The clinical fertility of 1077 men investigated with sperm analysis including sperm count and semen volume during the years 1950-52 was studied 20 years later using a questionnaire, replied by 785 (72.9%). There was a significant correlation (P less than 0.01) between sperm count and number of living children, but no relation to abortions and pathological pregnancies. Furthermore, sperm count was correlated (P less than 0.01) to time interval from wish of pregnancy to pregnancy obtained. Of 53 men with sperm count less than or equal to 5 mill/ml 22.6% obtained living children compared with 52.2-63.1% living children in 730 men with sperm count greater than 5 mill/ml. Sperm count is concluded to be proper for fertility classification, and sperm count 5 mill/ml is found to be the clinically significant borderline of male infertility. There was no relation between semen volume and pregnancies obtained, however, there was a statistical relation (P less than 0.01) to time interval to pregnancy obtained. Semen volume is concluded not to be suited for fertility classification.
The clinical fertility of 1077 men investigated with semen analysis including detection of morphologically abnormal spermatozoa during the years 1950-52 was studied 20 years later using a questionnaire replied to by 785 (72.9%). There was a significant correlation (P less than 0.01) between increasing number of abnormal spermatozoa and decreasing chance of getting living children, but no relation to abortions and pathological pregnancies. Moreover, there was a significant correlation (P less than 0.01) to time-interval to first pregnancy. Median values for those obtaining living children was 25% abnormal spermatozoa compared with 28% for those not doing so. Up to 60% abnormal spermatozoa, fertility was not reduced, and the borderline between normal and reduced male fertility is therefore defined to be 60% morphologically abnormal spermatozoa.
A young female with local panatrophy of the right-side extremities affecting all mesodermal layers--dermis, subcutaneous tissue, muscles, and bone--is described. The atrophies were strictly linear. Ultrastructurally, collagen fibrils of the reticular dermis from the atrophic area consisted of two types, a large population of fibrils with decreased diameter and round cut-surface, and a small population with increased diameter and a "flower-like" cut-surface. Collagen analysis revealed a reduced hydroxyproline concentration and content per mm2 skin in atrophic area as compared with the perilesional and regional control. Urinary excretion of hydroxyproline was normal. Glycosaminoglycan analysis showed a less reduced content of hexosamine and uronic acid in the atrophic area per mm2 skin, but no differences in the concentrations. Consistently, the gel/fibre ratio (uronic acid/hydroxyproline) was found slightly elevated in atrophic skin. The proportions of the individual glycosaminoglycans heparin, dermatan sulphate, hyaluronic acid and chondroitin sulphates were not affected. It is concluded that reduced collagen and ultrastructural changes of collagen fibrils are significant features in local panatrophy. The significance of local foetal factors affecting the somatic mesoderm is discussed.

The Hammen semen quality classification system is a fertility index with six qualities based on sperm count, assessment of sperm motility, number of immotile spermatozoa, number of abnormal sperm heads, and sperm viability. It was developed by Hammen during the 1940s. In the present study, the fertility of 1077 men classified during the years 1950 to 1952 was assessed after 20 years. There were significant correlations between those obtaining living children (P less than 0.01) and those with good semen quality, and between number of children obtained (P less than 0.001) and good semen quality. Moreover, the time interval between attempts to impregnate and obtainment of pregnancy was correlated (P less than 0.01). It is concluded that the Hammen semen classification system is suitable for assessing male clinical fertility.
It has been suggested that the Okabayashi technique for radical hysterectomy in cervical cancer results in fewer urological complications as compared with the Wertheim-Meigs technique. Of 479 women with cervical cancer operated on consecutively during the period 1963 to 1978 by the Okabayashi operation, 52 (10.8 per cent) had urological complications (17 bladder and ureter injuries, 35 fistulae and strictures). Thirty-five elective urological operations were required (Table IV). Operative mortality related to urological complications was 1/479. Compared with an earlier series of 397 women operated on in our department, mainly by the Wertheim-Meigs operation, the Okabayashi operation did not result in significantly fewer urological complications. However, because of technical advantages and possible better radicality the Okabayashi operation for cervical cancer is still preferred.
With the purpose of investigating effectivity and acceptability of an oral contraceptive containing micronized natural estrogens (estradiol-17 beta 4 mg + estriol 2 mg/norethisterone acetate 3 mg per tablet) versus a contraceptive containing artificial estrogen (ethinyl estradiol 50 micrograms/ norethisterone acetate 3 mg per tablet), a controlled double-blind investigation was performed in 111 young women. The investigation was designed for 12 cycles. The tablets were given consecutively for 3 weeks with 1 week's interruption. In the natural estrogen group 57 women completed 504 cycles, in the artificial estrogen group 54 women completed 510 cycles (Table 1). No pregnancies occurred. There were highly significantly more terminations due to bleeding irregularities (p less than 0.001), and highly significantly more spotting (p less than 0.001), breakthrough (p less than 0.001) and amenorrhea (p less than 0.001) episodes in the natural estrogen group (Tables II and III). Bleeding irregularities on natural estrogens did not subside during the trial (Table IV). There were a few more psychiatric and CNS symptoms on natural estrogen (p less than 0.05), but other side effects did not differ between the two preparations (Table V). Blood pressure and weight did not vary significantly. Despite documented metabolic advantages, the natural estrogen tablet investigated was not found to be clinically acceptable for general usage because of the high incidence of bleeding irregularities. It is conceivable that a change of the estrogen/gestagen ratio, using a variable 3-week schedule, would reduce the number of bleeding irregularities.
