Density differences in the spermatozoa of normozoospermic, asthenozoospermic and oligo-asthenozoospermic males.

The spermatozoa densities of the ejaculates obtained daily for five days from infertile males were compared to the spermatozoa densities of the ejaculates obtained from normozoospermic donors. The density distribution of the spermatozoa was established on Percoll columns of discontinuous densities. The density dispersion patterns of five consecutive days from each donor within a donor group were used to establish the main, daily density dispersion patterns. The five, daily, mean dispersion patterns were used to create 3-dimensional graphs of density dispersion variations. The 3-dimensional graphs from the infertile male groups show negligible daily variations as compared to that of the healthy males. The absence of wide daily variations is suggested to be considered as a sign of faulty epididymal functioning.

A single continuous suture as a possible alternative to the interrupted suture for tubal anastomosis.

A simple alternative for microsurgical anastomosis of the fallopian tube is presented. The anastomosis is composed of a single continuous suture (8-0 nylon) extending through the serosa and muscularis, avoiding the mucosa. Experimentally this technique was performed on the uterine horns of 30 female rats and compared with the conventional interrupted suture technique on 30 additional female rats. Patency was established histologically in 100% of operated horns in both groups, with an average nidation index of 0.7 in the study group as compared with 0.6 in the conventional technique group. The results indicate that this simple method of anastomosis, which reduces operative time significantly, does not affect patency or nidation index in this model as compared with the conventional interrupted suture technique. It may, therefore, be a suitable procedure for anastomosis of equal-sized segments of the fallopian tubes, especially in cases of reversal of sterilization.

Declining beta-HCG levels: an indicator for expectant approach in ectopic pregnancy.

Early surgical intervention in ectopic pregnancy is desirable. However, occasionally some patients do not benefit from this approach, as the natural history of ectopic pregnancy is not always tubal rupture or any other catastrophic event. A retrospective as well as a prospective analysis of 144 cases of suspected ectopic pregnancies was performed. The results of this study support expectant management in cases where serum beta-HCG levels are declining, provided the patient is stable and has no acute abdominal symptoms.

The role of ultrasound in ovulation induction by gonadotropins.

Fifty anovulatory women were selected for treatment with gonadotropins. Sixty-five were monitored by serum 17-beta estradiol (E2) levels and human chorionic gonadotropin was administered accordingly. Retrospective evaluation of cycles indicates that the overstimulation syndrome and the number of undesired multiple pregnancies can be reduced after both ovaries have been visualized by ultrasound if, regardless of E2 serum levels, human chorionic gonadotropin is administered when one or two mature follicles are seen and withheld when three or more mature follicles are seen.
