Endocrinopatias e infertilidade masculina

Authors: Machado, João Pedro Neiva;

Endocrinopatias e infertilidade masculina

Abstract

Contexto: A infertilidade afecta cerca de 15% de todos os casais em alguma altura da sua vida reprodutiva. O elemento masculino do casal, associado a alterações relativas dos parâmetros seminais, contribui para 50% dos casos de infertilidade. Alguns destes casos devem-se a uma endocrinopatia que pode ser tratável e, eventualmente, reversível. Objectivo: Pretende-se com este trabalho discutir as principais endocrinopatias relacionadas com a infertilidade masculina. Material e métodos: Foi feita uma revisão da literatura publicada na PubMed e Repositório da Universidade do Minho, atribuindo-se particular ênfase aos dados mais recentes sobre as alterações endocrinológicas subjacentes às causas de infertilidade. Resultados: As alterações endócrinas responsáveis por infertilidade masculina podem resultar de alterações no eixo hipotálamo-hipófise-gónadas, de alterações nas próprias gónadas ou de manifestações de alterações sistémicas. As anomalias específicas podem ser congénitas ou adquiridas e podem ser categorizadas segundo o defeito ao nível do eixo hipotálamo-hipófise-gónadas. A terapêutica endócrina dirigida pode ser aplicada a doentes que tem níveis alterados de hormona libertadora de gonadotrofinas, gonadotropinas, androgénios e hormonas associadas como prolactina, hormona do crescimento e hormona estimuladora da tiróide. Estes distúrbios ao nível de outras hormonas como os estrogénios, prolactina, hormonas tiroideias e glucocorticoides, entre outras, são causas endocrinológicas de infertilidade potencialmente passíveis de terapêutica direcionada. Conclusão: As anomalias endócrinas permanecem como uma importante etiologia da infertilidade masculina, estando por vezes associadas a patologia médica significativa que pode requerer tratamento direccionado. A terapêutica hormonal de substituição e o auxílio a técnicas de procriação medicamente assistida podem reverter a infertilidade num grande número de casais com factor masculino presente

Context: Infertility affects about 15% of all couples at any given time of their reproductive life. The male factor of the couple associated with relative abnormalities of the seminal parameters accounts for 50% of the cases. Some of these cases are due to an endocrinopathy that might be treatable and possibly reversible. Objective: The aim of this paper is to discuss the main endocrinopathies involved in male infertility. Material and methods: A review was made from the PubMed database and Repositorium of the University of Minho. It was given particular emphasis on the recent knowledge about endocrine causes of infertility. Results: The endocrine changes responsible for the male infertility can arise from abnormalities in the hypothalamus-pituitary-gonads axis, from abnormalities of the gonads as manifestations of systemic diseases. The specific abnormalities can be inherited or acquired and can be classified according to the defect on the hypothalamus-pituitary-gonads axis. Directed endocrine therapy may be used in patients with altered levels of gonadotropin releasing hormone, gonadotropins, androgens and associated hormones like prolactin, growth hormone and thyroid stimulating hormone. Abnormalities of estrogens, prolactin, thyroid hormones and glucocorticoids are endocrine causes of infertility possibly treatable with specific agents. Conclusions: Endocrinopathies remain as an important etiology and may be associated with significant medical pathology that, in turn, may require directed treatment. Hormonal replacement therapy and assisted reproductive technology might revert infertility in a vast number of couples with the male factor being present.
