The development of assisted reproductive technology has made it possible for infertile couples, especially infertile men, to conceive through Intracytoplasmic Sperm Injection (ICSI). However, the success of In Vitro Fertilisation (IVF) and ICSI can be influenced by various factors. This review analyzed the impact of female age, ovarian reserve, male age, and male factor on the outcomes of IVF/ICSI, aiming to determine their practical applicability. The findings suggest that higher female age and alterations in ovarian markers are associated with poorer outcomes, while the predictive value of male age and male factor remains inconclusive and requires further investigation.
The development of assisted reproductive technology has allowed offspring in infertile couples, and specifically, allowed infertile men to conceive through Intracytoplasmic Sperm Injection (ICSI). Despite the proven efficacy of In Vitro Fertilisation (IVF) and ICSI, many factors can influence its success. In this review we present an analysis on the effect of Female age, Ovarian Reserve, Male age and Male factor on the outcomes of IVF/ICSI, to determine if and which can be applied to the practical context. A literature search on PubMed, EMBASE and MEDLINE for relevant articles was elaborated until July 2021, leading to the selection of 234 articles based on their titles. After reading through the abstracts, those that evaluated IVF/ ICSI predicting factors were selected. Finally, only those approaching female age, ovarian reserve, male age and male factor were considered in this review. Higher female age and baseline ovarian markers alterations such as lower anti-Mullerian hormone and antral follicular count, and higher basal follicle-stimulating hormone, were associated with poorer outcomes. The predictive value of Male age and Male factor presented varied results across literature. The multifactorial nature of male fertility makes evaluation difficult. Although the first assessment of male infertility is based on sperm concentration, motility and morphology, semen parameters have shown low prognostic value, whilst sperm DNA alterations gain importance. Nevertheless, results remain controversial. While some factors have proven to predict IVF/ICSI success, other need to be further studied to be applied to practical context to allow the best prognosis possible.
