Abstract:
SUMMARYFree-spawned eggs are typically enclosed within accessory structures that are shed early in development. Most research on the role of these structures in fertilization has focused on chemical constituents and their influence on sperm—egg interaction. Here I test an alternative hypothesis that accessory structures play an important physical role in fertilization by increasing the size and buoyancy of the egg, making it a better target for sperm. In the sand dollar Dendraster excentricus, the jelly coat increases egg target size sixfold. At nonsaturating sperm concentrations,fertilization

Abstract:
A thorough understanding of the mechanisms leading to the interaction between the sperm and the ovum in the process of fertilization in birds can facilitate more effective programming and control of the reproduction of these animals in breeding farms. In addition, it may allow the introduction of extracorporeal fertilization techniques, which may be important in the creation of transgenic animals and the reproduction of endangered species. In birds, the process of fertilization is not well known. It is conditioned by a series of interactions between mature reproductive cells. Oocytes are forme

Abstract:
This review compares sperm production in the tammar wallaby and eutherian mammals, particularly the rat. The capacity of sperm to fertilize an ovum when they leave the testis and the changes they undergo in the epididymidis are considered. The structural differentiation and regulation of the extratesticular duct system is assessed and related to the reabsorption and secretion of water, inorganic ions and proteins, and the interaction of sperm and proteins synthesized and secreted by the epididymidis. Adaptations of the cauda epididymidis for storing spermatozoa are also considered. It is sugge

Abstract:
Sandhoff disease is a human lysosomal storage disease. In a knockout mouse model of Sandhoff disease, which lacks the β-subunit of β-hexosaminidase A (Hex A, αβ subunits) and B (Hex B, ββ subunits), the mutant homozygous mice (Hexb–/–) are healthy until 15 weeks of age when they develop neurodegenerative symptoms. This study was designed to analyse the fertility profile of male and female Hexb–/– mice. Mating behaviour of Hexb–/– mice was assessed at different ages. The ovarian function of Hexb–/– females was determined by superovulation studies. The quality of spermatozoa and ova was assessed

Abstract:
The sperm tail has a key role in male fertility, since it is responsible for motility, driving sperm toward and into the ovum. In this study, we characterized a sperm tail protein, testis specific protein 1 (Tpx-1), which is exclusively expressed in sperm and is localized to the acrosome and the outer dense fibres (ODF) of the sperm tail. We carried out yeast two-hybrid screening using an adult testis cDNA library to identify interacting protein partners of Tpx-1. A number of putative Tpx-1 interacting proteins were identified including a novel germ cell-specific protein, gametogenetin (Ggn).

Abstract:
Spermatozoa binding to the zona pellucida is an early, critical event leading to fertilization and early pre-embryo development. Fertilization involves a complex and orderly sequence of events that is completed at syngamy, which is defined as the union of the two sets of haploid chromosomes to form a new diploid fertilized ovum (zygote). In order to be able to fertilize an oocyte, spermatozoa need to undergo a process called ‘capacitation’, which is usually defined as a series of changes that renders the sperm cells capable of undergoing the acrosome reaction.

Abstract:
The complex and coordinated set of events leading to sperm and egg maturation and transport in the female genital tract that culminates in fertilization is one of the most remarkable phenomena in nature. This set of events is followed by the equally important unique processes of implantation, fetal maturation, and parturition. The hormonal changes that regulate these events are dependent on the close interaction of the fetal-placental-maternal unit. Just before ovulation, the egg, which has been arrested in the diplotene stage, completes the first meiotic division and forms the first polar body. The second meiotic division starts at the time of ovulation but ends only after fertilization by a sperm. The process of egg maturation is regulated through a closely interrelated set of hormonal events, most notably involving follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estrogen. At the time of ovulation the fimbria of the oviduct are closely applied to the surface of the ovary. The extruded oocyte and adherent granulosa cells, known as the cumulus oophorus, is collected by the ciliated fimbrial end of the fallopian tube. The transport of the egg into the end of the fallopian tube occurs within minutes and is regulated primarily by ciliary action. The cumulus cells are able to communicate with one another via a network of intercellular bridges through the zona pellucida to the perivitelline space. The cumulus cells have also been reported to play a role in nutrition and maintenance of the ovum. There are three different stages of passage of the ovum through the fallopian tube. The first stage includes the transfer of the ovum from the fimbriated end of the fallopian tube until the egg reaches and is retained at the ampullary-isthmic junction. The ampullary-isthmic junction is a functional block but is not a clearly defined anatomical structure. The ovum remains at this junction for 1–2 days, during which time fertilization occurs.
