Morphology of spermatozoa in infertile men with and without varicocele.

Abstract: This study was carried out to evaluate the morphology of spermatozoa in infertile men with and without varicocele. A series of 285 ejaculates were fully evaluated for seminal volume, sperm count, motility, and morphology, and classified into fertile (165 subjects), infertile without varicocele (93 subjects) and infertile with varicocele (27 subjects). Sperm morphology was classified by multiple entry criteria and recorded as normal, abnormal with head, midpiece, or tail single anomaly or abnormal with simultaneous multiple abnormalities. Semen volume was almost identical in the three groups. Among the infertile men, sperm count was lower in those having a varicocele, but conversely those with varicocele had a higher percentage of motile spermatozoa, higher percentage of spermatozoa with forward movement and higher sperm velocity. There were higher proportions of spermatozoa with abnormal morphology, total number of anomalies, and multiple anomalies in infertile men, both with and without varicocele, than in fertile men. The percentage of abnormal spermatozoa was higher in infertile men with varicocele than in those without varicocele. The pattern of sperm morphology differed between the infertile and the fertile group, and with the presence or absence of varicocele. In the presence of varicocele, only the incidence of elongated (tapered) forms was significantly increased.

The Corpus Luteum in Infertile Patients Found during Laparoscopy

Abstract: A series of 407 infertile patients underwent luteal phase laparoscopy and endometrial biopsy as a part of their infertility workup. In 91% of the patients, a good correlation between the results of endometrial biopsy and those of laparoscopy was found. In 8% of the patients a secretory endometrium was found, but the laparoscopy did not show any luteal structures on the ovaries. Seventy-one percent of the patients had corpora lutea, but the stigma was only present in 17.5% of the series with secretory endometrium. Because of the stigma findings, only 325 patients with secretory endometrium were evaluated. The stigma was more frequently seen when laparoscopy was performed between day 17 and day 19 of the cycle. On the other hand, the stigma was also more frequently seen when laparoscopy was performed between 10 and 12 days before the actual onset of the next period. We conclude that the frequency of stigmata at the corpus luteum is a matter of the time in the cycle when laparoscopy is performed, and the particular cycle length of the patient should be considered.
