Systematic review of hormone replacement therapy in the infertile man

Conclusions Exogenous testosterone inhibits spermatogenesis. Hypogonadal men wanting to preserve their fertility and at the same time benefiting from TRT effects can be prescribed selective oestrogen receptor modulators or testosterone plus low-dose human chorionic gonadotrophin (hCG). Patients treated for infertility with hypogonadotrophic hypogonadism can be prescribed hCG alone at first followed by or in combination from the start with follicle-stimulating hormone preparations.

Abstract Failure of pubertal growth, delay or absence of sexual development, infertility and sexual dysfunction due to hypogonadism and defective spermatogenesis are frequent and well recognized disturbances among male patients with transfusion dependent (TD) thalassaemia major (β-thal). These problems are attributed mainly to the damage caused by chronic anaemia and the deposition of excess iron in the pituitary gland and testicles. This is a short review of male pubertal disorders in patients with β-thal written by pediatric endocrinologists and haematologists with an interest and active involvement, i...

This study provides three interesting insights: i) the probability to retrieve sperm is not related to testicular volume; ii) TRT does not affect sperm retrieval rate (SRR); iii) reduced levels of LH and FSH represent a negative predictor of sperm retrieval in patients with TRT. What Is Known AlreadyClassical KS shows a karyotype with one extra X chromosome in all of somatic cells and clinical manifestations characterized by hypergonadotropic hypogonadism and infertility. Study Design, Size, DurationWe performed a retrospective cohort study. Data from 111 consecutive KS azoospermic patients undergoing testicular ...

Authors: Gravholt CH, Chang S, Wallentin M, Fedder J, Moore P, Skakkebæk A Abstract Although first identified over 70 years ago, Klinefelter syndrome (KS) continue to pose significant diagnostic challenges, as many patients are still misdiagnosed, or remain undiagnosed. In fact, as few as 25% of KS patients are accurately diagnosed, and most of these diagnoses are not made until adulthood. Classic characteristics of KS include small testes, infertility, hypergonadothropic hypogonadism, and cognitive impairment. However, the pathophysiology behind KS is not well understood, although genetic effects are also th...

Abstract AimHypogonadotropic hypogonadism (HH) is a condition caused by the deficient secretion of pituitary gonadotropins, leading to diminished ovarian function. Several studies of in vitro fertilization (IVF) in women with HH revealed acceptable clinical pregnancy outcomes but high multiple pregnancy rates after multiple fresh embryo transfer (ET). The purpose of this study was to analyze the outcomes of combined freeze‐all embryos and single vitrified‐warmed ET in women with HH. MethodsOf 91 infertile women with HH (basal luteinizing hormone and follicle‐stimulating hormone levels

Klinefelter syndrome (KS) is the most frequent chromosome disorder in males (1:650 newborn males), defined by 47,XXY karyotype. The classical phenotype is that of a tall male with relatively long legs, small, firm testes and gynecomastia. Azoospermia and infertility are almost inevitably present, but may be overcome by TESE and ICSI. Nevertheless, a broad spectrum of phenotypes has been described and>70% of the actually existing KS men may remain undiagnosed throughout their lifespan. Accordingly, hypogonadism is usually not evident until early adulthood and progresses with ageing.

Summary In a case‐controlled study, we assessed the expressed seminal NAD‐dependent protein deacetylase (SIRT1) expression in infertile oligoasthenoteratozoospermic (OAT) men associated with varicocoele. Our study involved 81 men, recruited from the University hospitals, after ethical approval and informed consent. They were allocated into fertile normozoospermic men (n = 23), infertile OAT men without varicocoele (n = 23) and infertile OAT men with varicocoele (n = 35). Inclusion criteria consisted of confirmation of abnormal semen parameters and normal female partners whereas exclusion c...

Abstract Congenital hypogonadotropic hypogonadism (CHH) and Kallmann syndrome (KS) are rare, related diseases that prevent normal pubertal development and cause infertility in affected men and women. However, the infertility carries a good prognosis as increasing numbers of patients with CHH/KS are now able to have children through medically assisted procreation. These are genetic diseases that can be transmitted to patients' offspring. Importantly patients and their families should be informed of this risk and given genetic counseling. CHH and KS are phenotypically and genetically heterogeneous diseases in which ...

Authors: Glezer A, Bronstein MD Abstract Prolactinomas are the most common cause of pathological hyperprolactinemia, leading to central hypogonadism and, therefore, a frequent etiology of infertility. Treatment, usually with dopamine agonist (DA), can reverse hyperprolactinemia and hypogonadism, allowing pregnancy in the majority of cases. Bromocriptine is still the DA of choice for such purpose. Important issues in DA-induced pregnancies include fetal exposition, both malformations and neuropsychological development and tumor size increase. Regarding microprolactinomas and intrasellar macroprolactinomas, DA should...

Authors: Drobnis EZ, Nangia AK Abstract Prolonged use of immunosuppressant medications is occasionally seen in infertile men with chronic inflammatory conditions; autoimmune disorders; or an organ or hematopoietic stem cell transplant. Chronic inflammation impacts negatively on male reproductive endpoints, so immunosuppressant therapy can produce improvements. Corticosteroids have been used to treat antisperm antibodies and even as an empirical treatment for male infertility in general. Trials of these methods have provided mixed results on semen quality and fertility, with improvement, no change and negative effec...
