Background Assisted conception (AC) methods, including in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI), have transformed reproductive medicine by offering solutions to infertility. However, their long-term health implications, particularly on neurological outcomes in children, require further investigations, especially in the Middle East. Objective This study aimed to evaluate the neurological complications among children conceived through assisted reproductive techniques at King Khalid University Hospital, a tertiary hospital in Riyadh, Saudi Arabia. Methods A descriptive retrospective review was conducted on the records of pediatric patients born via assisted conception between January 2017 and December 2022. Eligible children aged 18 months and older were included. Data on demographic characteristics, antenatal and postnatal complications, and neurological assessments were collected and analyzed using the Statistical Package for Social Sciences (SPSS) version 21 (IBM Corp., Armonk, NY). Results Out of 303 patients, 283 children met the inclusion criteria, with a mean age of 4.1 ± 1.7 years. Most deliveries were via cesarean section (CS) (194, 68.6%). Premature births accounted for 129 (45.6%), with antenatal complications reported in 58 (45.0%). The primary neurological sequela identified was speech disorder, affecting 18 children (6.4%), with a smaller proportion experiencing behavioral issues (eight, 2.8%) and motor delays (five, 1.8%). Significant associations were found between neurological complications and factors such as very preterm status, low birth weight (LBW), neonatal intensive care unit (NICU) admission, and associated complications during NICU stays. Conclusion Although the majority of children conceived through assisted reproductive techniques exhibit no significant complications, those born prematurely appear to have a higher risk of neurological issues. These findings underscore the importance of ongoing monitoring for children born through assisted conception, particularly those with identified risk factors. Future prospective studies are necessary to further elucidate these associations and improve clinical outcomes for this population.

Study Question: Do the main psychoactive phytocannabinoid delta-9-tetrahydrocannabinol (THC) and its non-psychoactive analog cannabidiol (CBD) affect human sperm function?
Summary Answer: THC and CBD affect the sperm-specific Ca2+ channel CatSper, suppress activation of the channel by progesterone (P4) and prostaglandin E1 (PGE1), and THC also alters human sperm function in vitro.
What Is Known Already: Marijuana (Cannabis sativa) is one of the most commonly used recreational drugs worldwide. Although the effects of phytocannabinoids on semen parameters have been studied, there is no evidence of a direct impact of THC and CBD on human sperm.

: Male infertility is a complex, multifactorial condition influenced by infectious, inflammatory, and autoimmune components. Immunological factors, though implicated in reproduction, remain poorly understood. This study aims to deepen the understanding of infections, inflammation, and autoimmune factors in male infertility, with a focus on immune-related disorders affecting the testes and epididymis-immunologically privileged but vulnerable sites.

Background: Global fertility decline has led to increased use of assisted reproductive technology (ART), raising concerns about genetic risks to offspring. This study aimed to investigate cystic fibrosis transmembrane conductance regulator (CFTR) variants in Chinese families and assess their association with pregnancy complications and neonatal outcomes.
Methods: This prospective cohort study included 446 Chinese families (148 natural conceptions, 298 ART conceptions) who underwent whole genome sequencing.

With the development of modern society and prolonged education, more women choose to delay their childbearing age, which greatly increases the number of women aged older than 35 years with childbearing needs. However, with increasing age, the quantity and quality of oocytes continue to fall, especially with increasing aneuploidy, which leads to a low in vitro fertilization (IVF) success rate, high abortion rate and high teratogenesis rate in assisted reproduction in women with advanced maternal age. In addition to genetics and epigenetics, follicular metabolism homeostasis is closely related to ovarian aging and oocyte aneuploidy.

In vitro fertilization, cryopreservation and pre-implantation genetic testing are transformative reproductive technologies offering hope for individuals facing fertility challenges. Scientifically, understanding the science of developmental biology is essential for comprehending the mechanisms and implications of these technologies. In embryological sciences, biological perspectives identify life as a series of developmental stages ranging from conception to viability, each potentially representing a different 'beginning' of life.
