Difficulty experienced by individual or couple during any stage of normal sexual activity, including physical pleasure, desire, preference, arousal, or orgasm
Sexual desire disorders
Lack or absence, for some period of time, of sexual desire or libido for sexual activity
Sexual arousal disorders
Previously known as frigidity in women and impotence in men, though these have now been replaced with less judgmental terms
Erectile dysfunction (ED)
Sexual dysfunction characterized by the inability to develop or maintain an erection of the penis
The introduction of the first pharmacologically effective remedy for impotence, Sildenafil (Viagra), in the 1990s caused a wave of public attention, propelled in part by the news-worthiness of stories and heavy advertising
Premature ejaculation
Ejaculation occurs before the partner achieves orgasm (<2 minutes from the time of the insertion of the penis), or a mutually satisfactory length of time has passed during intercourse
Orgasm disorders
Persistent delays or absence of orgasm following a normal sexual excitement phase in sexual encounters
Dyspareunia
Painful intercourse, may be caused by insufficient lubrication in women
Vaginismus
Involuntary spasm of the vaginal wall muscles
Vulvodynia or Vulvar Vestibulitis
Burning pain during sexual intercourse related to problems with the skin in the vulvar and vaginal areas
Post-Coital Tristesse (PCT)
Feeling of melancholy and anxiety after sexual intercourse that lasts for up to two hours
Sexual Headaches
Occur in skull & neck during sexual activity, including masturbation, arousal, or orgasm
Post-orgasmic Illness Syndrome (POIS)
In men, it causes severe muscle pain throughout the body and other symptoms immediately following ejaculation
Dhat Syndrome
In men, it causes anxious and dysphoric mood after sex, but is distinct from the low-mood and concentration problems (acute aphasia)
There is no known cure or treatment for Dhat Syndrome
Pelvic floor dysfunction
The underlying cause of sexual dysfunction in both women and men, treatable by physical therapy
Infertility
Inability to conceive & maintain a pregnancy after 12 months (6 months for woman older than 35 years old age) of unprotected sexual intercourse
Primary infertility
Infertility in a couple who have never had a child, the absence of live birth for women who desire a child and have been in a union for at least 12 months, during which they have not used any contraceptives
Secondary infertility
The failure to conceive following a previous pregnancy, the absence of live birth for women who desire a child and have been in a union for at least 12 months since their last live birth, during which they did not use any contraceptives
Infertility may be caused by an infection in the man or woman, but often there is no obvious underlying cause
Couples where infertility lies with the man
In many cultures, the inability to conceive bears a stigma
In closed social groups, a degree of rejection (or a sense of being rejected by the couple) may cause considerable anxiety and disappointment
Causes of infertility
One third - are related to female factors alone
One third - to male factors alone
One third - to a combination of male and female factors
Categories of male causative factors
Endocrine
Spermatogenesis
Sperm antibodies
Sperm transport factor
Disorders of intercourse
Endocrine
Pituitary diseases
Pituitary tumors
Hypothalamic diseases
Low levels of luteinizing hormone (LH)
Low Follicle-Stimulating Hormone (FSH)
Low testosterone can decrease sperm production
Spermatogenesis
The process in which mature functional sperm are formed
Several factors that can affect the development of mature sperm - also referred to as gonadotoxins
Gonadotoxins
Drugs (e.g., chemotherapeutics, calcium channel blockers, heroin, alcohol, and nicotine)
Infections (e.g., prostatitis, sexually transmitted illnesses, and contracting mumps after puberty)
Systemic illness
Heat exposure: Prolonged heat exposure of testicles (e.g., use of hot tubs, wearing tight underwear, frequent bicycle riding)
Pesticides
Radiation to the pelvic region
Sperm antibodies
An immunological reaction against the sperm that causes a decrease in sperm motility (movement of sperm)
Common after vasectomy reversal or testicular trauma
Antisperm Antibody (ASA) has been considered as an infertility cause in around 10–30% of infertile couples
In both men and women, ASA production is directed against surface antigens on sperm, which can interfere with sperm motility and transport through the female reproductive tract, inhibiting capacitation and acrosome reaction, impaired fertilization, influence on the implantation process, and impaired growth and development of the embryo
Spermtransportfactor
Related to anatomy that might be missing or blocked, thus interfering with the transportation of sperm
Causes of sperm transport factor
Vasectomy
Prostatectomy
Inguinal hernia
Congenital absence of the vas deferens
Disorders of intercourse
Erectile dysfunction
Ejaculatory dysfunctions
Anatomical abnormalities
Psychosocial factors
Erectile dysfunction
Inability to achieve and/or maintain an erection
Ejaculatory dysfunctions
Retrograde ejaculation
Psychosocial factors
That can interfere with fertility
Categories of female causative factors
Ovulatory dysfunction
Tubal and pelvic pathology
Cervical mucus factors
Ovulatory dysfunction
Includes an ovulation or inconsistent ovulation
Affect 15%–25% of couples experiencing infertility and have a very high success rate with appropriate treatment
Tubal and pelvic pathology
Damage to the fallopian tubes - related to previous (PID) pelvic inflammatory disease or endometriosis
Uterine fibroids - benign growths of the muscular wall of the uterus, which can cause a narrowing of the uterine cavity & interfere with embryonic & fetal development, causing a spontaneous abortion
Cervical mucus factors
Cervical surgeries such as cryotherapy a medical intervention used to treat cervical dysplasia
