Q

Erection of the penis:

A

Arteries bring blood into the penis. This pressure squeezes against the veins, preventing blood from going out again. The penis becomes engorged with blood, causing the erectile tissue of the penis to become firm.

13 times

104
Q

The four phase of the menstrual cycle:

A
  • Menstrual phase
  • Follicular or Proliferative stage
  • Ovulation phase
  • Luteal phase or secretory phase
105
Q

Menstrual Phase

A

The first day of a woman’s period counts as the first day of her menstrual cycle.
Uterus sheds the functional endometrium because there was no fertilized ovum to implant. Normal time range 3-7 days.

106
Q

Follicular or Proliferative stage

A

A Graafian follicle grows an ovum to maturity, and estrogen signals the basal endometrium to start growing a new function endometrium.
The cervix starts to produce less-acidic mucus that will actually assist the sperm in their journey to the fallopian tube. This phase lasts 6-12 days.

107
Q

Ovulation phase

A

Lasts one or two days/ typically occurs midway through the cycle.
When the ovum has nearly matured, the estrogen level is high enough to trigger the pituitary gland to release luteinizing hormone (LH). This causes the ovary to release the ovum. Ovum then enters the fallopian tube and awaits fertilization by the sperm. If fertilized, the ovum will immediately begin to develop, still moving through the fallopian tube. It will take about three days to implant into the endometrium.

108
Q

Luteal phase, or Secretory phase

A

Dominated by the corpus luteum, the “yellow body” created when the ovum left the ovary. The corpus luteum produces hormones to make the endometrium receptive to implantation and early pregnancy.
During this phase, a woman’s body temperature increases. After ovulation, the hormones FSH and LH sustain the corpus luteum. If the egg is fertilized, the resultant embryo will produce the hormone human chorionic gonadotropin (HCG), which can support the corpus luteum instead of LH. If the LH is too low and there’s no embryo to produce HCG, the corpus luteum stops producing hormones to prepare the body for pregnancy. This will be the signal for the endometrium to slough off, starting the cycle all over again. This final phase lasts about two weeks.

109
Q

Zygote

A

Fertilized egg cell

110
Q

Embryo

113
Q

A

114
Q

human chorionic gonadotropin (HCG) is produced by the ….?

A

embryo and sustains the corpus luteum in place of LH.
It’s also the identifying hormone in urine tests for pregnancy.

115
Q

Menopause

A

The cessation of menstruation.
Menopause usually occurs between the ages of 45 to 55, but it can occur earlier or later. Menopause that occurs before age 35 is considered “premature”. If it occurs after age 58, it’s considered “delayed”.

116
Q

Endometriosis

A

A condition where the endometrium (the innermost layer of the uterus) grows out of the uterus. The exact cause of endometriosis is unknown. Some women may have this condition without any symptoms, while others may experience symptoms such as pain during menstruation or during sexual intercourse.
Endometriosis may also interfere with fertility. In younger women who wish to have children, hormone therapy is given as a treatment.
Depending on the severity of the condition, the offending tissues may be removed in surgery and a complete hysterectomy performed to prevent a recurrence.

117
Q

Medications that are also useful to treat endometriosis include:

A

Danazol (Danocrine)
Nafarelin (Synarel)
Lupron Depot

118
Q

Q

Symptoms of genital herpes

A

blisters around the genitals that can break and leave sore ulcers. These ulcers may take two to four weeks to heal at first. The infection can stay in the body indefinitely, but outbreaks tend to become fewer and less severe over the years

132
Q

Medications useful in treating genital herpes include:

A

Acyclovir (Zovirax)
Famciclovir (Famvir)
Valacyclovir (Valtrex)

133
Q

Human papillomavirus (HPV)

A

Very common virus that most people come into contact with at some time during their lives. This virus causes genital warts in both men and women as well as cervical cancer in women. Treatment involves application of acid or liquid nitrogen to destroy the warts.
There are vaccines available to prevent HPV infection in both men and women. The best time to get these vaccines is before becoming sexually active. Vaccines like Gardasil and Cervarix can prevent genital warts and cervical cancer.

134
Q

Gonorrhea

A

Caused by the bacterium Neisseria gonorrhoeae. Men receive more symptoms, such as dysuria (painful urination) and discharge of pus from the penis. Although women may also have dysuria and vaginal discharge, the symptoms are typically milder than those in men. Gonorrhea can cause pelvic inflammatory disease (PID) and infertility in women if left untreated. Gonorrhea can be diagnosed with tests that detect the bacterial genes in urethral or cervical swab samples.
Treatment involves antibiotics

135
Q

Syphilis

A

Infection caused by Treponema pallidum. The initial sign is a genital sore called a chancre. Chronic infection can affect the vertebrae, heart, and central nervous system.
Again, treatment involves antibiotics; refer to the Medications to treat Reproductive System infections list of commonly used antibiotics.

136
Q

Medications to treat Reproductive System infections list of commonly used antibiotics.

A

Acyclovir (Zovirax)
Famciclovir (Famvir)
Valacyclovir (Valtrex)

137
Q

Chlamydia

A

Caused by the bacterium Chlamydia trachomatis. Signs of infection include painful urination and penile or vaginal discharge; symptoms are more prominent in men. Like gonorrhea, this STD can cause PID and infertility in women. Chlamydia can also be diagnosed with new tests that detect the bacterial genes in a urethral or cervical swab sample. Treatment is with antibiotics; refer to the Medications to Treat Reproductive Infections Table for the list of commonly used antibiotics.

138
Q

Trichomoniasis vaginalis
