Relationship between sperm parameters and intracytoplasmic sperm injection outcome

Middle East Fertility Society Journal, 2015
Objectives: With the adventure of intracytoplasmic sperm injection (ICSI) technique, great progresses have developed in the treatment of infertility. Concentration on the properties of male’s gamete has been encouraged by the increasing concerns about ...

Recent advances in micromanipulation and transgenesis in domestic mammals [PDF]

, 2011
Background: Intracytoplasmic sperm injection (ICSI) involves mechanical transfer of a single sperm cell into ooplasm. A new application has been recently found for ICSI, the production of transgenic animals. Since the birth of ‘‘Dolly’’, the first adult

Estimating Causal Effects of Third‐Stage Management on Postpartum Haemorrhage in a Midwifery Context: An Evidence Synthesis Approach for Constructing Directed Acyclic Graphs

Paediatric and Perinatal Epidemiology, EarlyView.
ABSTRACT Background Estimating the causal effect of third‐stage management approaches on preventing postpartum haemorrhage (PPH) in the context of physiologic birth using observational data requires conditioning on specific variables, with selection relying on assumptions about their roles in the exposure‐outcome pathway that are rarely made explicit ...

Oocyte activation: The impact of calcium signals on fertilization [PDF]

, 2008
Fertilization is triggered by changes in intracellular calcium concentration. In mammals, these transients in ooplasmic calcium concentration take the form of repetitive spikes, so called calcium oscillations (Ca2+-oscillations).

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

The effect of advanced paternal age on the outcomes of assisted reproductive techniques among patients with azoospermia using cryopreserved testicular spermatozoa

Taiwanese Journal of Obstetrics & Gynecology, 2013
Objective: To determine whether advanced male age influences the outcome of intracytoplasmic sperm injection (ICSI) following the cryopreservation of spermatozoa obtained through testicular sperm extraction (TESE).

Chromosomal disorders and male infertility [PDF]

, 2011
Infertility in humans is surprisingly common occurring in approximately 15% of the population wishing to start a family. Despite this, the molecular and genetic factors underlying the cause of infertility remain largely undiscovered.

A comparative pharmacokinetic evaluation of two aqueous progesterone 25 mg injections in healthy postmenopausal women under fasting conditions: An open‐label, balanced, randomized, two‐treatment, two‐period, two‐sequence, single‐dose, crossover bioequivalence study

Clinical Pharmacology in Drug Development, Volume 15, Issue 2, February 2026.
Abstract The growing demand for assisted reproductive technology (ART) has increased the need for effective luteal phase support. Progesterone, essential for maintaining early pregnancy, is a critical component of ART. This open‐label, balanced, randomized, two‐treatment, crossover, single‐dose study compared the bioequivalence of aqueous progesterone ...
