OBJECTIVE:

To review the most recent bibliography to assess and synthesize the most important aspects in relation to the repercussions of hypothyroidism and its association with infertility in women of reproductive age.

METHODOLOGY:

Documentary research study carried out based on the search in PubMed and Google Scholar; from the years 1993 to 2018 with the keywords: subclinical hypothyroidism, hypothyroidism, thyroid dysfunction, thyroid hypofunction, subclinical thyroid disease, pregnancy loss, abortion and pregnancy in Spanish and English and retrospective study in textbooks.

RESULTS:

39 documents were included, selecting the ones with the highest scientific and epidemiological relevance. Hypothyroidism affects women of reproductive age with a prevalence of 0.4-0.5% for the obvious and 2-8% for the subclinical, the latter can result in female infertility and poor reproductive results.

CONCLUSION:

Hypothyroidism is a pathology that affects women, with a higher incidence in the fertile stage. A timely diagnosis and treatment improve the prognosis of fertility, pregnancy and life of the newborn.
