Much has been written of the early history of comparative embryology and its influence on the emergence of an evolutionary developmental perspective. However, this literature, which dates back nearly a century, has been focused on metazoans, without acknowledgment of the contributions of comparative plant morphologists to the creation of a developmental view of biodiversity. We trace the origin...

In these last twenty years, intracytoplasmic sperm injection (ICSI) has efficiently permitted the treatment of male factor infertility (Van Steirteghem et al., 1993); the direct injection of spermatozoa into ooplasm has allowed the embryologist to overcome low sperm motility, poor sperm-Zona Pellucida (ZP) binding, and defective acrosome reaction. Although ICSI has been successfully applied wor...

Jane Maienschein is the daughter of Joyce Kylander [5] and Fred Maienschein [6], and was born in Oak Ridge, Tennessee, on 23 September 1950. She attended MIT as a freshman and then transferred to Yale University [7] in 1969 when Yale decided to admit women undergraduates. In 1972 she graduated with an honors degree in History, the Arts, and Letters having written a thesis on the history of scie...

Anatomical models have always been a mainstay of descriptive embryology [5]. As the training of embryologists grew in the late 1800s, so too did the need for large-scale teaching models. Embryo wax models, such as those made by Adolf Ziegler [6] and Gustav Born [7], were popular in the latter part of the nineteenth century and the early twentieth century as a way to visualize, in three dimensio...

This atlas presents cross-sectional anatomy of human embryos from the first to eighth weeks of life, the time period when most structural relationships are made and most major teratologic changes will have occurred. It is an area of embryology that is not readily accessible from an illustrative standpoint. This volume is an excellent attempt to correct this deficiency. The method of presentatio...

In the late 1950s, Patrick C. Steptoe, a British gynecologist, established contact with Palmer of Paris and Frangenheim of Wuppertal, Germany, and studied laparoscopic technique under the tutelage of these pioneers. Despite the negative attitude among his colleagues, Steptoe soon became one of the most innovative researchers in the field of abdominal endoscopy, particularly laparoscopic sterili...

Embryo warming is an essential practice in IVF. During warming, a blastocyst moved through series of solutions to remove the cryopreservation agent. This technique has demonstrated high survival and implantation rates, but also requires approximately 10-15 minutes bench time for embryologist. study introduces new approach embryo deemed ultra-fast which only involves blastocysts thawing solution...

Sperm morphological analysis (SMA) is an essential step in diagnosing male infertility. Using images of human sperm cells, this research proposes a unique sequential deep-learning method to detect abnormalities semen samples. The proposed technique identifies and examines several components sperm. In order conduct study, we used the online Modified Human Morphology Analysis (MHSMA) dataset cont...

Embryo transfer (ET) is the final and most crucial step of the IVF procedure, characterized by a close collaboration between the clinician and the embryologist. Several studies have shown improvement in clinical pregnancy rates resulting from a focus on different aspects of the gentle embryo transfer technique. Issues such as impact of physician’s experience, trial transfer, catheter type, embr...

The familiar Western taxonomy of the five senses, in which vision is accorded pride of place as "the noblest of the senses," has a venerable history going back to Plato and Aristotle. As several scholars have noted (e.g. Classen 1993, 1997, Herzfeld 2001, Howes 1991, Ingold 2000, Seremetakis 1994, Stoller 1989) vision is closely followed by hearing, both of which are deemed superior to the lowe...
