Ovarian volume, antral follicle count and chronological age are all individually predictive of menopausal status, with similar accuracies.

Ovarian volume differs according to age in premenopausal and postmenopausal women. Menopausal status is more important than age in determining ovarian volume. The data suggest that ovarian volume and age are quite accurate in predicting menopausal status.

An objective and individualized approach of in vitro fertilization techniques tends to decrease costs and improve the experience of infertile couples during treatment. The use of available technologies to diagnose and treat infertility based on scientific evidence seems to be the best practice, which is the guideline that motivates this review on the available techniques for laboratory oocyte insemination. Conventional IVF, the pioneering technique, was initially used in the treatment of tubal obstruction infertility, successfully expanding the treatment of infertile couples presenting with several other factors. However, it was less effective in cases of severe male factor infertility. Intracytoplasmic sperm injection, which was developed in 1992, proved to be the method of choice for treating couples with severe male factor infertility. Since then, it has been increasingly used regardless of the infertility factor. This review discusses the effectiveness of conventional in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) when the male factor is absent in all aspects, as technical and clinical outcomes, associated risks, adjustments for using with other technologies and costs. Finally we discuss the advantages and disadvantages of each one, with all aspects reviewed.

a ciclos menstruais longos e amenorréicos, hirsutismo e ovários policísticos aumentados. A neurotransmissão pode ser também afetada, nos regimes de emagrecimento por restrição calórica, nas situações de exercícios físicos excessivos ou em situações de estresse. Na presença de obesidade, acne, hirsutismo e alteração menstrual, independente da idade ginecológica, a possibilidade de anovulação crônica deve ser investigada de imediato.
