Abstract

The sperm’s tale

Highlights

This flatness perhaps goes some way to explain the enormous number of Copenhagen’s pedal-driven vehicles, which present a serious hazard to the unwary pedestrian
In a newspaper article [1] entitled ‘The Father’s a Viking’, a mother-to-be describes her experience of travelling to Copenhagen, and parting with £460; she says she will call the resulting daughter Freya, and comments that her own family are from the north and west of the British Isles, and have Scandinavian blood already
Births of children with short-limbed dwarfism were shown by Lionel Penrose in the 1950s [3] to become more likely as paternal age increased, and the same was later shown to be true of a suite of other dominantly-inherited genetic diseases

Summary

Introduction

This flatness perhaps goes some way to explain the enormous number of Copenhagen’s pedal-driven vehicles (mostly of the two-wheeled variety), which present a serious hazard to the unwary pedestrian. This Sperm Bike criss-crosses Copenhagen carrying samples from donors to recipients, and is symptomatic of Denmark’s relaxed attitude to assisted reproductive therapy (ART). As a man gets older, his semen volume and sperm count decline [2], though elderly men still father healthy children, as the lively 96-year-old Ramjit Raghav demonstrated in 2012.
