Correlation between in vitro fertilization and human sperm density and motility
Correlation fertilization human sperm density motility
2009/2/23
The conventional sperm characteristics of density (millions per milliliter) and motility, scored in a semi-subjective way, were correlated with results of an on-going in vitro fertilization and em...
Correlation between human sperm swelling in hypoosmotic medium（hypoosmotic swelling test）and in vitro fertilization
human sperm hypoosmotic medium（hypoosmotic swelling test） vitro fertilization
2009/2/23
Human ejaculates (n = 83) were analyzed for standard sperm parameters (concentration, motility, and morphology), as well as for the ability of the spermatozoa to react (swell) in a hypoosmotic mediu...
In Vitro Sperm Capacitation and In Vitro Fertilization with Normal Development in the Rabbit
sperm capacitation in vitro fertilization embryo culture embryo transfer spermatozoa oocytes rabbit
2009/2/19
The objective was to obtain in vitro sperm capacitation and fertilization to approximate the normal in vivo processes. Rabbit oocytes from follicles, ovarian surfaces, and oviducts were fertilized...
Characterization of Cholinomimetic Agents that Inhibit In Vitro Fertilization in the Mouse
sperm binding cholinomimetics
2009/2/19
Spermatozoa from the cauda epididymidis of the mouse bind 3-quinuclidinyl benzilate (QNB), a highly specific antagonist of the muscarinic type of acetylcholine receptor; inhibition of in vitro ferti...
Evaluation of the effect of the absence of sperm with rapid and linear progressive motility on subsequent pregnancy rates following intrauterine insemination or in vitro fertilization
Sperm separation motility gradIng linear velocity
2009/2/16
The objective of this study was to investigate the association of rapid and linear progressive motility in seminal and Percoll-separated sperm with the outcome of intrauterine insemination (IUI) and...
Hemizona index（HZI）demonstrates excellent predictability when evaluating sperm fertilizing capacity in in vitro fertilization patients
IVF predictability Hemizona assay IVF
2009/2/12
The objective of this work was to assess the power of the hemizona assay to predict in vitro fertilization (IVF) results using receiving operating characteristics (ROC) analysis. In a tertiary medical...
Atrial natriuretic peptide（ANP）as a stimulus of the human acrosome reaction and a component of ovarian follicular fluid：correlation of follicular ANP content with in vitro fertilization outcome
Noncapacitated spermatozoa capacitation
2009/2/12
Atrial natriuretic peptides (ANPs) from several species induced the human acrosome reaction. The maximal response was highest for human ANP (18.6% above unstimulated or baseline values) and decrea...
Morphology of testicular spermatozoa obtained by testicular sperm extraction in obstructive and nonobstructive azoospermic men and its relation to fertilization success in the in vitro fertilization-intracytoplasmic sperm injection system
Morphology testicular spermatozoa testicular sperm extraction azoospermic men
2008/12/26
The aim of the present study was to evaluate the morphology of testicular spermatozoa by 3 different determinants. Sperm cells were obtained and their morphology was evaluated from 27 testicular spe...

Unruptured ovarian pregnancy following in-vitro fertilization: Missed diagnosis followed by successful laparoscopic management
In-vitro fertilization laparoscopy ovarian pregnancy
2008/11/13
Ovarian pregnancy after in-vitro fertilization is rare and can be easily missed unless there is a high index of suspicion. Here we present such a case which was missed initially but was later successf...
