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. Sperm were inserted into the oocyte (bar = 100 µm). (B) Marmoset blastocysts produced by ICSI. (bar = 100 µm). Uterine synechiae development is a potential complication after the surgery; therefore, a postoperative HSG should be part of follow-up care. The use of CC is contraindicated in cases of ovarian cyst, pregnancy, and liver disease.

The new generations of available gonadotropins are produced by genetically engineered mammalian cells (ie, Chinese hamster ovary cells), in which the gene coding for the alpha and beta FSH subunits has been inserted (follitropin alfa [eg, Gonal F] and follitropin beta [eg, Follistim AQ]).

Society and culture[edit] Perhaps except for infertility in science fiction, films and other fiction depicting emotional struggles of assisted reproductive technology have had an upswing first in the latter part of the 2000s decade, although the techniques have been available for decades.[76] Yet, the number of people that can relate to it by personal experience in one way or another is ever growing, and the variety of trials and struggles is huge.[76] Pixar's Up contains a depiction of infertility in an extended life montage that lasts the first few minutes of the film.[77] Other individual examples are referred to individual subarticles of assisted reproductive technology Ethics[edit] There are several ethical issues associated with infertility and its treatment.

Passive smoking has also been linked to lower fertility. If the woman is aged over 35 years, the couple may wish to see a doctor earlier, because fertility testing can take time, and female fertility starts to drop when a woman is in her 30s. Combined infertility[edit] In some cases, both the man and woman may be infertile or sub-fertile, and the couple's infertility arises from the combination of these conditions. For a woman to conceive, certain things have to happen: vaginal intercourse must take place around the time when an egg is released from her ovary; the system that produces eggs has to be working at optimum levels; and her hormones must be balanced.[54] For women, problems with fertilisation arise mainly from either structural problems in the Fallopian tube or uterus or problems releasing eggs. Most couples (about 84%) who have regular sexual intercourse (that is, every two to three days) and who do not use contraception get pregnant within a year. Often, but not always, submucosal fibroids can cause heavy periods, or bleeding between periods. 37 Clomiphene has also proven effective for ovulation induction in women with polycystic ovary syndrome.
