As the indication of assisted reproduction shifted from mere gynaecological indications to andrological indications during the years, this urged andrological research to understand the physiology of male germ cell better and develop more sophisticated techniques to Cited by: IVF involves the mixing of egg and sperm in the laboratory to generate embryos suitable for transfer to a uterus 2 or 3 days later. An IVF cycle in humans usually involves the transfer of at least two embryos at a time. In the United States in , 20% of human IVF transfers involved one or two embryos, 33% involved three embryos, 28% involved.

spermatozoa: [ sper″mah-to-zo´on ] (pl. spermatozo´a) (Gr.) a mature male germ cell, the specific output of the testes, which fertilizes the mature ovum (secondary oocyte) in sexual reproduction. It is microscopic in size, looks like a translucent tadpole, and has a flat elliptical head containing a spherical center section, and a long. malities in spermatozoa can be generated in any phase of the sperm production and life and may be due to endogenous and exogenous conditions, the latter including in vitro manipulation for assisted reproduction and gonadotoxic therapies. In addition, emerging studies point out . Assisted Reproductive Technology (ART) generally is divided into three fields (gametes [spermatozoa and oocytes], embryos, and third party reproduction). These topics can be subdivided into such techniques as husband insemination, in vitro fertilization and embryo transfer, gamete intrafallopian transfer, and zygoteFile Size: KB.

Human reproduction is any form of sexual reproduction resulting in human typically involves sexual intercourse between a man and a woman. During sexual intercourse, the interaction between the male and female reproductive systems results in fertilization of the woman's ovum by the man's are specialized reproductive cells called gametes, created in a process called.

This volume, and its companion volume on the oocyte, provide a wide-ranging analysis of the gametes and their reproductive role in humans. The authors give a detailed account of the spermatozoon that includes particularly helpful information on male infertility and its treatment.

The book starts with an evolutionary perspective before focusing on the molecular and cellular biology of the sperm. Human Reproductive and Prenatal Genetics presents the latest material from a detailed molecular, cellular and translational perspective. Considering its timeliness and potential international impact, this all-inclusive and authoritative work is ideal for researchers, students, and clinicians worldwide.

The fertilization of human oocytes outside of the body, the culturing of the embryo(s) in the laboratory, and the subsequent transfer of embryo(s) to the uterus has resulted in the birth of tens of thousands of children worldwide.

This book covers the genetic damage in spermatozoa that can originate during spermatogenesis, or during transit in both male and female genital tracts. Damage can also be due to ageing, environmental or iatrogenic conditions, as well as to the protocols to cryopreserve and to select spermatozoa in assisted reproduction techniques.

Acosta [et al.] ; editorial advisor, Charlotte Schrader Williams & Wilkins Baltimore This major book - known as 'The Bourn Hall Textbook' - evolved from teaching courses held at this prestigious Clinic - one of the birthplaces of IVF and clinical reproductive medicine.

The content is comprehensive: covering assessment of the infertile couple and both laboratory and clinical aspects of assisted reproductive technologies. The emphasis throughout is on the practical management of. This page introduces spermatogenesis the development of spermatozoa, the male haploid gamete cell.

In humans at puberty, spermatozoa are produced by spermatogonia meiosis in the seminiferous tubules of the testis (male gonad). A second process of spermiogenesis leads to change in cellular organisation and shape before release into the central lumen of the seminiferous tubule.

Cytoplasmic immaturity of the male germ cells used for assisted reproduction can result in fertilization failure, but it can also cause developmental abnormalities in embryos after apparently normal fertilization (Tesarik et al., a). Hence, the relatively low implantation rates in our group of patients with non-obstructive azoospermia may Cited by:   Indeed, successful assisted reproduction is mainly dependent on the quality of the sperm plasma membrane, requiring normal integrity and function to provide motility, acrosome reaction, and fertilization.

Spermatozoa with impaired membrane integrity occur more frequently in infertile men, partly explaining suboptimal results in by:   Human Reproduction, Vol Issue 1, Januaryof a couple in whom the male partner had Kartagener's syndrome.

Cryopreservation of human spermatozoa—introduced in the 's—has been recognized as an efficient procedure for management of male fertility before therapy for malignant diseases, vasectomy or surgical infertility treatments, to store donor and partner spermatozoa before assisted reproduction treatments and to ensure the recovery of a small number of spermatozoa in severe male Cited by: DNA fragmentation of spermatozoa and assisted reproduction technology Ralf Henkel joined the Department of Dermatology and Andrology at the Giessen University as Reproductive Biologist, after obtaining his PhD.

Inhe spent one year as post-doctoral fellow at Tygerberg Hospital (South Africa). He is currently at Giessen University. Cryopreservation of human gametes and embryos is an important and widely used method in most embryology laboratories.

During last years, the practice of single embryo transfer was a greater demand for reliable cryostorage of surplus embryos. Currently, there are two basic principally different methods usable for cryopreservation: slow freezing and by: 1.
