Treatment of tubal obstruction generally requires referral for subspecialty care. 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.

Infertility in men Semen and sperm The most common cause of infertility in men is poor-quality semen, the fluid containing sperm that's ejaculated during sex. Undescended testicle may be isolated or may be observed as part of a syndrome such as prune belly syndrome.

The sperm must provide the zygote with DNA, centrioles, and activation factor for the embryo to develop. Through this technique, your physician can diagnose abnormalities such as fibroids or polyps within the uterine cavity, and via narrow instruments that run through the hysterosope, can remove or correct the great majority of these abnormalities. Helping our patients develop a deep understanding of their fertility options will make the process smoother.

[126, 127] Tubal reconstruction was the only hope for those patients before assisted reproductive therapy became available.

Thankfully, even when the cause of infertility is not known, various fertility treatments can eventually lead to delivery of a healthy baby.
