Explore human sexuality and reproduction, from mammal pregnancy and breastfeeding to comprehensive sex education, covering anatomy, contraception, consent, pregnancy duration of 38 to 40 weeks, relationships, and safe practices.
Testosterone, the male hormone, is produced by the leading cells and drives sexual development, including testicular descent, spermatogenesis, libido, voice deepening, puberty, and increased muscle mass via protein synthesis.
Explore penis anatomy, including skin, subcutaneous fat, dorsal vessels and nerves, two corpora cavernosa, the corpus spongiosum with the urethra, the shaft and glans, and the foreskin.
Discover the anatomy of female external genitalia, including mons pubis with pubic hair, labia majora and labia minora, the clitoral hood and body, vestibule, urethral and vaginal openings, and hymen.
Explore clitoral anatomy, including the glands and shaft, their erectile tissue, and the role of clitoral stimulation in sexual arousal and female pleasure.
Explain sperm and semen, noting the haploid 23 chromosomes in sperm versus 46 in body cells. Cite semen’s composition from seminal vesicles, prostate, and testes.
Learn semen composition from prostate and seminal vesicle contributions, with zinc, citric acid, acid phosphatase and immunological material that protect sperm, while alkaline semen neutralizes vaginal acidity to enable fertilization.
Fertilization can be defined as the union of two haploid gametes, the spermatozoa and the oocyte, hereto referred to as egg, to restore the diploid state, form a zygote through the process of egg activation, and commence a series of mitotic divisions that results in cell differentiation and embryo development. - sciencedirect.com
Explore syphilis, caused by Treponema pallidum, from the primary painless lesion shenker to secondary rashes on the palms and feet. Learn about latent and tertiary phases with neuro syphilis.
Gonorrhea is a curable sexually transmitted infection caused by Neisseria gonorrhoeae, presenting with genital discharge and burning urination, inflaming the vaginal tract or urethra, treated with antibiotics.
Identify Chlamydia trachomatis as the world's most common sexually transmitted bacterial infection. It affects the genital tract and eyes (trachoma), with risks of infertility and blindness.
Human beings are sexual beings. We are mammals. We reproduce through sexual intercourse and the female produces breast milk to nourish the newborn. This is unlike reptiles and birds who have sexual intercourse and lay eggs outside. We as mammals develop the child for 38 to 40 weeks in the uterus of our female.
Reproductive biology includes both sexual and asexual reproduction. Reproductive biology includes a wide number of fields: Reproductive systems Endocrinology Sexual development Sexual maturity Reproduction Fertility
Reproductive biology involves the scientific study of the reproductive system. Improved understanding of reproductive biology can lead to new treatments for reproductive disorders, such as infertility.
In this course, you will learn about the reproductive system including both anatomy and physiology, fertility, in-vitro fertilization, sperm, semen, menstrual cycle and disorders associated with it.
The division focuses on reproductive biology includes the study of biochemistry, physiology, endocrinology, cell biology, genetics, and molecular biology of a wide range of biological processes involved in reproduction. This research has broad applications in public health, medicine, and agriculture, including contraception, infertility, reproductive toxicology, animal science, and oncology.
Fertility is the quality of being able to produce offspring through reproduction following the onset of sexual maturity. As a measure, the fertility rate is the average number of children that a female has in her lifetime and is quantified demographically. Fertility is most commonly considered when there is a difficulty or an inability to reproduce naturally, and this is also referred to as infertility.
