Introduction: Klinefelter syndrome (KS) is the most common sex chromosomal anomaly with hypogonadism being a common feature in this syndrome. The ejaculate volume is about normal to low in men with this syndrome. In the present report, we describe the successful treatment of a lifelong anejaculation in a man with KS. This represents the first report of successful treatment of anejaculation in KS. Case presentation: A 24-year-old Caucasian man presented with a lifelong history of failure of ejaculation. A diagnostic work-up revealed the existence of KS and administration of human chorionic gonadotrophin restored the ejaculation. Conclusion: This case report confirms further the increased prevalence of ejaculatory disorders among men with KS in whom associated hypogonadism should be considered a cause of anejaculation. Diagnosis of KS is often delayed. Early diagnosis of the syndrome before puberty is highly recommended and desirable to maintain quality of life.

Floral and Leaf Anatomy of Hibiscus Species

by U. A. Essiett and E. S. Iwok

Original Research

Comparative anatomical studies of the leaves and flowers of H. arnottianus, H. surattensis, H. acetosella and H. rosa-sinensis are described. The anisocytic stomata was the commonest followed by brachyparacytic, anomocytic, staurocytic stomata and laterocytic stomatas respectively. H. acetosella are distinguished on other species by having laterocytic stomata on both surfaces of leaves and parallel contiguous stomata are found on abaxial surface while in H. rosa-sinensis laterocytic is found only on adaxial surface. There are five different types of abnormal stomata, unopened stomatal pore, two stomata sharing one subsidiary cell, parallel contiguous stomata and aborted guard cell found in all the surfaces of the leaves and flowers. In addition parallel contiguous stomata are found on adaxial surface of H. rosa-sinensis and abaxial surface of H. arnottianus flower. H. rosa-sinensis had five-armed trichome on the abaxial surface that helps in distinguishing it from other species studied. Crystal druses are only present on both adaxial surface of H. arnottianus and H. rosa-sinensis leaf and on the abaxial surface of H. acetosella flower. The shape of epidermal cells, anticlinal cell walls, guard cell areas, stomatal index and trichomes varied. The results obtained could be used as diagnostic tool for plant identification and preparation of monograph on the species.
