A new technique based on the motile sperm organelle morphology examination (MSOME) at a magnification of at least ×6000 has been developed. The MSOME assesses the nucleus, for both shape and chromatin content, which is the most important sperm organelle in influencing intracytoplasmic sperm injection (ICSI) outcomes.

Sperm morphology has been described as one of the major determinants of male in vitro fertility. However, the standard morphology evaluation on random stained cells from the ejaculate is of limited value during ICSI. Current research is directed towards the dysmorphisms of the sperm head.A new technique based on the motile sperm organelle morphology examination (MSOME) at a magnification of at least ×6000 has been developed. The MSOME assesses the nucleus, for both shape and chromatin content, which is the most important sperm organelle in influencing ICSI outcomes. The goals for this study are to identify whether there is a connection between morphologic sperm normalcy under high magnification and (i) semen analysis according to the new World Health Organization (WHO) reference values and (ii) ICSI outcomes.

Inclusion Criteria:

• Women with body mass index (BMI) less than 30 kg/m2
• Women with both ovaries and intact uterus

Exclusion Criteria:

• Women with polycystic ovaries syndrome
• Women with endometriosis
• Women with gynaecological/medical disorders
• Couples with any sexually transmitted disease
• Women who had received any hormone therapy for less than 60 days preceding the study
