The distinction between worker and reproductive castes of social insects is receiving increased attention from a developmental rather than adaptive perspective. In the wasp genus Polistes, colonies are founded by one or more females, and the female offspring that emerge in that colony are either non-reproducing workers or future reproductives of the following generation (gynes). A growing numbe...
Based on observational studies comparing social organization and reproductive behavior of equids breeding under feral, semi-feral, and domestic conditions, a series of comparisons and findings on reproductive physiology and behavior are presented. Simple changes in management and handling of mares and stallions that can improve reproductive efficiency and fertility or that can overcome specific...
The role of prostaglandin in reproductive physiology is reviewed with particular emphasis on their possible importance in ovulation in humans. A possible interaction between gonadal steroids, biogenic amines and prostaglandin at hypothalamic-pituitary level, in relation to the release of luteinizing hormone releasing factor, and LH release are noted, and it is suggested that high oestrogen leve...
IN this paper, I shall not attempt to list chronologically the advances which have been made in reproductive physiology but will merely discuss a few which happen to be of greater interest to me. Regrettably, modern biological textbooks provide little information on the historical background to the advances which have been made in various phases of biology. Obviously, teachers have had to choos...
RPCI-42 Bovine Bacterial Artificial Chromosome (BAC) library was screened with oligonucleotide sequences corresponding to specific elements of the 5 UTR sequence of bovine PC and to a region of the coding sequence. Two BACs that hybridized to all probes were selected for further analysis. A partial restriction map of the BACs was made with oligonucleotides corresponding to the coding region and...

Basic understanding of the male reproductive system is fundamental in effective evaluation and treatment of male infertility. This chapter is a concise introduction to the male reproductive anatomy and the intricately designed process of spermatogenesis along with its hormonal control.
THE title of this monograph is too broad for its limited though valuable approach. The approach is that of morbid anatomy and clinical observation and the term "physiology" is justified only since it is an attempt to define the normal changes of the post-partum period. Essentially these studies are limited to a histological study of the endometrium from soon after delivery till nine months ther...
Assisted reproductive technologies (ART) have been used successfully in humans, domestic and laboratory species for many years. In contrast, our limited knowledge of basic reproductive physiology has restricted the application of ART in companion animal, non-domestic and endangered species (CANDES). Although there are numerous benefits, and in some cases a necessity, for applying ART for the re...
