Assisted Reproductive Technologies and Offspring's School Grades by Maternal Education

Paediatric and Perinatal Epidemiology, EarlyView.
ABSTRACT Background Children conceived through assisted reproductive technologies (ART) often achieve higher school grades than spontaneously conceived peers in unadjusted analyses, a pattern largely attributed to the socio‐economic advantage of parents who use ART.

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 ...

Thyroid antibody positivity in pregnancy is associated with altered reproductive hormone concentrations and placental growth in Lewis rats

The Journal of Physiology, EarlyView.
Abstract figure legend Thyroid antibody positivity (TAb+) in pregnancy is associated with adverse pregnancy outcomes, but the mechanisms are unclear. This study developed a rodent model of TAb+ in pregnancy, induced prior to mating so that TAb+ exposure occurred throughout the pregnancy. TAb+ did not alter thyroid hormone concentrations and had minimal

Can Hormonal Therapy Improve the Outcomes of mTESE in Patients With Non‐Obstructive Azoospermia?

Andrology, Volume 14, Issue 6, Page 1859-1872, September 2026.
ABSTRACT Background Non‐obstructive azoospermia (NOA) represents the most severe form of male infertility. Hypogonadism is common in NOA patients, and normal testosterone (T) levels are considered essential for spermatogenesis. Fertility‐preserving hormonal therapy (FpHT) has been proposed to optimize hormonal milieu and improve sperm retrieval rates ...

Complications and adverse outcomes in pregnancy and childbirth among women who conceived by assisted reproductive technologies: a nationwide birth cohort study of Japan environment and children’s study

BMC Pregnancy and Childbirth, 2019
Background Although pregnancies conceived by assisted reproductive technology (ART) have a higher risk of maternal/perinatal complications, the overall risk of adverse outcomes necessitating advanced obstetric care has not been closely examined.

Fish Sperm Subpopulations Detection, Separation, and Application: Current State and Trends

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
Modern advances in sperm biology highlight the necessity of recognising intra‐ejaculate heterogeneity as a central concept for advancing both the fundamental understanding of fertilisation processes and the development of artificial reproduction techniques in fishes. ABSTRACT Sperm subpopulations represent a fundamental manifestation of intra‐ejaculate

[Intracytoplasmic sperm injection].

Tidsskrift for den Norske laegeforening : tidsskrift for praktisk medicin, ny raekke, 1998
The first results of intracytoplasmic sperm injection (ICSI) in Norway are presented. Acceptable fertilization rates were obtained for all indications; severe male infertility, as well as moderately reduced sperm quality where in vitro fertilization (IVF) and embryo transfer had previously failed.

Optimizing outcomes in intrauterine insemination: A narrative synthesis of two decades of clinical research (2000–2024)

International Journal of Gynecology &Obstetrics, Volume 174, Issue 2, Page 718-729, August 2026.
Abstract Intrauterine insemination (IUI) is a widely used first‐line fertility treatment, yet its success rates vary considerably. This review synthesizes evidence from peer‐reviewed studies published between 2000 and 2024, including randomized controlled trials, cohort and case–control studies, as well as systematic and narrative reviews identified ...
