- Infertility is defined as the inability of a sexually active couple to conceive after 1 year of regular intercourse without contraception, affects approximately 15% of couples...
A correlation between obesity and male fertility has been observed in a few clinical studies. Normal weight men appear to have higher sperm concentrations and sperm motility when compared ...
Men are recruited to collect seminal plasma samples and serum samples from men with azoospermia, men receiving medical treatment of infertility and men attending semen analysis. MicroRNA (...
This study is being conducted at the University Hospital of Lund University in Malmo, Sweden, in collaboration with the U.S. National Institute of Child Health and Human Development. The ...
The investigators are conducting a placebo-controlled, randomized control trial with duloxetine in healthy, fertile men not previously on any antidepressants. Participants will be randomiz...
The association of varicoceles with infertility is well established, but the exact effect of varicoceles on semen quality among patients with infertility is still poorly known. The study aimed to exam...
A thiol group plays an essential role in sperm metabolism and the antioxidative defense state. Zinc is the second most abundant element in the human body, following iron. The present study was conduct...
Teratozoospermia is a disorder associated with high abnormal sperm morphology which affects fertility in males. In recent years, it has been described that biomarker-based sperm quality evaluation can...
A recent study found that three recurrent deletions of X chromosome linked copy number variations (CNVs), CNV64, CNV67 and CNV69 were associated with idiopathic male infertility in Spanish and Italian...
Non-protein coding RNA, miRNAs (microRNAs), are a class of promising molecular biomarkers for forensic body fluid identification (BFI) as their small size and tissue-specific expression manners. A num...
A scientific or medical discipline concerning the study of male reproductive biology, diseases of the male genital organs, and male infertility. Major areas of interest include ENDOCRINOLOGY; SPERMATOGENESIS; semen analysis; FERTILIZATION; CONTRACEPTION; and CRYOPRESERVATION.
A form of male HYPOGONADISM, characterized by the presence of an extra X CHROMOSOME, small TESTES, seminiferous tubule dysgenesis, elevated levels of GONADOTROPINS, low serum TESTOSTERONE, underdeveloped secondary sex characteristics, and male infertility (INFERTILITY, MALE). Patients tend to have long legs and a slim, tall stature. GYNECOMASTIA is present in many of the patients. The classic form has the karyotype 47,XXY. Several karyotype variants include 48,XXYY; 48,XXXY; 49,XXXXY, and mosaic patterns ( 46,XY/47,XXY; 47,XXY/48,XXXY, etc.).
The inability of the male to effect FERTILIZATION of an OVUM after a specified period of unprotected intercourse. Male sterility is permanent infertility.
An assisted fertilization technique consisting of the microinjection of a single viable sperm into an extracted ovum. It is used principally to overcome low sperm count, low sperm motility, inability of sperm to penetrate the egg, or other conditions related to male infertility (INFERTILITY, MALE).
The period in the MENSTRUAL CYCLE that is optimal for FERTILIZATION of the OVUM and yielding PREGNANCY. The duration of fertile period depends on the life span of male GAMETES within the female reproductive tract and the time of OVULATION. It usually begins a few days before ovulation and ends on the day of ovulation.
