Association between Hidradenitis Suppurativa and Abnormalities in Semen Parameters and Sexual Function: A Pilot Study.

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease affecting patients of reproductive age. Although HS shares risk factors with male infertility, only 1 epidemiological study has evaluated this association. To further evaluate this potential association, findings on semen and hormonal analysis, testicular ultrasound, and the International Index of Erectile Function (IIEF-15) were compared between 28 men attending a tertiary HS clinic during the period April 2019 to April 2021, and 44 healthy controls, spouses of infertile women undergoing semen evaluation before in vitro fertilization.

Single men's attitudes towards posthumous use of their sperm cryopreserved due to illness in Israel.

Background: Banking of frozen spermatozoa by single men opens the possibility of procreation long after their death. Requests for posthumous reproduction by the families of the deceased are growing, raising an ethical debate, especially when written instructions were not left by the patients and in cases of unplanned perimortem collection. The issue of the progenitors' intention to procreate after death is the key to ethically based decision-making in these cases.

Sugar Consumption Is Negatively Associated with Semen Quality.

Recently, in parallel to decrease in semen quality, the consumption of sugar has risen sharply. This provided the rationale to study the association between whole dietary sugar consumption and semen quality. Our aim was to investigate the association between sugar consumption and semen quality.

The absence of spermatogenesis in radical orchiectomy specimen is associated with advanced-stage nonseminomatous testicular cancer.

Background: To assess if clinical, pathological, and spermatogenesis factors are associated with clinical staging in patients with testicular germ cell tumors.

Patients And Methods: We retrospectively reviewed the pathology reports and slides from 267 men who underwent radical orchiectomy for testicular cancer at our institution during 1998-2019. Histologic slides were reviewed and the presence of mature spermatozoa was documented.

Does the time interval from the end of sperm processing to intrauterine insemination (lab-to-uterus time) affect treatment outcome?

Background: Intra-uterine insemination is an essential component in the treatment of infertility. Success rates are dependent on clinical factors of the female partner, sperm quality, and preparation technique. The effect of the time interval between the end of sperm preparation in the lab, and its injection into the uterine cavity (lab-to-uterus time) is yet to be determined.

Dietary patterns are positively associated with semen quality.

Objective: To study association of semen quality with a priori whole dietary pattern indexes, which reflect real-world dietary practices and the numerous combinations by which foods are consumed: Healthy Eating Index (HEI), Dietary Approaches to Stop Hypertension (DASH), alternate Mediterranean Diet score (aMED), and Alternative Healthy Eating Index (AHEI).

Design: A cross-sectional single-center study.

Setting: Hospital fertility center and university.

Attempts to improve human ovarian transplantation outcomes of needle-immersed vitrification and slow-freezing by host and graft treatments.

Purpose: To investigate if needle-immersed vitrification or slow-freezing yields better implantation results for human ovarian tissue and which method benefits more when combined with the "improvement protocol" of host melatonin treatment and graft incubation with biological glue + vitamin E + vascular endothelial growth factor-A.

Methods: Human ovarian tissue was preserved by needle-immersed vitrification or slow-freezing and transplanted into immunodeficient mice, either untreated (groups A and C, respectively) or treated with the improvement protocol (groups B and D, respectively). Grafted and ungrafted slices were evaluated by follicle counts, apoptosis assay and immunohistochemistry for Ki67 and platelet endothelial cell adhesion molecule (PECAM).

Predictors of spermatogenesis in radical orchiectomy specimen and potential implications for patients with testicular cancer.

Objective: To assess the ability of semen analysis and other patients' characteristics to predict the presence of spermatozoa in radical orchiectomy pathological specimen, and describe potential implications for patients with azoospermia and testis cancer.

Design: Retrospective cohort study.

Setting: Tertiary hospital.

Severe combined immunodeficiency (SCID): from the detection of a new mutation to preimplantation genetic diagnosis.

Purpose: To describe the identification of a new mutation responsible for causing human severe combined immunodeficiency syndrome (SCID). In a large consanguineous Israeli Arab family, this served as a diagnostic tool and enabled us to carry out preimplantation genetic diagnosis (PGD). We also demonstrated that PGD for homozygosity alleles is feasible.

Enhancement of bony in-growth to metal implants by combining controlled hydroxyapatite coating and heat treatment.

The rate of bony in-growth to heat-treated and controlled hydroxyapatite metal implants made of either titanium alloy (Ti-6Al-4V) or stainless steel (SS) 316L inserted to the medullar canal of the femur in rats was investigated. It was found that while partial coverage of hydroxyapatite (HA) did not cause a significant elevation of their bonding strength when compared with nonheated implants, HA, and heat treatment caused a significant (p < 0.01) elevation of 3.
