Association between fertilin beta, protamines 1 and 2 and spermatid-specific linker histone H1-like protein mRNA levels, fertilization ability of human spermatozoa, and quality of preimplantation embryos.

open access: yesFolia Histochemica et Cytobiologica, 2008
Fertilization involves a series of cellular interactions culminating in the fusion of gamete membranes, creating a zygote and then an embryo. During the process of human fertilization in vivo or in conventional in vitro fertilization (IVF), sperm must be

Optimized heterologous in vitro fertilization with Iberian ibex sperm and domestic goat oocytes

open access: yesTheriogenology Wild
Assisted reproductive technologies are key to maintain genetic stocks of endangered wild species, such as the Iberian ibex (Capra pyrenaica). Due to the low availability of ibex ovaries, heterologous in vitro fertilization (IVF) with domestic goat (Capra

Intracytoplasmic Sperm Injection Fertilization Rate Does Not Depend on the Proportion of Round-headed Sperm, Small-acrosomal Sperm, or Morphologically Normal Sperm in Patients with Partial Globozoospermia

open access: yesChinese Medical Journal, 2015
Background:. Generally, intracytoplasmic sperm injection (ICSI) may be the preferable method to treat partial globozoospermia, but whether there exist some correlations between ICSI fertilization rate and the proportion of round-headed sperm or ...

Bazi Bushen Capsule restores fertility by targeting mitochondrial health in aging endometrium

open access: yesiMeta, EarlyView.
Bazi Bushen Capsule (BZBS) mitigates age‐related endometrial dysfunction by activating AMPK − SIRT3 signaling. Luteolin, a key bioactive component, restores mitochondrial homeostasis via PINK1/Parkin−mediated mitophagy and Drp1 inhibition, improving endometrial function and fertility potential.

Impact of Methylparaben on Cumulus Cell DNA Integrity and Porcine Oocyte Developmental Competence In Vitro

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Parabens (PBs) are compounds widely used as preservatives in personal care products, food, and pharmaceuticals. Methylparaben (MePB) is the most used by different industries due to its chemical properties and low cost. The high daily human exposure to these compounds has raised concerns about their potential effects on health, particularly on ...

Effect of Propylparaben on In Vitro Maturation of Porcine Oocytes and Embryo Development

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Parabens are synthetic chemicals that, due to their antibacterial and fungicidal effects, are widely used as preservatives in food, cosmetics, and personal care products, such as shampoos, hair conditioners, body creams, soaps, deodorants, makeup, wet wipes, lotions, female hygiene products, and vaginal lubricants. Several years ago, they were

Ophthalmic artery Doppler as potential surrogate marker of angiogenic imbalance in near‐term pregnancy

open access: yesUltrasound in Obstetrics &Gynecology, EarlyView.
ABSTRACT Objectives First, to evaluate whether the ratio of soluble fms‐like tyrosine kinase‐1 to placental growth factor (sFlt‐1/PlGF) is associated with hemodynamic changes in ophthalmic artery (OA) Doppler in near‐term pregnancy. Second, to assess the performance of OA Doppler to rule in and rule out angiogenic factor imbalance.
