“…The presence of two peaks of galactose incorporation and the correlation between changes in plasma oestradiol level and galactose incorporation support an association of the hormone level and the synthetic activity of the columnar cells of the human cervix. The rather low correlation might be explained by (1) the rather high error in the value of Ratio I per biopsy (5-72%) which might be related to the great variations in appearance of the epithelial cells (Bradburn & Webb, 1951), (2) the sometimes long intervals between biopsy samples which might obscure peaks and (3) the probable existence of a lag phase between the oestradiol level and galactose incorporation. If such a lag phase does exist, increasing values of the one would be accompanied by already decreasing values of the other.…”

The rate of glycoprotein synthesis by the columnar cells of the human endocervix was measured during one cycle in 12 women by autoradiography. An increase in the rate of synthesis was associated with an increase in the plasma oestradiol concentration. A change in progesterone concentration in the blood did not seem to influence cervical glycoprotein synthesis. The ratio between the different cell types in the epithelium, basal cells, ciliated cells and mucus cells did not show cyclic variation in the cycles studied.

“…26 The existence of morphological changes in the human endocervical mucosa before, during, and after the ovulatory cycle has been controversial probably due to technical difficulties in obtaining satisfactory and representative human material. [28][29][30] The height of endocervical mucous cells, a putative indicator of secretory activity, varies during life in nonhuman primates with estrogen-related peaks at the onset of the new menstrual cycle, at ovulation, and in the midluteal phase. 30 From the data presented in this article, it appears that mucins are present in endocervical mucous cells throughout life.…”

“…There are widespread differences in the reactions of the stromal glands and arteries, but menstruation will occur when the supporting hormonal stimulus is withdrawn, whatever the nature of the preceding structural response. Earlier claims that there are cyclical changes in the histological appearances of the human endocervix have been denied (42).…”

In 1910, the late Dr. F. H. A. Marshall published the first edition of his Physiology of Reproduction. It represented the first attempt to assemble in the English language the knowledge that was available about the subject of reproduction. A second edition appeared in 1922, but unfortunately missed the very rapid expansion of the subject, especially on the endocrinological side, which took place during the 1920's. A third edition of Marshall's classic, of which one volume has now been published under the editorship of Parkes, again brings the subject up to date, and in the same encyclopaedic form first attempted by Marshall himself.The volume that has appeared (Vol. II) corresponds to the second half of the single volumes of the first and second editions (1). Its chapters deal with the history of the fertilized ovum, cleavage and implantation, placentation, foetal and maternal physiology, parturition, lactation and fertility, and show up, very clearly, the areas in which most progress in knowledge has been made in the past 30 years.Since 1922, we have been provided with detailed knowledge about the chemistry and cytological nature of the ova of different species. Develop ments in microscopy and in methods of tissue culture have made possible the direct study of cleavage in many mammalian species. Another achieve ment of the past 30 years is an understanding of the transport of sperm and ova, and of the factors concerned in the spacing of blastocysts, matters which, in the second edition of Marshall's book, could be dealt with in very few words, in spite of the fact that artificial insemination of farm animals was already being practised. On the other hand, the precise roles of blasto cyst and endometrium in the process of implantation are as uncertain to day as they were 30 years ago, even though the actual facts of implantation may be very much better understood, not only in nonprimate mammals but also in monkeys and man. We owe this advance mainly to the fact that it has become possible to obtain for study material that can be timed in rela tion to the ovarian and uterine cycles.The 1910 chapter on "Foetal Nutrition and the Physiology of the Pla centa" was reprinted almost unchanged in 1922, Marshall noting at the time that little new on this subject had appeared in the preceding decade. Infor mation about the macro-and microscopic structure of the placenta is now 1 The survey of the literature pertaining to this review was completed in June, 1952.
