To be or not to be [fertile], that is the question.

Background: According to our literature analysis, there are no data focused on spermatozoa emotional representations in childless men and data on the emotional repercussions of a diagnosis of infertility on men are still scarce. Thus, in this work, we investigated what the presence or absence of spermatozoa in the semen symbolize for men.

Material And Methods: To answer this question, 441 childless heterosexual men participated in an anonymous, prospective, Internet-based survey.

A human morphologically normal spermatozoon may have noncondensed chromatin.

According to numerous assisted reproductive medicine practitioners, semen with normal characteristics might not require further investigation. However, on the scale of the individual spermatozoon, it is well known that normal morphology does not guarantee optimal nuclear quality. Here, for 20 patients with normal sperm characteristics and a high proportion of spermatozoa with noncondensed chromatin, we subsequently assessed chromatin condensation status (aniline blue staining) and morphology (Papanicolaou staining) of the same 3749 spermatozoa.

[Varicocele and infertility: where do we stand in 2013?].

While the incidence of clinical varicocele is common in infertile men (about 40%), the reasons why varicocele may affect sperm parameters is still unclear. In addition, the improvement of fertility after treatment of varicocele is also a subject of debate. The purpose of this review is to get new insight into the physiopathology of varicocele, its impact on sperm parameters and the effectiveness of varicocele treatment on fertility.

[Ovarian stimulation monitoring: past, present and perspectives].

Since the inception of Assisted Reproductive Technology (ART), knowing the moment of ovulation has always been a priority. Initially, the monitoring was accomplished by observing the luteinizing hormone (LH) surge just before ovulation. Currently, in all ART facilities, the monitoring of all stimulated ovulatory cycles is done by using the conventional two-dimensional (2D) ultrasound to measure follicle diameter and by drawing blood tests that measure estradiol, progesterone, and luteinizing hormone levels.
