org)
  • Thus, an appropriate male evaluation may allow the couple to better understand the basis of their infertility and to obtain genetic counseling when appropriate. (auanet.org)
  • Although it is possible for men to father children into old age, the genetic quality of sperm, as well as its volume and motility, all typically decrease with age. (wikipedia.org)
  • decrease
  • Withania is able to decrease the number and severity of chronic stress-induced ulcers, reverse chronic stress induced inhibition of male sexual behavior, and chronic stress-induced immuno-suppression. (herbal-viagra-erection.com)
  • absence
  • Epigenetic alterations in the sperm, such as altered chromatin packing, imprinting errors, absence or alteration of the centrosome, telomeric shortening, and absence of sperm RNA, can affect some of the functional characteristics leading to early embryo loss. (punchng.com)
  • production
  • Cadmium, being chemically similar to zinc, may replace zinc in the DNA polymerase, which plays a critical role in sperm production. (wikipedia.org)
  • Problems with any of these systems can affect sperm production. (punchng.com)
  • Even azoospermic patients may have active sperm production or could have sperm production induced with treatment. (auanet.org)
  • In men with a normal level of sperm production (normozoospermia), the percentage of sperm DNA fragmentation is positively correlated with age, and inversely correlated with progressive sperm motility. (wikipedia.org)
  • insufficient
  • An insufficient number of sperm may be related to many of the issues in the point above, as well as physical problems within the scrotum (such as swelling, physical trauma or immunological issues). (sharecare.com)
  • On the other hand, due to large intra -and inter-individual fluctuations of the sperm it is difficult to demonstrate the superiority of a treatment over placebo due to an insufficient number of patients (type 2 error). (gfmer.ch)
  • uterus
  • In a woman's body the tube allows passage of the egg from the ovary to the uterus and helps fertilization is sperm is present. (infertilityhomoeopathy.com)
  • Artificial insemination by husband (A.I.H.) is a technique in which the sperms are directly deposited in the uterus with the help of a tube known as fine catheter. (indiaparenting.com)
  • Once the semen sample is ready woman has to undergo IUI (Intra Uterine Insemination) through which the sperms are put in her uterus. (indiaparenting.com)
  • hormonal
  • Treatment for male infertility should be targeted to the aetiological factors whenever possible, and includes hormonal treatment, hormonal modulators, corticosteroids, antioxidants, and surgery. (acupuncture.org.uk)
  • hormones
  • Male sex hormones. (drmalpani.com)
  • There is suspicion that many toxic substances, including several types of medication and hormones, and also constituents of the diet, influence sperm quality. (wikipedia.org)
